Hiser Dam No 1 dam
Hiser Dam No 1
Hiser Dam No 1, located in Millville, Missouri, was completed in 1992 and serves as a crucial resource for fish and wildlife pond management. The earth dam stands at a height of 33 feet and has a storage capacity of 110 acre-feet, with a normal storage level of 71 acre-feet. With a surface area of 4 acres and a drainage area of 32 square miles, the dam plays a significant role in grade stabilization and recreation in the area.
Managed by a private owner, Hiser Dam No 1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite being unregulated by the state, the dam's spillway type is uncontrolled with a width of 16 feet, allowing for a maximum discharge of 256 cubic feet per second. While the dam has not been inspected in recent years, its risk assessment is moderate, highlighting the importance of proper management and maintenance to ensure the safety and functionality of the structure.
As part of the Rock Island District's portfolio, Hiser Dam No 1 is a notable feature along the TR-East Fork Crooked River. With its primary purpose of supporting fish and wildlife habitats, the dam contributes to the ecological diversity of the region. While the dam does not have an Emergency Action Plan (EAP) in place, its risk management measures are under review, emphasizing the need for proactive measures to address potential hazards and ensure the long-term sustainability of the dam and surrounding areas.

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 Hiser Dam No 1
Where does the data for Hiser Dam No 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.
