Draft Palisades Subbasin Water Quality Improvement Plan

Accepting Comments from August 31, 2018 to October 1, 2018

DEQ is seeking public comment on proposed plans to improve water quality in various water bodies in the Palisades subbasin in eastern Idaho.

Certain water bodies in the Palisades subbasin have been identified as impaired by sediment, E. coli bacteria, and elevated temperatures.

Excess sediment in surface waters can alter flow patterns and negatively impact aquatic habitat and cold water aquatic life. Excess bacteria can degrade recreational use of surface waters and, if ingested, cause gastrointestinal illnesses. Temperature is a key factor in the health of fish and other coldwater organisms. Recent analyses of water quality data demonstrated that E. coli levels exceed water quality standards in Rainey Creek and sediment and temperatures are above recommended levels in a number of streams in the subbasin.

The Palisades Subbasin: 2018 Total Maximum Daily Load and Five-Year Review proposes to establish total maximum daily loads (TMDLs) to reduce sediment and E. coli bacteria and lower water temperature in the subbasin.
