Kent Park Lake IA 02-IOW-694

Assessment Comments

Assessment is based on results ofISU monitoring and surveys of DNR Fisheries Bureau.

Basis for Assessment

Both fishable and swimmable uses were assessed as FST for the following reasons:  (1) BPJ of DNR Fisheries; (2) results of ISU monitoring show that average levels of secchi depth, total-P, chl-a, and TSS were approximately equal to, or better than, overall averages for the 116 SPOLs sampled in 1990 and 1992; (3) according to Bachmann et al.  (1994), lake has moderately high sedimentation rate (3.1 cm/yr) and moderately low life expectancy (70 years); (4) they also report moderately high numbers for swimming and fishing uses; (5) fishkills are not a problem; (6) according to Bachmann et al.  (1994), "nuisance algal blooms are minimal."  Thus, lake has approximately average water quality for SPOLs in Iowa and is threatened by sediment delivered to the lake in NPS runoff.
