Lost Lake Dam dam
Lost Lake Dam
Lost Lake Dam, located in Comanche, Oklahoma, along the WEST CACHE CREEK, was completed in 1926 by the City of Lawton and is currently owned and operated by the Fish and Wildlife Service. This masonry dam stands at a height of 23 feet with a hydraulic height of 23 feet and a structural height of 25 feet, providing a normal storage capacity of 95 acre-feet for its primary purpose as a Fish and Wildlife Pond. With a low hazard potential and a poor condition assessment as of the last inspection in 2015, Lost Lake Dam is in need of maintenance and improvements to ensure its long-term safety and functionality.
The dam has a spillway width of 97 feet and an uncontrolled spillway type, with a maximum discharge capacity of 475 cubic feet per second. Despite its moderate risk rating, Lost Lake Dam has not undergone modifications in recent years and lacks an Emergency Action Plan (EAP) preparedness. The inspection frequency is set at 5 years, and the dam is monitored by the Fish and Wildlife Service, which also handles its design, construction, regulatory, inspection, and operational functions. The surrounding area boasts a surface area of 11.1 acres and a drainage area of 16.8 square miles, providing valuable habitat for local wildlife and recreational opportunities for visitors.
Lost Lake Dam serves as a vital resource for water management and conservation efforts in the region, supporting the ecological balance of the area and providing a habitat for various species. With its historical significance dating back to the early 20th century, the dam requires attention to ensure its continued functionality and safety for both wildlife and the community. As water resource and climate enthusiasts, understanding the importance of maintaining and improving dams like Lost Lake Dam is crucial for sustainable water management practices and environmental preservation in the face of changing climate conditions.

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 Lost Lake Dam
Where does the data for Lost 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 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.
