Blue Marsh Lake Project Water Quality Data Report (RCS-DAEN-CWE-15).

Blue Marsh Dam and Reservoir is located on Tulpehocken Creek, a tributary of the Schuylkill River in Berks County about six miles northwest of Reading, Pa. The primary purposes of the project are flood control, emergency water supply storage, water quality control and recreation. The purpose of the report is to present and briefly interpret the water quality data collected to date at Blue Marsh Lake. The fecal coliform standards for swimming beaches is 200 fecal coliforms per 100 ml of sample and this was not exceeded during the current year. The report characterizes the general design areas as to land use, potential pollution sources contributing to the lake, the project itself and the relationship between potential water quality problems that may occur and possible effects of the lake on the water quality.
