Lake Conroe-Lake Houston Joint Reservoir Operations Study

Study Description

The City of Houston is currently performing a project to add new spillway gates to increase the controlled release capacity of the Lake Houston dam. The goal of this Joint Reservoir Operations Study is to determine the most efficient and safe operation of Lake Conroe and Lake Houston in series once the new gates are installed. The study will evaluate the feasibility of prereleases including impacts on water supply. The study will also develop a forecasting tool for Lake Houston and support development of the gate operations policy for the proposed Lake Houston dam gates.

Funding

The cost of the study is estimated at up to $1 million. Fifty percent of the cost (up to $500,000) will be provided by grant funds from the Texas Water Development Board Flood Infrastructure Fund (FIF) grant program. City of Houston and City of Humble have together agreed to fund the remaining fifty percent local match (up to $500,000). SJRA is providing in-kind services to reduce the local match amount to be funded by the Partners.
