Basis for Assessment

Used assessments of support of the Class A (primary contact) uses (=PS), the Class B(LW) aquatic life uses (=PS), and fish consumption uses (=FST) developed for the 1994 report.   Information from the report prepared by the Easter Lake Task Force (1995, Snyder & Associates and Dunbar/Jones Partnership) supports these assessments:  sediment eroded from the watershed and deposited in the lake has reduced surface area from 220 acres in 1960 to 170 acres currently.   Reductions in useable surface area and declines in water quality have contributed to an estimated 55% drop in beach use.   The Easter Lake Task Force was formed to develop a program for preservation and enhancement of water quality in the lake and its tributaries.
