Otter Creek is impaired due to degraded habitat because of excessive sediment loading from surrounding agricultural lands to the Creek. Otter Creek is currently not meeting the applicable narrative water quality standard (WQS) that prohibits objectionable deposits on the shore or in the bed of a water in amounts that interfere with public rights in the water. To address the degraded habitat impairments, Wisconsin Department of Natural Resources (WDNR) determined that sediment, specifically TSS, is the pollutant that must be addressed to attain designated uses and meet WQS.
