Data Report
I. INTRODUCTION
The Curwensville Reservoir is located on the West Branch Susquehanna
River near the town of Curwensville (Clearfield County) in north-central
Pennsylvania. The conservation (recreation) pool covers 790 acres at
elevation 1162 feet above mean sea level. The net storage capacity of
the reservoir for flood control purposes is 119,300 acre-feet at the
spillway elevation of 1228 feet MSL and the flood pool covers 3668 acres.
The impoundment was constructed and is operated by the U. S. Army
Corps of Engineers, Baltimore District, as a part of a comprehensive
plan for flood control, recreation and water quality control in the West
Branch Susquehanna River Basin. Water quality control is necessary owing
to acid mine pollution from abandoned coal mines upstream from the dam.
This pollution has severely degraded water quality in the West Branch
between Karthaus and Lock Haven. At Lock Haven, the river receives
alkaline waters from Bald Eagle Creek which helps neutralize the acid-
polluted waters from upstream. However, during low-flow periods, this
neutralizing effect is lost and fish kills have occurred. To counteract
this condition, the Curwensville Reservoir is operated to store temporarily
these acid waters during low flow periods to prevent or minimize the

severity of fish kills downstream from Lock Haven.
II.	PURPOSE
In response to a request from the Baltimore District, U. S. Army
Corps of Engineers, the Federal Water Quality Administration initiated
a sampling program to monitor changes in water quality in the Curwensville
Reservoir after the pool had filled. This report contains the results
of these findings from 1966 to early 19&9*
III.	SCOPE
The scope of the sampling program was limited to acid mine drainage
parameters including conductivity, pH, acidity, net alkalinity, total
iron, sulfate, manganese and aluminum. In addition, calcium and magnesium
determinations were made to evaluate total hardness of the water.
A total of six stations were sampled upstream from the damsit'e as
shown in Fig. 1. Five of these stations were located in the impoundment
with the sixth station (Station I) being located on the West Branch Sus-
quehanna River upstream from the back-water effects of the impoundment.
Two additional stations were located downstream from the damsite. The
first site was located at the discharge conduit from the impoundment and
the second located at the U. S. Geological Survey stream gage site at
Curwensville, O.85 mile downstream from the damsite.

-------
3.
IV. PROCEDURE
Field collection of the samples were made by the U. S. Army Corps
of Engineer personnel using standard field sampling techniques outlined
by the Federal Water Quality Administration. Laboratory analyses were
performed by F.W.Q.A. chemists using methods given in the publication
"Standard Methods for the Examination of Water and Wastewater," APHA,
AWWA, WPCF, 12th ed., 1965-
