Abstract
The Federal Clean Water Act requires the Iowa Department of Natural Resources (IDNR) to develop a total maximum daily load (TMDL) for waters that have been identified on the state’s 303(d) list as impaired by a pollutant. Little Spirit Lake has been identified as impaired by algae and turbidity. The purpose of these TMDLs for Little Spirit Lake is to calculate the maximum allowable nutrient loading for the lake associated with algae and turbidity levels that will meet water quality standards. This document consists of TMDLs for algae and turbidity designed to provide Little Spirit Lake water quality that fully supports its designated uses. Phosphorus, which is related through the Trophic State Index (TSI) to chlorophyll and Secchi depth, is targeted to address the algae and turbidity impairments.
