Basis for Assessment

Comments of DNR Wildlife Biologist indicate the wetland is periodically used for fish rearing purposes and piscicides are used.   These chemicals may be detrimental to non-target aquatic species.   Based on the biologist's recommendation, the use support status was changed from FS to FST to reflect potential adverse impacts on the native wetland community.
