Lost Cr Pilot Watershed Dam E-1 dam
Lost Cr Pilot Watershed Dam E-1
Lost Cr Pilot Watershed Dam E-1, also known as Gentry Lake Dam, is a private earth dam in Lincoln, Missouri, built in 1959 for flood risk reduction along the TR-LOST CREEK. The dam stands at a height of 30 feet and has a structural height of 32 feet, with a length of 380 feet. It has a maximum storage capacity of 127 acre-feet and serves a drainage area of 25.6 square miles.
Although the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it has not been inspected since April 1980. Despite its age, Lost Cr Pilot Watershed Dam E-1 remains a vital structure for flood risk reduction in the area, with a moderate risk assessment score of 3. Located in the Kansas City District, this dam plays a crucial role in managing water resources and protecting the surrounding community from potential flooding events.
While Lost Cr Pilot Watershed Dam E-1 may not be under state regulation or jurisdiction, its significance in flood control cannot be understated. With a spillway width of 40 feet and a maximum discharge capacity of 1700 cubic feet per second, this dam serves as a key component in the local water management infrastructure. As climate change continues to impact the frequency and intensity of extreme weather events, the proper maintenance and monitoring of structures like Lost Cr Pilot Watershed Dam E-1 will be essential in ensuring the resilience of our water resources in the face of a changing climate.

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 Cr Pilot Watershed Dam E-1
Where does the data for Lost Cr Pilot Watershed Dam E-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.
