Abstract

Primary production studies were conducted on an 83-acre lake in south central Iowa during the summer of 1970 and winter of 1971. Primary productivity was measured using the light­ dark bottle method. Summer values ranged from 2.74 to 6.25 grams of carbon assimilated/m2/day. This was correlated with water temperature, nitrate nitrogen, ortho phosphates, carbon dioxide, light penetration and plankton populations. Studies were continued during the winter using C14 and scintillation counting methods.
