Allan Meinen Dam Reservoir Report

Last Updated: December 5, 2025

Allan Meinen Dam, located in Washington County, Texas, was completed in 1995 by the USDA NRCS and serves as a vital structure for Flood Risk Reduction along the TR-DAVIS CREEK.

Summary

This private-owned Earth dam stands at a height of 24 feet and has a normal storage capacity of 89 acre-feet, with a maximum storage of 191 acre-feet. The dam covers a surface area of 14.6 acres within a drainage area of 0.46 square miles.

Despite being classified as having a high risk potential, the dam's condition is currently not rated, with the last inspection conducted in July 2006. The absence of a spillway and the limited information on certain aspects like hazard potential and emergency action plans raise concerns about the dam's safety and management in case of extreme weather events. With no state regulatory agency overseeing its operations, there may be a need for increased monitoring and maintenance to ensure the dam's effectiveness in flood mitigation and protection of downstream areas.

Water resource and climate enthusiasts interested in the Allan Meinen Dam can observe its role in flood risk reduction and the challenges it faces in terms of regulatory oversight and emergency preparedness. The dam's location within the Galveston District and its importance in managing water flow along TR-DAVIS CREEK highlight its significance in the region's water infrastructure. As discussions continue on improving dam safety and resilience in the face of changing climate patterns, the Allan Meinen Dam serves as a case study for balancing flood control needs with proper maintenance and risk management protocols.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
