| Description | 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 interstitital 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 Nutrient and lake waters. Variations in lake and intersitital waters frequently, but not always, exhibited inverse relationships. The larger fluctuations appeared to correlate with density of A. flos-aquae. Although strong evidence of biological uptake of sedimentary nutrients was found, dredging of the lake would probably not be effective as a restorative measure because of the high nutrient concentrations present at depth in the sediment. | en |
