REGION | WATER BODY NAME | WATER TYPE | WATERSHED* CALWATER / USGS HUC | POLLUTANT POTENTIAL SOURCES Relevant Notes | ESTIMATED AREA ASSESSED | FIRST YEAR LISTED | ADDRESSED BY** | USEPA TMDL APPROVAL DATE
6 | Indian Creek Reservoir | Lake & Reservoir | 63220010 / 1.60502e | Phosphorus Erosion/Siltation Flow Regulation/Modification Internal Nutrient Cycling (primarily lakes) Pasture Grazing-Riparian and/or Upland Wastewater | 164 Acres | 2002 | B | 2003
| Reservoir is eutrophic. Most significant source of nutrient loading is release of phosphorus from sediment. The USEPA approved the TMDL in 2003. Reductions in internal phosphorus loading from the sediment are expected to ameliorate other problems associated with eutrophication.
6 | Squaw Creek | River & Stream | 63520011 / 16050102 | Sedimentation/Siltation Construction/Land Development Drainage/Filling Of Wetlands Highway Maintenance and Runoff Hydromodification Natural Sources Nonpoint Source Other Urban Runoff Recreational and Tourism Activities (non-boating) | 5.8 Miles | 1998 | B | 2007
