SUMMARY
The 1967-68 survey determined total solids, chloride, and
total phosphorus loadings from thirteen south shore tributaries
to Lake Erie. The data show that large quantities of solids and
nutrients from basin tributaries are being discharged to Lake
Erie. Of the thirteen south shore tributaries sampled, the
Maumee River contributes the largest quantities of total solids
and total phosphorus. The Grand River (Ohio), because of a largo
industrial discharge near its mouth, had the largest chloride
contribution of the south shore tributaries. It is apparent from
the limited sampling program that the largest tributary loading
occurs during high flow.

INTRODUCTION
The fol levying report presents load data for thirteen south shore
tributaries discharging to Lake Erie. The report is the first of an
anticipatod annual series to be prepared by the Cleveland Program
Office of the Federal Water Pollution Control Administration, Great
Lakes Hog ion. All significant data gathered in biweekly sampling
as woll as available downstream industrial and municipal outfall data
will be included. Loadings from downstream surcharged storm and san-
itary sewers are not included.
The purpose of the reports is to better determine tributary
loadings to Lake Erie and to chronicle changes in loadings as pollu-
tion abatement measures are activated. It is not the intent to pro-
vide detailed interpretive evaluations, although the data may prove
valuable in water quality standards compliance assessment.
All water quality data of a routine nature are to be entered
into the STORET data processing system in use by the Federal Water
Pollution Control Administration.

The cooperation of the United States Department of the Interior,
Geological Survny, Water Resources Division is gratefully acknowledged
for providing strcamflow data.
PROGRAM
The Federal Water Pollution Control Administration surveillance
program on Lake Eric was initiated in response to a recommendation
by the state-federal Conference on Pollution in Lake Eric and its
Tributaries in August I9C5. A biweekly sampling program on thirteen
south shore tributaries to Lake Erie was established as part of this
surveillance program to monitor tributary loadings to Lake Erie.
Sampling locations (Figure I) were located in non-lake affected
areas with samples collected in mid-stream at mid-dep+h and identified
by mileage above the tributary mouth (Table I). Total tributary load-
ings are obtained by combining loadings at the sampling locations with
downstream outfall loadings.
The sampling program has been accomplished to date as planned
except for some winter sampling not performed due to extensive ice
coverage. The reported data cover a one-year period beginning Feb-
ruary If), l°t;7. The program is to continue indefinitely.
PARATETERS
The water quality parameters shown are those which have been
-------
F i g u re I
-------
considered up to this time as most significant in Lake Erie. These
include total solids, chlorides, and total phosphorus. To date,
sufficient data have not been available to adequately determine load-
ings of these substances to Lake Erie.
METHODS
The analytical and field methods used by the Cleveland Program
Office are given in the "Laboratory Manual, Cleveland Program Office",
available from that office of the Federal Water Pollution Control
Admi ni stration.
Momentary flow data were obtained from the nearest U. S. Depart-
ment of the Interior, Geological Survey gaging stations and prorated
to the sampling locations on the basis of drainage area. Momentary
loadings at the sampling locations (Table 2) were calculated using the
momentary flow and the parameter concentration.
Average daily tributary loadings at sampling locations (Table 4)
were calculated by dividing the sum of the momentary loadings by the
sum of the momentary flows and multiplying by the average flow for the
period of record at the nearest gaging station.
Tributary loadings to Lake Erie (TaWe 6) have been obtained by
summing the loading at the sampling location and all known major down-
stream loadings from outfalls (Table 5).
DISCUSSION OF ANALYTICAL DATA
The data obtained in the 1967-68 survey provided a limited basis
for the determination of tributary loadings to Lake Erie. The reader
is cautioned to note that all loadings are subject to revision with
the accumulation of additional sampling, outfall and overflow data.
Widely variable flow conditions were encountered at the times of
sampling (Table 2). Generally, concentrations did not show consistent
changes with changes in flow, however major loadings did occur during
high discharges. The highest single concentration of total solids and
chloride was noted in the Grand River (Table 3). The highest phosphorus
concentration noted was in the Cuyahoga River.
The summary tabulation of tributary loadings at the sampling lo-
cations (Table 4) shows the Maumee River, with the greatest flow of the
tributaries sampled, as having the largest loading contribution. The
Ashtabula River, with the smallest flow, has the smallest contribution
of total solids and chlorides. Total phosphorus loading was least in
Conneaut Creek.
Since the sampling locations are several miles above the mouth of
the tributaries, downstream sources must be considered in determining
-------
total loadings. MajDP known downstream sources in each of the trib-
utaries have been listed (Table 5). Municipal loadings were estimated
and industrial loadings were calculated from available data. In the
-Grand and Ashtabula Rivers downstream inputs far exceeded the loadings
at the sampling locations. However, in the other tributaries, down-
stream inputs were less significant.
Tabulation of tributary loadings to Lake Erie (sampling location
plus downstream data, Table 6) shows the Maumee River as contributing
the largest amount of total solids and total phosphorus. The Grand
River, because of a large industrial discharge near its mouth, is the
largest contributor of chlorides. The smallest contribution of total
solids was noted in Conneaut Creek. The smallest chloride loading
was in the Huron River and the smallest phosphorus loading was In
the Ashtabula River.
Several factors should be considered when evaluating the adequacy
of the data presented. The limited frequency of sample collection,
particularly during periods of high flow, could bias the data. Sed-
imentation of the constituents through chemical, biological, and
physical means, could result in low tributary loading values. The
loadings determined from the sampling program do not include bed load.
During high flows, bed load transport to the lake is probably high.
Downstream industrial and municipal outfall data are not complete,
but will be updated as information becomes available. Contributions
from untold numbers of combined sewer and storm water overflows exist-
ing in the lower reaches of many tributaries also may be significant
but are not included in the data. The loading data presented is thus
very conservative.
