Easter Lake IA 04-LDM-1024

Assessment Comments

Assessment is based on results of (1) ISU lake monitoring, (2) surveys by IDNR Fisheries Bureau, and (3) results of U.S. EPA/IDNR fish tissue monitoring

Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses were considered "not assessed."  Continue to assess support of the Class B(LW) aquatic life uses as "partially supported."  Fish consumption uses were 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).   The previous assessment of the Class B(LW) aquatic life uses ("partially supported") was reviewed and approved by the DNR Fisheries Bureau in 2000.   The DNR Fisheries Bureau added that some improvement has occurred with regard to reductions of urban nonpoint sources to this lake due to city actions, but the general trend remains "declining."  Fish consumption uses remain assessed as "fully supported" based on results of EPA/DNR fish tissue (RAFT) monitoring in 1997 (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.
