Basis for Assessment
Lake will remain assessed as PS for the 1994 report. Lake has one of the higest sedimentation rates (8.2 cm/yr) and shortest life expectancies (27 years) of any SPOL in Iowa. Level of swimming use reported by Bachmann et al. (1994) is relatively low, but is not in the lowest 10% of SPO impoundments sampled in 1990 and 1992. Levels of total-P, TSS, and secchi in worst 10% of 86 SPO impoundments sampled in 90 & 92.
