The Little Cypress watershed (HUC 11140307) covers approximately 120 square miles in southeastern Texas. The area experiences a humid subtropical climate with hot summers and mild winters. Precipitation averages around 50 inches per year, mostly in the form of rain. The watershed is home to several streams and lakes, including Little Cypress Creek and Lake Sam Rayburn. The Little Cypress watershed is not known for significant snowpack, as the area typically does not receive high amounts of snowfall. Reservoir constituents in the area include sediment, nutrients, and organic matter. In recent years, the area has experienced increasing water demand due to population growth and industrial development. Climate change is also a concern in the region, with rising temperatures and changes in precipitation patterns potentially impacting the watershed's hydrology.
