Snyder Dam dam
Snyder Dam
Snyder Dam, located in Adair, Missouri, is a privately owned earth dam constructed in 1991 for the primary purpose of grade stabilization along Walnut Creek. Standing at a height of 34 feet and stretching 240 feet in length, the dam has a storage capacity of 42 acre-feet and serves a drainage area of 160 acres. Despite its modest size, Snyder Dam plays a crucial role in managing water flow and preventing erosion in the surrounding area.
With a low hazard potential and a moderate risk assessment score of 3, Snyder Dam is considered to be in good condition and poses minimal risk to the downstream community. Although the dam has not been rated for its condition assessment, it is equipped with an uncontrolled spillway and lacks outlet gates. While no emergency action plan (EAP) has been prepared for this structure, it meets regulatory guidelines and has not required any major modifications since its completion. Overall, Snyder Dam serves as a vital resource for maintaining water quality and protecting the local environment in the region.
Managed by the Rock Island District of the US Army Corps of Engineers, Snyder Dam is an essential component of the infrastructure that supports the community of Elmer. As a key feature of the watershed, it helps regulate water levels, mitigate flood risks, and ensure the sustainability of the local ecosystem. Water resource and climate enthusiasts can appreciate Snyder Dam for its significant role in maintaining the balance of water resources and protecting the environment in Adair County, Missouri.

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 Snyder Dam
Where does the data for Snyder 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.
