Dyer Lake Dam dam
Dyer Lake Dam
Dyer Lake Dam, located in San Saba, Texas, is a private Earth dam completed in 1979 with a primary purpose of providing fire protection, stock, or a small fish pond. Standing at a height of 19 feet and a length of 835 feet, this dam has a storage capacity of 152 acre-feet, with a normal storage level of 76 acre-feet. It is situated on TR-HORSE CREEK and is under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
Despite being a privately owned structure, Dyer Lake Dam is subject to state permitting and inspection requirements. While it does not have a spillway, the dam is equipped with one outlet gate. The risk assessment for this dam indicates a high risk level (2), although specific risk management measures are not listed in the available data. The condition assessment is noted as "Not Rated," suggesting the need for further evaluation to determine the structural integrity and safety of the dam.
For water resource and climate enthusiasts, Dyer Lake Dam presents an interesting case study in the management of small-scale water infrastructure in Texas. With its unique design features and primary purposes, the dam serves as a vital resource for fire protection and agricultural needs in the local area. The risk assessment highlights the importance of ongoing monitoring and maintenance to ensure the safety and functionality of the dam for both human and ecological purposes.

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 Dyer Lake Dam
Where does the data for Dyer 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.
