Paired samples taken from 100 lakes during July, 1980, were examined for desmids and anlayzed chemically. 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 (0. 21139) but not positively significant.
