Basis for Assessment

Bachmann et al. (1994) shows that Badger Creek L. is not used for swimming; thus, this use was not assessed. Fishable uses were assessed as PS for the following reasons: (1) results of monitoring in 1992 show that averages of secchi depth, chl-a, and total-P are approx. equal to, or worse than, overall averages for the 116 SPOLs sampled in 1990 and 1992; the average level of TSS was better than the overall mean for SPOLs; (2) Bachmann et al. (1994) report relatively high use numbers for fishing at the lake; (3) lake does not have fishkill problems; (4) 95 percent of watershed is in approved soil conservation practices; (5) lake has a moderately low sedimentation rate and a moderately long life expectancy (122 years). DNR Fisheries believes that the rel. large watershed:lake area ratio impairs uses due to high levels of sediment delivered to the lake.
