Richward W Cook Jr. dam
Richward W Cook Jr.
Richward W Cook Jr. is a private dam located in Sandy Hook, Missouri, along TR Little Moniteau Creek. Completed in 1961, this recreational dam stands at a height of 20 feet and has a storage capacity of 64 acre-feet. With a primary purpose of recreation and water supply, this earth dam with a buttress core type covers a surface area of 6 acres and serves a drainage area of 115 square miles.
Situated in Moniteau County, Missouri, Richward W Cook Jr. is owned by a private entity and is not regulated or inspected by the state. Despite its low hazard potential and not being rated for its condition assessment, this dam provides essential recreational opportunities and water supply benefits to the surrounding community. With a maximum storage capacity of 64 acre-feet and a normal storage level of 30 acre-feet, Richward W Cook Jr. serves as a vital resource for water enthusiasts and climate advocates in the region.
Managed by the St. Louis District of the US Army Corps of Engineers, Richward W Cook Jr. offers a tranquil oasis for outdoor activities while also supporting water supply needs. Although not currently assessed for its condition or equipped with emergency action plans, this dam continues to play a significant role in the local ecosystem. For water resource and climate enthusiasts, Richward W Cook Jr. stands as a testament to the importance of sustainable water management and recreational infrastructure in the face of changing environmental conditions.

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 Richward W Cook Jr.
Where does the data for Richward W Cook Jr. 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.
