Basis for Assessment
Lake does have better than average water quality: monitoring in 1990 shows that averages of secchi depth, chl-a, total-P, and TSS are all better than overall means for the 116 SPOLs sampled in 1990 and 1992; all these averages are near the better end of the overall mean +/- 1 SD. Thus, this lake, despite being relatively shallow and not stratified, has water quality well above average for Iowa's SPOLs. However, the fishable and swimmable uses of this lake were assessed as PS at recommendation of DNR Fisheries that feel the lake is impaired by nuisance growths of rooted aquatic vegetation.
