The Elm Fork Red Watershed (HUC 11120304) is located in north-central Texas and covers an area of approximately 1,372 square miles. The hydrology of the watershed is characterized by a mix of urban and agricultural land uses, with numerous small streams and channels that ultimately drain into Lake Lewisville. The watershed receives intermittent rainfall throughout the year, with peak precipitation occurring in the spring and fall months. Snowfall is rare in this region of Texas, and snowpack does not significantly contribute to surface water resources. Surface water quality in the watershed is generally good, although recent studies have identified elevated levels of nutrients and bacteria in some streams and tributaries. Climate trends in the region suggest that temperatures are becoming warmer and precipitation patterns are becoming more variable, which may impact water availability and quality in the future.
