Fighting Creek (aka Bellgrove Creek)

  • Drains a 6.1 mile2

watershed

  • n the southwest side of

Coeur d’Alene Lake

  • Part of the watershed is

within Coeur d’Alene Tribal boundaries

  • Currently listed on Idaho’s

2008 Integrated Report as impaired for E. coli due to violations of Water Quality Standards in 2005 and 2007

  • In 2008 BURP scores

conclude beneficial uses are not supported
