Lost Lake Wpa 1 dam
Lost Lake Wpa 1
Lost Lake WPA 1, located in McLean, North Dakota, is a Federal-owned fish and wildlife pond designed by USFWS. Completed in 1990, this Earth-type dam stands at a height of 7 feet and has a storage capacity of 50 acre-feet on its 64-acre surface area. The dam is primarily used for wildlife conservation purposes and is situated along the Painted Woods Creek-TR, under the jurisdiction of the state of North Dakota.
Despite its low hazard potential and moderate risk assessment, Lost Lake WPA 1 has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 20 feet and a vertical lift outlet gate. While it has not been inspected recently and lacks an emergency action plan, the structure is maintained by the St. Paul District of the US Army Corps of Engineers. With its scenic location and importance for local wildlife, Lost Lake WPA 1 serves as a vital water resource in the region.
For water resource and climate enthusiasts, Lost Lake WPA 1 offers a glimpse into the intersection of environmental conservation and infrastructure development. As a key component of the local ecosystem, this dam plays a crucial role in providing habitat for various wildlife species while managing water flow along Painted Woods Creek-TR. With its moderate risk assessment and lack of recent inspections, there is a need for continued monitoring and maintenance to ensure the long-term viability of this important water resource in North Dakota.

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 Wpa 1
Where does the data for Lost Lake Wpa 1 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.
