Lake Meyer IA 01-TRK-158
Winneshiek County S34T97NR9W 3 mi SW of Calmar.
Assessment Comments
Assessment is based on (1) surveys by DNR Fisheries and (2) results of fish tissue (RAFT) monitoring in 1994. See attached document for details.
Basis for Assessment
SUMMARY: The Class A (primary contact recreation) uses remained "not assessed." Continue to assess support of the Class B(LW) aquatic life uses as "partially supported." Fish consumption uses remained assessed as fully supported. EXPLANATION: The Class A uses were considered "not assessed" due to a lack of information on levels of indicator bacteria for this lake. The Class B(LW) uses remained assessed as "partially supported" based on the assessments developed for previous reports (see above). This assessment was reviewed and approved by the DNR Fisheries Bureau in 2000. In response to water quality problems at this lake, the Winneshiek County Soil and Water Conservation District conducted an assessment of the Lake Meyer watershed to identify priority areas for control of soil erosion. Several priority areas have been identified and landowners have been contacted. Additional funding sources are needed to implement the controls on soil erosion to improve the water quality in this lake. Fish consumption uses at this lake remain assessed as "fully supported" based on results of EPA/DNR fish tissue (RAFT) monitoring in 1994 (see assessment for the 1998 report above). This lake is scheduled to be sampled as part of the ISU/DNR lake water quality monitoring project.
