Abstract:

This study was begun in 1982 to assist the Bear River Commission in their statutory obligation of determining a duty of water under the Bear River compact. The study involved installing 7 non-weighing lysimeters in three states for the determination of meadow evapotranspiration (ET). At all study sites, climatic factors are measured by the use of Campbell Scientific CR21 automated weather stations. Study sites are south of Evanston, Wyoming at an elevation of 7550 feet, near Randolph, Utah at an elevation of 6280 feet and near Bear Lake close to Montpelier, Idaho at an elevation of 5930 feet. The 1000 foot difference in elevation lead to marked differences in plant composition and other factors in the meadows.
