A Study Of Phytoplankton In Spring Meadow Lake Helena, Montana
The types of phytoplankton in Spring Meadow Lake were observed and their growth patterns recorded over a 4-month period. Algal growth peaked in mid-August and was dominated by genera of green algae (Chlorophyta). The lake did not show definite thermal stratification. The lake's nutrient situation can be described as being phosphorous-limiting early in the study period and shifting toward nitrogen-limiting during the mid-August peak.
