UNITED STATES PHOSPHORUS LOADS
TO LAKES ERIE AND ONTARIO
AND SAGINAW BAY FOR 1982
Prepared by: Paul J. Horvatin

Introduction
Annex 3 of the 1978 Great Lakes Water Quality Agreement and its Supplement
requires that both the United States and Canada confirm future phosphorus
loads and establish load allocations and compliance schedules for meeting
those loads. The Annex 3 Supplement establishes phosphorus target loads and
load reductions for the Lower Lakes, Lakes Erie and Ontario, and Saginaw Bay.
In order to provide the Great Lakes States with a basis for state and
river basin load planning, it is necessary to have an estimate of the loading
from each tributary and the amount of potential load reduction. For this
report it was agreed that the 1982 water year would be used as a base year
for Lakes Erie and Ontario and the 1980 water year for Saginaw Bay.
This report summarizes total phosphorus loads for water year 1982 by major
river basins and includes municipal and industrial point sources as well as
nonpoint sources. The intent of this report is to partition the known phosphorus
load to the Lower Lakes into its tributary origins and point/nonpoint compon-
ents. The report and any conclusions derived from it are totally dependent
on the reliability and accuracy of the phosphorus load data bases. Some of
the tributary load values are estimated since neither flow nor concentration
data is routinely collected on a regular basis. Unmonitored tributaries are
listed for Lakes Erie and Ontario. Point source data is reported by each
discharger as required by the NPDES permit system for both monitored and
unrnonitored tributaries. Overall there does appear to be satisfactory corre-
lations between lake phosphorus concentrations and reported loadings.
Figures 1, 2, and 3 summarize phosphorus loads for Lake Erie, Lake Ontario and
Saginaw Bay, respectively. Total hydrologic drainage area loads and basin
loads including all components are provided. Excess municipal loads, which are
those loads above or below a 1.0 mg/1 effluent phosphorus concentration, are
given. A negative excess load means that a single or group of municipal
facilities are collectively discharging effluent with a phosphorus concentration
below 1.0 mg/1. A positive excess load means that the facilities are
discharging an effluent with a phosphorus concentration above 1.0 mg/1. This
positive excess load is that amount of phosphorus which is expected to be
reduced when the facilities comes into compliance with the 1.0 mg/1 effluent
phosphorus requirement.
Methodology
The study period for this report is water year 1982 (October 1981 - September
1982). This year was chosen because it is the most recent year for which
complete and accurate tributary phosphorus data and point source data is
available. Based on U.S. Geological Survey (USGS) Great Lakes tributary flow
data, (water resources data-Michigan, Ohio, Indiana, New York, Pennsylvania,
1982) water year 1982 in general appears to be representative of average or
near normal stream flow conditions in the lower lakes Basin. Exceptional
rainfall events in any specific tributary may have occurred during the water
year. Reported phosphorus loads from tributaries with exceptionally high or
low flow events should be carefully evaluated by the reviewer.
Lakes Erie and Ontario and Saginaw Bay drainage basins were subdivided into
hydrologic areas (complexes and river basins) following the procedures used in
the U.S. Task D reports on Great Lakes Pollution From Land Use Activities by
the international Joint Commission. River Basin group maps and a brief
narrative description of each hydrologic area is included as Appendix 1
-------
-2-
Municipal and industrial point sources were divided into direct and indirect
discharges for each major drainage basin to avoid double counting of phosphorus
loads. Direct discharges are defined as a point source of phosphorus below
the tributary monitoring station or having an outfall discharging into the
lake proper. Indirect discharges are defined as a point source above the
tributary monitoring station so that the tributary load calculated at the
monitoring station includes those point sources. All known point sources of
phosphorus for each drainage basin are listed in Appendix 2.
The 1982 phosphorus load for each hydrologic area was calculated by adding
the tributary component and direct municipal and industrial point sources.
The nonpoint component of each hydrologic area phosphorus load was calculated
by subtracting the indirect municipal and industrial point source loads from
the tributary load. (See figures 1, 2 and 3 for examples) The assumption for
these calculations is that the tributary load accounts for all sources of
phosphorus within the drainage basin including indirect point sources, non
point, and natural background.
Sources of Data
Tributary phosphorus load data was obtained from Dr. John Clark, International
Joint Commission (IJC) Windsor, Ontario Regional Office. Dr. Clark prepares
annual phosphorus tributary loading summaries for each of the Great Lakes as
secretariat to the IJC Water Quality Board's Surveillance Workgroup.
Tributary flow data from USGS gaged streams and phosphorus concentration
data from USGS, USEPA and State monitoring stations is used to calculate
tributary loads. When tributary sampling is conducted on varying frequencies
(i.e. monthly grab, 24 composite etc.) during the water year, a stratum or
grouping of data is established for each distinctive sampling frequency. Daily
grab samples for example are not averaged with 24 hour flow weighted samples.
Each sample frequency is treated as a distinct data set. The reference for
the methodology used is discussed in Sampling Techniques by William Cochran,
3rd Edition John Wiley & Son.
Phosphorus loads are estimated for unmonitored tributaries by using a unit
area ratio of an adjoining monitored tributary less its point sources.
Appendix 3 lists for Lakes Erie and Ontario those tributaries which are
monitored and unmonitored in addition to phosphorus loads in metric tons/year.
1980 tributary load data was used for Saginaw Bay since it was the only year
for which complete monitoring data is available for all rivers in the basin.
Point source load data for phosphorus is reported by each of the Great Lakes
States for all major and significant municipal and industrial dischargers.
The State Pollution Control Agencies receive their data from each of the
NPDES permitted dischargers on a monthly basis. The data is then collected and
summarized by USEPA annually for transmittal to the International Joint Commission,

Summary
Figure 4 summarizes the total phosphorus load to Lake Erie, Lake Ontario and
Saginaw Bay. Each of the components of the total load, tributary, point and
non-point, are quantified. Based on the assumption that water year 1982 was
generally representative of stream flow conditions in the Lower Lakes and
Saginaw Bay, these loads should provide a perspective of the tributary origins
and source magnitude of phosphorus. The total load and its components are
quantities of total phosphorus actually delivered to the Lakes in 1982. The
delivered load has not been adjusted nor corrected to reflect long term
conditions or averages.

Black Creek (St. Clair)'
The Black River encompasses an area of 180,000 hectares (446,000 acres). In the
central portion of Michigan's Lower Peninsula the Black River has a mean annual
Hlrharee of 7.8 m3's (275 cfs). An important tributary to the Black River is
Mill Creek The area is generally flat and has a significant amount of wetlands.
.Approximately 20 percent of area exists as scattered forested areas about 60
percent is (utilized in agriculture, and 10 percent is urbanized. The bedrock
consists primarily of sandstone. The material covering the bedrock is composed
of silt and clay near the shore and glacial till throughout the rest of the b.asin.
Important gas fields and salt formations exist in the area Approximately three
najor municipalities and four major industries use the surface waters of this area
Tor waste assimilation. The cities of Port Huron (pop.: 35,794), and Marysville
(pop.: 5,610) are the major population centers in the area.

Clinton River
The Clinton River drains an area of 155,000 hectares (383,000 acres). The
area is located in the southeast portion of Lake Michigan's Lower Peninsula. The
Clinton River has a mean annual discharge of 14.3 m^'s (505 cfs) and drains
*into Lake S^. Clair. Major tributaries to the Clinton River are the North
Branch, Paint Creek, and Red Run. There are several additional small streams that
also provide drainage for the area. The topography varies from flat to rolling
with few wetlands. About 15 percent of the area is forested, 50 percent
agriculturalized, and 20 percent found in highly developed metropolitan areas.
The bedrock is composed primarily of sandstone. The surface material consists
of silt, clay and glacial till. Heavy industrial development, to a large extent
associated with the automotive industry, is a major influence on the water
quality of this area. A considerable amount of the area's municiple waste
is treated by Detroit Water Services and discharged to the Rouge River in
Hydrologic Area 4.1.4. However, there still is significant municiple and
industrial discharge into the surface waters. The Clinton River is characteris-
tically sluggish (as many of the streams draining into the western portion of
Lake Erie) and carries a high silt load. Cities of Pontiac (pop.: 85,279),
Mt. Clements (pop.: 20,476), and Rochester (pop.: 7,054) are the major
concentrated population centers in the area.

Rouge Complex
The Rouge Complex encompasses an area of 189,000 hectares (468,00 acres).
The Complex is located in the southeast portion of Michigan's Lower Peninsula.
The major tributary in the area is the Rouge River, which has a mean annual
discharge of approximately 6.4 m s (226 cfs). Major tributaries to the Rouge
^ River are the Upper, Middle, and Lower Rouge Rivers. The area is generally
flat with few wetlands. Approximately 15 percent of the area is forested,
another 20 percent devoted to agriculture, and over 50 percent consists of the
highly developed Detroit Metropolitan Area. Bedrock is composed of sandstone
and shale. The overlying material consists of silt and clay with some
glacial till. Heavy industry, to a large extent associated with the automobile
industry, effects the water quality of this Complex. There is some peat,
clay, salt, and sand and gravel extracted from the area. A large number of
major industries and numerous combined sewer overflows discharge wastewater
into the surface waters of this Complex. The Rouge River drains much of metro-
poliaton Detroit (approximate population 3,000,000), subjecting the river
to severe human pressure.

Maumee River
The Maumee River, the largest tributary to the Great Lakes, drains an area
of approximately 1,711,000 hectares (A, 229,000 acres). Seventy-three and six
tenths percent of the area is located in northwest Ohio, with 19.4 percent in adjoining
Indiana and the remaining 7 percent in Michigan. The Maumee River has a mean annual
discharge of 134.7 m s (4,756 cfs). The lower reaches of the Maumee are subject
to esturine effects. The major tributaries to the Maumee are the St. Joseph River,
the Auglaize River, the St. Mary's River, and the Tiffin River. Much of the land is
nearly level or gently sloping. The fine textured glacial tills and lakelaid
clays have poor natural drainage. The soils have slow permeability, and are
subject to intensive row cropping. A glacial depression, formerly known as the
Great Black Swamp, covers a large portion of the basin. Because the region is
poorly drained, drainage ditches and subsurface tile drains have been constructed
to remove water from much of the agricultural land. Approximately 85 percent
of the area within the hydrologic boundaries is used for agricultural purposes.
Eleven percent of the area is found in urbanized areas with nearly 70 percent of the
population located in the three major areas of Fort Wayne, Indiana, Lima, Ohio,
and Toledo, Ohio. Another 8 percent of the area can be classified as forest and
woodland. The bedrock consists mostly of sandstone in the northwest section of the
area and dolomite in the southeast. Bands of shale are interspersed throughout the
area. The economy is based on manufacturing and agriculture with some extraction
of natural resources such as sand, gravel, limestone, dolomite and clay.
The heavy sediment load and its associated contaminants of the Maumee River is
a major source of pollution to Maumee Bay and Lake Erie in general. The surface
waters of the area receive a heavy point source load of wastewater. More than
150 municipalities, industries, and private wastewater sources use these surface
waters for waste assimiliation. Important municipal and industrial centers in the
area are the cities of Fort Wayne, Indiana (pop.: 177,671), Toledo, Ohio (pop.:
383,818), Lima, Ohio (pop.: 53,734), Findlay, Ohio (pop.: 35,800), Van Wert,
Ohio (pop.: 29,194), Defiance, Ohio (pop.: 16,281), and Maumee, Ohio (pop.: 15,937).

A number of other small streams drain the remaining area. The Complex is flat with fe
wetlands although the area is highly underdrained and ditched. Less than 10
percent of the area is forested, approximately 80 percent is devoted to agriculture,
and about 10 percent is urbanized. The bedrock is composed primarily of dolomite.
The overlying material is predominantly a mixture of silt and clay near the shore and
glacial till throughout the remainder of the complex. Streams in this area are
usually high in dissolved solids. The cities of Bowling Green (pop.: 21,760),
Fostoria (pop.: 16,037), and Port Clinton (pop.: 7,202) are the largest population

Cuyahoga River
The Cuyahoga River drains an area of 234,000 hectares (578,000 acres) in
northeastern Ohio. The Cuyahoga River has a mean annual discharge of 21.6 m^/s
(763 cfs). The topography varies from rolling to steep hills with relatively few
wetlands. Approximately 40 percent of the area is devoted to agriculture, 20
percent forested, and 20 percent urbanized. The bedrock is composed predominantly
of shale near the shoreline and sandstone throughout the rest of the area. The
overlying material is composed of silt and clay near the shore with an area of sand and
gravel in the southern portion, and glacial till throughout the remaining regions
The economy is based mainly on manufacturing. Large amounts of municipal and
industrial wastewater enter the surface waters from metropolitan Cleveland (pop.:
750,903) and Akron (pop.: 275,425), as well as the cities of Cuyahoga Falls
(pop.: 49,678), and Kent (pop.: 28,103). Steel and chemical industries are
prevelent along the Cuyahoga River.

Chagrin Complex
The Chagrin Complex covers 77,000 hectares (189,000 acres) in northwestern
Ohio. The major tributary draining the area is the Chagrin River, which has a mean
annual discharge of 9.0 nr's (318 cfs). Approximately 5 other small streams drain
the remaining areas of this complex. The area has a steep rolling topography
with relatively few wetlands. Approximately 40 percent of the area is agriculturalized,
about 25 percent forested, and about 20 percent urbanized. The bedrock in the northern
portion of the area is predominantly composed of shale and to a lesser extent, sand-
stone. The overlying material consists of mostly silt and clay near the shore .with
glacial till throughout the rest of the region. The economy is based upon manufacturing
with some agriculture and mineral extraction. The area is subject to heavy human
pressure from the cities of East Cleveland (pop.: 39,600), Willoughby (pop.: 18,634),
Chagrin Falls (pop.: 4,848) and portions of Cleveland (pop.: 750,903). Sheet
erosion also causes a serious water quality problem.

Ashtabula-Conneaut Complex
The Ashtabula-Conneaut Complex encompasses an area of 90,000 hectares (220,000
acres). Fifty-four percent of the area is located in northeastern Ohio with the
remaining A6 percent in bordering Pennsylvania. The major tributaries in the area
and their mean annual discharges are the Ashtabula River A.I m^'s (1A5 cfs) and
the Conneaut Creek 7.2 m^/s (25A cfs). The topography varies from flat to rolling
vith few wetlands. The Ashtabula basin is characterized by high runoff.
Approximately 30 percent of the area is forested, about AO percent is devoted to
agriculture, and about 15 percent urbanized. The bedrock is composed mostly of dolomite.
The bedrock is covered by a combination of silt and clay near the shore areas, and glacial
till throughout the remaining area. The economy is based heavily upon manufacturing.
The lower reaches of the Ashtabula River are affected by municipal and industrial
wastewater discharges from the city of Ashtabula (pop.: 2A.313). The Ashtabula
has a relatively small drainage basin and a relatively low flow, resulting in a low
dillution potential. During periods of low natural flow, efflent from the
Ashtabula industrial complex dominates the rivers discharge.

Hydrologlc Area 5.1.2
Genesee River Complex
The Genesee River drains an area of 642,000 hectares (1,586,000 acres).
Ninety-six percent of the area is located in western New York with the remaining
four percent in Pennsylvania. The Genesee River has a mean annual discharge
of 76.8 m3/s (2,712 cfs). Major tributaries to the Genesee River are the
Canaseraga Creek, the Otatka Creek, the Black Creek, and the Honeoye Creek.
A barge canal crosses the Genesee River south of Rochester. Guard Locks, located
on either side of the river crossing, permit regulation of canal water diverted
from Lake Erie. The River has a low slope and many meanders in the lower reaches
which results in generally sluggish flow and estuarine effects during low
flow conditions. The southern region is characterized by steep rugged terrain,
changing to a gently rolling look in the north. There are few wetlands.
Approximately 30 to 40 percent of the area is forested, roughly 50 percent is
devoted to agriculture, and about 10 percent is urbanized. Bedrock is composed
mostly of dolomite and shale. The overlying material is mostly glacial till
with some silt and clay. Severe soil erosion occurs in the upper reaches of
the watershed. The economy is based upon manufacturing and agriculture in the
northern areas with agriculture and forestry being the dominate influence in
the south. Approximately four municipalities and three industries induce the
greatest pressure upon the river. Discharge from the barge canal also seriously
degrades water quality in the river. The city of Rochester (pop.: 296,233) at
the mouth of the Genesee River is the most highly industrialized region within
this hydrologic area.

Oswego River
The Oswego River drains an area of 1,316,000 hectares (3,252,000 acres) in
north ,central New York. The Oswego River has a mean annual discharge of
183 m /s (6,462 cfs). This area drains the bulk of New York's Finger Lakes
Region. A significant feature of this complex is the New York State Barge
Canal which completely transects this complex in an east-west direction. The
topography varies from rolling in the northern portions to mountainous in the
south. There are some wetlands in the eastern region of this area.
Approximately 30 percent of the area is forested, about 40 percent is
agriculturized, about 5 percent is urbanized, and nearly 5 percent of the complex's
area is covered by lakes. The large number of lakes has a modifying effect on
runoff. The bedrock is composed largely of dolomite in the northern sections and
sahle in the south. The cover material is composed mostly of glacial till with
some areas of sand and gravel. The economy is based heavily upon manufacturing
with some agriculture and mineral extraction (limestone and dolomite, salt,
clay, and sahle). The Oswego River receives heavy organic loadings from three
municipalities and six major industries scattered throughout the area. Additional
treated wastewater loads are introduced by the New York State Barge Canal, and
over 60 industries scattered throughout the metropolitan Syracuse area. The
cities of Syracuse (pop.: 197,208), Oswego (pop.: 23,844), Auburn (pop.: 34,599),
Ithaca (pop.: 26,226), and Fulton (pop.: 23,844)., are the most populated and
industrilized centers in this area.

Salmon Complex
The Salmon Complex encompasses an area of 273,000 hectares (674,000 acres) in
north central New York on the eastern shore of Lake Onatrio. The major.,tributaries
in the area are Sandy Creek, which has a mean annual discharge of 6.9m /s (244
cfs), the Salmon River (ungaged), and the Little Salmon River (ungaged). Many
additional small streams drain portions of this area. The topography varies from
rolling to flat. Wetlands are significant. Approximately 50 percent of the
area is forested, about 40 percent is agriculturized, and roughly 5 percent is
urbanized. Bedrock is composed mostly of shale. The overlying material consists
of silt and clay near the lake shore and glacial till throughout the remaining
area. The major population center in the area is the city of Pulaski
(pop.: 2,480). There are no important wastewater discharges in the area.

Hydrologic Area 5.3.1
Black River
The Black River drains an area of 521,000 hectares (1,289,000 acres) in
northcentral New York. The Black River has a mean annual discharge of 110.0 m /s
(3,884 cfs). Major tributaries to the Black River are the Moose River, the Beaver
River, and the Deer River. The Black River and its tributaries have many natural
falls, which are used extensively for power generation. The topography varies
from rolling near the lake shore to mountainous in the eastern states. Annual
runoff in the Basin is high. Some of the 30 hydroelectric developments in the
Basin cause alteration in the flow of the river system. Approximately 60 to 70
percent of the area is forested, 20 to 30 percent is agriculturized, and about
5 percent is urbanized. The bedrock consists predominately of igneous and meta-
morphic rock, although significant shale is found in the western portions. The
overlying material predominantly consists of a silt and clay mixture near the lake
shore areas and glacial till throughout the remainder of the region. Numerous
paper and pulp mills use the Black River for waste assimilation. The cities of
Watertown (pop.: 30,787), and Carthage (pop.: 3,889) are the most populated and
industrialized centers within the area.

Perch Complex
The Perch Complex covers 126,000 hectares (311,000 acres) in north-central
New York. The major tributaries draining this area are the Perch River, Chaumout
River, and Chippawa Creek, all of which are ungauged. The area is generally flat
with few wetlands. Approximately 60% of the land is forested, 40% is devoted to
agriculture, with only a small fraction of the area urbanized. The sandstone and
carbonate bedrock is overlain with silts and clays of a former lake bed. The local
economy is based largely on agriculture, forestry, and food-processing activities.
Wastewater is discharged by several dairy plants, paper mills and small munici-
palities. The largest population centers in this sparsely populated area are the
villages of Clayton (Pop: 1,970) and Dexter (Pop: 1,061).

Oswegatchie River
The Oswegatchie River drains 430,000 hectares (1,063,000 acres) in north-
central New York. The mean annual discharge into the St. Lawrence River is
81.4 m /s (2874 cfs). Major tributaries to the Oswegatchie are the Indian River
and the West Branch. Many natural lakes exist in the headwaters area and the river
itself has been extensively dammed for hydroelectric generation. The topography
varies from flat and rolling near the mouth to mountainous in the upper reaches.
Runoff is high but streamflow is greatly regulated by the many impoundments along
the river. Roughly 80% of the area is forested, 15% is agriculturized, and 5% is
in urban uses. Bedrock consists of igneous and metamorphic rocks in the upper
mountainous reaches with carbonates and sandstones underlying the area near the
mouth. Surface deposits in the lower reaches are mostly silt and clay lake bed
sediments, while the upper drainage area is mainly exposed bedrock with some
glacial till. The local economy is based on forestry, dairying and mining (iron,
talc, zinc, and silver). Paper mills and dairy plants contribute significantly
to tributary wastewater loads. The major population centers, Ogdensburg
(Pop.: 14,554) and Gouverneur (Pop.: 4,574) also contribute wastewater from muni-
cipal and industrial sources.

Grass-Raquette-St. Regis Complex
The Grass-Raquette-St. Regis complex covers an area of 823,000 hectares
(2,033,600 acres) in northcentral New York. The major tributaries and their mean
annual discharges are the Grass River (32.6 m /s, 1150 cfs), the Raquette River
(61.7 m /s, 2180 cfs) and the St. Regis River (39.4 m /s, 1391 cfs). The flow
of the Grass River is increased by diversion of a part of the St. Lawrence via
the Massena Power Canal at Massena. Major tributaries to the Grass River are
Harrison Creek and the Little River; to the Raquette are the Bog River and Jordan
River; and to the St. Regis are the Deer River and the East and West Branches of
the St. Regis. All three major rivers have their headwaters in the mountainous
Adirondack region and flow northerly onto the flat to rolling plain along the
St. Lawrence River. There are many natural lakes and man made impoundments in
the upper reaches; the Raquette River is especially heavily utilized for hydro-
electric generation. Many wetlands are present in the mountainous areas. Approxi-
mately 75% of the region is forested, 20% is devoted to agriculture and 5% is in
urban usage. Bedrock is composed for the largest part of crystalline rocks with
a smaller area along the St. Lawrence River underlain by sandstone and carbonates.
Surficial deposits consist of silt and clay in the lower reaches and areas of
both exposed bedrock and glacial outwash in the southern portion. The economy
is based on mining, metals production, dairying, and forestry. Aluminum production
utilizes much of the electric power generated within the region. The Grass River
receives municipal effluent from Conton (Pop.: 6,398) and Massena (Pop.: 14,042)
and industrial wastes from aluminum plants, dairy processing plants, and ore re-
fineries. The Raquette River is subject to industrial and municipal wastewater
loadings from the Potsdam (Pop.: 9,985), Norwood (Pop.: 2,098), and Tupper Lake
(Pop.: 4,854) areas. The St. Regis River receives only small amounts of municipal
effluent but receives significant discharges from paper mills and food processing
plants.

Saginaw River
The Saginaw River drains an area of 1,617,000 hectares (3,995,000 acres).
The area is located in the east central portion of Michigan's Lower Peninsula.
Generally only maximum flows are measured at the river mouth of the Saginaw
River. Major tributaries to the Saginaw River are the Cass River, Flint River,
Shiawassee River, and the Tittabawassee River. The topography is mostly flat,
with rolling hills in the west. Approximately 25 percent of the area is forested,
about 60 percent is agriculturized, and about 10 percent is urbanized. The bed-
rock is composed mostly of limestone. The soil is generally composed of a silt
and clay combination with glacial till in some areas. The economy is based
heavily on manufacturing with some agriculture and mining of natural resources
such as oil, sand and gravel, salt, peat, and clay. The cities of Saginaw, Bay
City and Flint are all heavy industrial areas and subject the surface waters to
heavy wastewater loadings. A large number of municipalities and industries use
the surface waters of ths Saginaw River and its tributaries for waste assimilation.
The cities of Flint (Pop.: 193,317), Saginaw (Pop.: 91,849), Bay City (Pop.:
49,449), Midland (Pop.: 35,176), Mount Pleasant (Pop.: 20,504), and Owosso
(Pop.: 17,179) are the most highly developed urban centers in this area.
