Dilution with low-nutrient Columbia River Water (CRW) has markedly improved Moses Lake quality for 42 years. There were two phases of CRW volume input, which proportionately lowered total phosphorus (TP). Initially, spring-summer inputs averaged 130

Large blooms of cyanobacteria, primarily Aphanizomenon flos-aquae, are linked to poor water quality in Upper Klamath Lake, Oregon. High pH and high un-ionized ammonia concentrations are associated with the blooms when algae are actively growing, foll

Moses Lake has received dilution water in 9 of 10 years since treatment began in 1977. The average input for those years was 143 ± 79 × 106m3/yr over 93 days, which represents flushing rates of about 13 percent/day for Parker Horn where the dilutio

Environmental factors associated with the occurrence of toxic cyanobacterial blooms and toxin production were investigated during the summers of 1994 and 1995 in Steilacoom Lake, Washington. A pronounced and prolonged toxic bloom of Microcystis aerug
