| Study Name | Nisqually River Basin Fecal Coliform Bacteria and Dissolved Oxygen Total Maximum Daily Load Study |
| EIM Data Entry Review Status | Reviewed |
| Study Type | Total Maximum Daily Load (TMDL) development |
| Study Purpose | During 2002 and 2003, the Department of Ecology conducted a Total Maximum Daily Load (TMDL) study for fecal coliform bacteria in the Nisqually River, the Nisqually Reach of Puget Sound, Ohop Creek, Red Salmon Creek, and McAllister Creek. A TMDL analysis was also conducted for dissolved oxygen in McAllister Creek. |

| Study QA Assessment Level | Level 4: Data Verified and Assessed for Usability in a Formal Study Report |
| Study Result Description | Results showed that the Nisqually River and much of Nisqually Reach met fecal coliform water quality standards. Ohop, McAllister, and Red Salmon creeks did not meet standards. Best management practices are recommended for bacteria reduction.
Low dissolved oxygen levels found in McAllister Creek were determined to be largely due to natural conditions |
