Badger Lake IA 04-UDM-1291

Assessment Comments

Basis for Assessment

Both fishable and swimmable uses were assessed as PS for the 1994 report for the following reasons:  (1) BPJ of DNR staff that report complaints from the local public regarding WQ problems and unpleasant odor at Badger Lake; (2) results of monitoring show that average levels of chl-a, total-P, and TSS are worse than overall averages for the 86 SPO impoundments sampled in 1990 and 1992, but all are within +/- 1 SD of the overall averages; average level of secchi depth is approx equal to the overall average; (3) estimate of swimming use in Bachmann et al.  (1994) is in the lowest 10% of the 61 SPO impoundments with data for swimming use; this low number in a lake near a large population center with few other swimmable waters nearby suggests an impairment; (4) the lakes sedimentation rate (11.6 cm/yr) and life expectancy (17 years) are in the worst 10% of 86 the SPO impoundments.
