Humphrey's Lake Dam dam
Humphrey's Lake Dam
Humphrey's Lake Dam in Haseville, Missouri, is a private earth dam completed in 1960 for the primary purpose of recreation. The dam, situated on TR-East Fork Medicine Creek, stands at a height of 32 feet and has a storage capacity of 154 acre-feet. The reservoir created by the dam covers an area of 9 acres and serves as a water supply for various recreational activities.
Despite being unregulated by the state, Humphrey's Lake Dam has a low hazard potential and is currently in a not rated condition assessment. The dam's structural integrity and safety are maintained through regular inspections, although no specific inspection frequency is listed. The dam's emergency action plan (EAP) status, risk assessment, and management measures are not provided in the data, suggesting a need for further evaluation and documentation in case of emergencies.
Located within the Rock Island District, Humphrey's Lake Dam offers a tranquil setting for outdoor enthusiasts to enjoy water-based activities such as fishing, boating, and swimming. With its picturesque surroundings and recreational opportunities, the dam serves as a valuable resource for the local community while also contributing to the region's water supply needs. As climate change continues to impact water resources, maintaining the safety and functionality of dams like Humphrey's Lake Dam becomes increasingly important for sustainable water management in the future.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Humphrey's Lake Dam
Where does the data for Humphrey's 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.
