Mosher Little Lake Dam dam
Mosher Little Lake Dam
Mosher Little Lake Dam, located in Bandera, Texas, is a private earth dam constructed in 1942 for recreational purposes. Standing at a height of 17.3 feet and spanning a length of 874 feet, the dam holds a maximum storage capacity of 220 acre-feet and covers a surface area of 15 acres. The dam, designed by Mr. Slats Rogers, is situated on the TR-Bandera Creek and is regulated by the state with regular inspections conducted since its completion.
Despite its moderate risk assessment, with a hazard potential not available and a condition assessment not rated, the dam has not been assigned a Dam Safety Action Classification (DSAC) date. The spillway, categorized as uncontrolled, has a width of 162 feet and can handle a maximum discharge of 7770 cubic feet per second. With four uncontrolled outlet gates, the dam has not been updated or revised in recent years, with the last inspection recorded in July 2010.
Water resource and climate enthusiasts may find Mosher Little Lake Dam a fascinating structure to study due to its historical significance and design features. As a recreational dam on Bandera Creek, it provides a valuable resource for the community while also posing certain risks that may require further assessment and management measures in the future. The dam's engineering and construction details, along with its regulatory oversight and potential for environmental impact, make it a noteworthy subject for ongoing research and monitoring in the field of water resource management.

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 Mosher Little Lake Dam
Where does the data for Mosher Little Lake 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.
