The Navasota Watershed (HUC 12070103) covers approximately 1,458 square miles in east-central Texas. The region is characterized by a humid subtropical climate with hot summers and mild winters. Precipitation is generally distributed evenly throughout the year, with an average annual rainfall of 48 inches. The watershed is drained by several major streams, including the Navasota River, which flows into the Brazos River. The primary land use in the area is agriculture, with livestock grazing and crop cultivation being the dominant activities. The watershed is also home to several reservoirs, including Lake Conroe, Gibbons Creek Reservoir, and Somerville Lake. These reservoirs serve as important sources of drinking water, hydroelectric power, and recreational activities. Climate change is likely to have a significant impact on the watershed, with increased temperatures and more frequent extreme weather events expected in the coming years.
