In Kansas, analytical methods have been used to determine whether additional groundwater is available for appropriation. For the Lower Republican River Basin and Belleville Formation in Kansas, the Jenkins method (a graphical approach based on the Glover-Balmer equations; Jenkins, 1968) has been used to estimate the cumulative volume of stream depletion that occurs in one year after the day pumping begins for an application to appropriate groundwater to see whether the new appropriation is acceptable (Kansas Department of Agriculture, 2010). The Glover and Balmer method has been employed in Colorado to evaluate the current and projected stream depletion impacts of water pumped and discharged during coalbed methane production (Papadopulos and Associates and Colorado Geological Survey, 2007).
