Willow Creek Watershed Dam A- 22 dam
Willow Creek Watershed Dam A- 22
Located in the heart of Missouri, the Willow Creek Watershed Dam A- 22 is a vital structure designed by USDA NRCS to serve the primary purpose of grade stabilization. Built in 1970, this earth dam stands at a height of 33 feet and has a structural height of 35 feet, with a length of 885 feet. With a storage capacity of 312 acre-feet and a drainage area of 650 acres, this dam plays a crucial role in managing water resources in the region.
With a low hazard potential and a moderate risk assessment rating, the Willow Creek Watershed Dam A- 22 ensures the safety of the surrounding communities in Henrietta, Missouri. The dam features an uncontrolled spillway with a width of 60 feet, providing effective flood control measures for the area. Despite being not rated for its condition assessment, the dam continues to serve its intended purpose of grade stabilization, contributing to the overall water resource management efforts in the region.
As part of the Rock Island District, this dam is a testament to the collaboration between local government and federal agencies in ensuring the resilience of water infrastructure in the face of changing climate patterns. With a focus on sustainability and risk management, the Willow Creek Watershed Dam A- 22 stands as a symbol of effective water resource management and climate adaptation strategies in Missouri's Ray County.

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 Willow Creek Watershed Dam A- 22
Where does the data for Willow Creek Watershed Dam A- 22 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.
