Summary

To quantify seepage losses from the Medina and Diversion Lake system that provide recharge to the Edwards aquifer and upper zone of the Trinity aquifer, water budgets were analyzed for the period during March 2, 1955–October 6, 2022, and over a range of stages in Medina Lake. In the water-budget analysis, the applicable components of the hydrologic cycle pertaining to Medina and Diversion Lakes were evaluated. The water-budget equation incorporates measurable terms of inflow and outflow to solve for (or otherwise scientifically estimate) unknown gains or losses, or both, from a lake or lake system. The measurable terms include precipitation, evaporation, surface water inflow and outflow, and change in lake storage. The solution to [...]

Purpose

The data were collected and then analyzed by using a weighted least-squares regression analysis to determine the relation between Medina Lake stage and seepage losses (recharge) from the Medina and Diversion Lake system which provide recharge to the Edwards aquifer and upper zone of the Trinity aquifer. The weighted least-squares regression analysis is described in detail in the companion larger work citation for this data release.
