Abstract

A preliminary study of some ecological factors of Lake East Okoboji was made in the period June 1960- June 1961. Chemical analyses were conducted to determine phenolphthalein alkalinity, total alkalinity, calcium hardness, total hardness, chloride, sulfate, pH, dissolved oxygen, iron, phosphate, nitrate, and silica. Collections of diatoms were made concurrently with the chemical analyses. Lake East Okoboji was found to be an alkaline, shallow, non-stratified, moderately hard water lake. A large spring and fall bloom of diatoms occurred, with a dense blue-green algal bloom in mid-summer.
