Lake Ann Dam dam
Lake Ann Dam
Located in Montgomery, Texas, Lake Ann Dam stands as a testament to the intersection of water resource management and climate considerations. Completed in 1969, this private-owned dam serves primarily for recreational purposes, providing a serene oasis for visitors to enjoy. With a height of 16 feet and a storage capacity of 60 acre-feet, the dam plays a crucial role in regulating the flow of the TR-WEIRS CREEK, ensuring water availability for both human and environmental needs.
Operated under the oversight of the Texas Commission on Environmental Quality (TCEQ), Lake Ann Dam represents a vital link in the state's water infrastructure. Despite its age, the dam's structural integrity remains sound, with a high hazard potential rating emphasizing the need for regular inspections and monitoring. With no spillway and limited emergency preparedness measures in place, the risk of potential hazards underscores the importance of ongoing risk management and maintenance efforts to safeguard both the dam and surrounding communities.
As a key feature of the Fort Worth District, Lake Ann Dam stands as a symbol of the intricate balance between water resource utilization and climate resilience. With its earth core design and buttress foundation, the dam exemplifies the engineering ingenuity required to harness natural resources while mitigating potential risks. As water resource and climate enthusiasts, the preservation and sustainable management of Lake Ann Dam serve as a reminder of the critical role that infrastructure plays in supporting both human needs and environmental well-being in an ever-changing climate landscape.

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 Lake Ann Dam
Where does the data for Lake Ann 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.
