Mcdonough Lake Dam dam
Mcdonough Lake Dam
Mcdonough Lake Dam, located in Callahan County, Texas, is a privately owned earth dam built in 1960 for water supply purposes on Turkey Creek. Standing at a height of 12 feet with a length of 850 feet, the dam has a storage capacity of 77 acre-feet. Despite being unregulated by the state, the dam is regularly inspected and permitted for operation. With a risk assessment rating of "High (2)", the dam is classified as having a moderate level of risk.
The dam, with a hazard potential that is not available and a condition assessment that is not rated, serves as an important water resource for the region. With no spillway and a single outlet gate, the dam plays a crucial role in water supply management for the surrounding area. Although the dam has not been modified in recent years, it is essential to ensure that proper risk management measures are in place to address any potential safety concerns.
With its structural design and purpose primarily focused on water supply, Mcdonough Lake Dam stands as a vital infrastructure in the region. As water resource and climate enthusiasts, it is important to recognize the significance of maintaining and monitoring such dams to ensure the safety and sustainability of our water supply systems. The dam's location on Turkey Creek highlights its importance in managing and regulating water flow in the area, making it a key component in the local ecosystem.

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 Mcdonough Lake Dam
Where does the data for Mcdonough 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.
