One of ten major river authorities in Texas, our mission is to develop, conserve, and protect the water resources of the San Jacinto River watershed.  We accomplish our mission through the following four operational divisions:

Lake Conroe Division – Located at the Lake Conroe Dam, seven miles west of the City of Conroe, the Lake Conroe Division’s primary function is the operation and maintenance of the dam, spillway structure, and service outlet at Lake Conroe.  In addition, this division handles inspection and enforcement functions related to on-site sewage systems around Lake Conroe.  To maintain the safety of Lake Conroe for navigation and recreation, and to manage the construction of permanent structures on the lake, the Lake Conroe Division also administers a permit program for residential docks, piers, marinas, commercial operations, and marine sanitation facilities.  Lake Conroe was completed by the SJRA in 1973 as a water supply reservoir through a joint venture with the City of Houston, which owns two-thirds of the water rights in the reservoir.

Woodlands Division – Located in southern Montgomery County, the Woodlands Division provides wholesale water supply and wastewater treatment services to the 90,000-person community of The Woodlands Township. To provide these services, the SJRA operates three regional wastewater treatment facilities with numerous pump stations, 40 water wells, several elevated and ground storage tanks, and miles of collection and distribution lines.  The Woodlands Division serves as the wholesaler to the 12 municipal utility districts that provide retail services within The Woodlands.

Highlands Division – Located in East Harris County, the Highlands Division delivers raw water from Lake Houston through an extensive 35-mile system of canals and a 1400-acre reservoir for delivery to customers such as Exxon Mobil, Chevron Phillips Chemical Company, and a number of other industrial, municipal, and agricultural customers pursuant to long-term water supply contracts.

GRP Division – Located at the Lake Conroe Dam, the Groundwater Reduction Plan Division is responsible for implementing a countywide groundwater reduction program that will meet the requirements of the Lone Star Groundwater Conservation District and ensure reliable long-term water supplies for all of Montgomery County.  The GRP Division will seek to develop a number of alternative water strategies including conservation, reuse of treated wastewater effluent, groundwater from the Catahoula Aquifer, and surface water from Lake Conroe.  The surface water strategy will include the design, construction, operation, maintenance, and administration of a water treatment plant and transmission lines that will withdraw raw surface water from Lake Conroe, treat it to meet or exceed drinking water standards, and then transmit it to customer cities and utilities within Montgomery County.   

As part of an ongoing Habitat Enhancement Program for Lake Conroe, the Texas Parks and Wildlife Department and the San Jacinto River Authority have partnered with other local entities to place over 500 fish attractors in Lake Conroe.

Partners in the program include the US Army Corp of Engineers, Texas Black Bass Unlimited, Seven Coves Bass Club, and the Bass Anglers Sportsman's Society.
