Lawtonka Reservoir Phase 1 Diagnostic/Feasibility Study

摘要

The study was designed to identify the cause or causes of the persistent pollution problem occurring in Lawtonka Reservoir. Lawtonka Reservoir is eutrophic and develops an anaerobic hypolimnion in the near dam area during the months of July, August and September. Phosphorus is the limiting macronutrient. Leakage of water through the road bed into School House Slough from the small pond to its east should be stopped. Pumping should be minimized when the concentration of Total Phosphorus in the pipeline exceeds that in the reservoir. Sampling should be undertaken to confirm and evaluate the persistence and magnitude of the mercury problem found at Robinson's Landing.
