Lois Powers Pond dam
Lois Powers Pond
Located in Harmon, Oklahoma, Lois Powers Pond is a privately owned reservoir designed by USDA NRCS for multiple purposes, including water resource management and climate resilience. This earth dam structure, completed in 2002, stands at a height of 25.7 feet with a storage capacity of 69.9 acre-feet. The reservoir spans 3.5 acres and serves as a critical water source for the surrounding area, regulated by the Oklahoma Water Resources Board.
Managed by the Natural Resources Conservation Service, Lois Powers Pond is a vital component of the Washita River watershed, with a controlled spillway and a low hazard potential. Despite being labeled as "Not Rated" for its condition assessment, the reservoir plays a crucial role in flood control and irrigation for the region. With a drainage area of 523 square miles and a maximum discharge of 304 cubic feet per second, the pond is a key infrastructure ensuring water availability and ecosystem sustainability in the area.
With its very high risk assessment ranking, Lois Powers Pond demands careful monitoring and oversight to maintain its structural integrity and functionality. While currently not rated for condition assessment, the reservoir's low hazard potential emphasizes the importance of proactive risk management and emergency preparedness. As a significant water resource in the region, this earth dam structure underscores the intersection of water management, climate adaptation, and sustainable development in ensuring the resilience of local communities and ecosystems.

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 Lois Powers Pond
Where does the data for Lois Powers Pond 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 Low 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.
