Welch, E. THE DILUTION/FLUSHING TECHNIQUE IN LAKE RESTORATION. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-81/016.

Description:

Dilution/flushing has been documented as an effective restoration technique for Moses and Green Lakes in Washington State. The dilution water added in both lakes was low in nitrogen and phosphorus content relative to the lake or normal input water. Consequently, lake nutrient content dropped predictably. Dilution or flushing rates were about ten times normal during the spring-summer periods in Moses Lake and three times normal on an annual basis in Green Lake. Improvement in quality (nutrients, algae, and transparency) was on the order of 50 percent in Moses Lake and even greater in Green Lake.
