Meyers Lake IA 02-CED-463

Assessment Comments

Monitoring conducted by ISU for Clean Lakes Classification study (1994).

Basis for Assessment

Results of monitoring conducted in 1992 for the 1994 ISU Clean Lakes Classification study show that total-P and TSS are at or better than average levels for all SPOL lakes in Iowa sampled between 1990 and 1992.   Average levels of chl-a and secchi depth were worse than overall averages and approached 1 SD from the overall mean.   Based on this information, assessment for the 1992 was upgraded from PS to FST for the 1994 report.   Although designated for swimmable uses, Bachmann et al.  (1994) reported swimming use as zero; thus, swimmable uses were not assessed.  Lake does not have problems with fishkills.   Lake has one of the lowest sedimentation rates (0.2 cm/yr) and longest life expects.  (1113 years) of any lake identified as an SPO impoundment in Iowa.   Urban runoff was identified as a source of impairment in the 1992 report.
