Description To better manage water quality, a total maximum daily load assessment for Moses Lake and its major sources was made based on a review of data from previous studies of the lake. An in-lake total phosphorus (TP) criterion was proposed based on the water quality target established in 1978 to reduce the seasonal, in-lake TP concentration to 50 ug/L. Although this TP value exceeds the lake nutrient criterion established in Washington State water quality standards for surface water, it is recommended that 50 ug/L TP be the new criterion for Moses Lake.
