Dilution water, low in macronutrients, was added to Moses Lake on three occasions in 1977 and once in 1978 during the spring-summer period. The addition resulted in reducing the annual average inflow concentration of phosphorus from about 130-140 micrograms/l to 100 micrograms/l. The water exchange rate in Parker Horn, which is 8% of the lake volume, increased about 1%/day normally to 7 and 11%/day for the May-September period in 1977 and 1978, respectively. Improvements in lake water quality, compared to values from 1969-70, were rather good with greater reductions in algal biomass.
