Implications of Stream Impoundment on Yegua Creek, Texas

Abstract

Yegua Creek, south-central Texas, has been modified by the construction of Somerville Dam. Data are presented in this article that demonstrate changes in the characteristics of the stream. An analysis of discharge indicates that annual discharge downstream from the dam is statistically the same when pre-dam and post-dam discharge is compared. Spring high flows are decreased and early autumn low discharges are increased after dam construction. Since the construction of the dam, riparian vegetation has increased in proximity to the channel while for areas on either side of the stream the area of woodland vegetation has decreased. Increased riparian vegetation may be related to less variability in discharge, especially in the drier late summer.
