Allan Meinen Dam dam
Allan Meinen Dam
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. 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.
- 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.
- 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.
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, environmental 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.

About Allan Meinen Dam
Where does the data for Allan Meinen Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Not Available hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
