Restoration Analysis of Wapato Lake, Tacoma, Washington: An Evaluation of Dilution and Stormwater Control as Urban Lake Restoration Techniques

摘要

Stormwater runoff to Wapato Lake, Washington, brings fecal bacteria, heavy metals, oil and grease, and nutrient loading. Stormwater managment (diversion and retention), and dilution with nutrient-poor Green River water should reduce phosphorus and nitrogen loading. Recommendations made are: dredging, drawdown, beach renovation, and storm drain cleaning.
