Upper Klamath Lake, a very large, shallow lake in south-central Oregon, has a history of nuisance blue-green algae blooms, predominantly Aphanizomenon flos-aquae. Lake water and sediment interstitial water chemistry were monitored during 1968 and 1969, and for a short time in 1970. Nutrient concentrations in interstitial water of sediment exposed to direct agricultural drainage were several orders of magnitude greater than in cases where sediments were not so located. Nutrient concentrations showed considerable seasonal variation in both interstitial and lake waters. Variations in lake and interstitial waters frequently, but not always, exhibited inverse relationships. The larger fluctuations appeared to correlate with density of A. flos-aquae.
