John Day Basin

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.

TMDL approved by the Environmental Protection Agency on Dec. 17, 2010.
