Sprowls Dam dam
Sprowls Dam
Sprowls Dam, located in Humansville, Missouri, stands as a testament to the importance of water resource management and conservation efforts. Constructed in 1973, this earth dam serves primarily as a Fish and Wildlife Pond, providing a vital habitat for local flora and fauna. With a maximum storage capacity of 76 acre-feet and a normal storage of 20 acre-feet, the dam plays a crucial role in supporting the ecosystem in the area.
Despite its significant hazard potential and moderate risk assessment, Sprowls Dam has not been rated for its current condition. It stands at a height of 24 feet, with a structural height of 25 feet and a hydraulic height of 23 feet. The dam stretches for 605 feet and features an uncontrolled spillway with a width of 43 feet. While the dam itself is not regulated by the state, its presence is essential for maintaining the water levels in Brush Creek and providing recreational opportunities for the local community.
As water resource and climate enthusiasts, the intricate details of Sprowls Dam offer a fascinating glimpse into the intersection of human intervention and natural ecosystems. While the dam serves a specific purpose in terms of wildlife conservation, it also highlights the delicate balance required to manage water resources effectively. With its serene surface area of 5 acres and a drainage area of 90 acres, Sprowls Dam symbolizes the ongoing efforts to harness the power of nature for the benefit of both wildlife and the local community.

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 Sprowls Dam
Where does the data for Sprowls 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 Significant 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.
