Description:
Lake Notasha, near the crest of the Oregon Cascade mountain range, is the most dilute lake known. he measured conductivity during two visits was 1.3 and 1.6 uS cm-1, with a sum of base cations of 9 and 18 ueq L-1; bicarbonate was the dominant anion. ost of the cations in the lake can be accounted for by evapoconcentration of precipitation although input of weathering products cannot be excluded as a source. he topographic watershed has a mixed coniferous forest, but the hydrologic setting of the lake apparently minimizes watershed contributions. his feature makes lakes such as Notasha appropriate receptors for monitoring atmospheric contaminants.
