The South Corpus Christi Bay watershed covers an area of approximately 880 square miles in Southern Texas. The hydrology of the region is largely influenced by the Nueces River, which flows through the area and eventually empties into the bay. Precipitation in the region is generally low, with an average of around 30 inches per year. Snow is rare in this part of Texas. Surface water in the watershed includes several lakes and reservoirs, including Lake Corpus Christi and Choke Canyon Reservoir, which are important sources of drinking water for the region. The reservoirs also provide recreational opportunities for locals and visitors. The climatic trend in the region is generally warm and humid, with high temperatures averaging around 90°F in the summer months. The area is also prone to tropical storms and hurricanes, with the most recent major hurricane, Harvey, causing significant damage to the region in 2017.
