Summary
Completed in 1964, this Earth-type dam stands at 15 feet high and spans a length of 800 feet, with a storage capacity of 138 acre-feet. The dam is situated on Salt Creek and is under the jurisdiction of the Galveston District, but is not regulated by the state.
Despite being classified as having a high risk potential, Cook Lake Dam is currently in a not rated condition assessment, with no reported inspection date. The dam does not have a spillway and features one outlet gate. With a primary purpose of water supply, the dam plays a vital role in supporting the local community's water needs. Although there are no associated structures or locks, the dam's presence on Salt Creek ensures a reliable water source for the area.
Water resource and climate enthusiasts will appreciate the significance of Cook Lake Dam in providing essential water supply services to the region. With a history dating back to 1964, this Earth-type dam continues to be a key infrastructure for water management on Salt Creek. While it is important to note the high risk potential associated with the dam, its operational status and lack of recent inspection data may warrant closer attention to ensure its continued safety and functionality for the community.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
