TMDL title: John Day Basin TMDL and WQMP
Water quality limited parameters: ammonia toxicity, aquatic weeds or algae, E. coli, fecal coliform, nitrate, pH, sedimentation, temperature, turbidity
Pollutants: ammonia nitrogen, heat, E. coli, nitrate, total suspended solids, turbidity
Status: EPA approved on Dec. 17, 2010
Project overview
Many streams and rivers of the John Day Basin do not meet water quality standards during part or all of the year. DEQ has identified several water quality concerns in the
basin, including high temperature and bacteria levels, low oxygen concentrations and impaired biological conditions.
