Paired samples taken from 100 lakes during July of 1980 were examined for desmids and analyzed chemically. The lakes lie in an area roughly one hundred km by fifty km within northeastern Pennsylvania. Elevations above mean sea level range from 289 m to 624 m. Harveys Lake, with an area of 280 hectares, is the largest natural lake, by volume, in the state. Lakes Henry and Ladore also exceed 100 hectares but the other 97 were smaller. From each lake two samples were taken in the littoral zone close to vascular aquatic plants. Simple linear regression analyses comparing desmids with pH, conductivity, alkalinity, calcium, magnesium, sodium, and potassium indicated very little statistical correlation between numbers of species and any single chemical factor. Stepwise regression for pairs of chemical values produced highest R-square for pH and magnesium but not positively significant. 40 references, 4 tables.
