Clarence City New Lake Dam dam
Clarence City New Lake Dam
Clarence City New Lake Dam, located in Clarence, Missouri, was completed in 1956 and serves as a local government-owned structure primarily designed for recreation and water supply purposes. With a height of 30 feet and a storage capacity of 321 acre-feet, the dam sits on the TR TO BATTON BRANCH stream within the St. Louis District of Missouri. Although not regulated by the state, the dam is considered to have a high hazard potential, though its condition assessment is currently not rated.
Despite lacking certain inspection and emergency preparedness measures, Clarence City New Lake Dam remains a significant water resource in the Shelby County area, providing both recreational opportunities and essential water supply functions. The dam's Earth-type construction, with a buttress core and unknown foundation, supports a surface area of 20 acres and a drainage area of 289 square miles. While there are no associated structures or outlet gates, the dam's storage capacity and location make it a vital asset for the local community.
Water resource and climate enthusiasts interested in the Clarence City New Lake Dam can appreciate its historical significance, construction details, and the potential risks associated with its operation. With a focus on recreation and water supply, this dam continues to play a crucial role in the region's water management efforts, despite lacking certain regulatory oversight and assessment ratings. As part of the broader network of dams within the St. Louis District, Clarence City New Lake Dam showcases the intersection of infrastructure, natural resources, and community needs in safeguarding water resources for future generations.

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 Clarence City New Lake Dam
Where does the data for Clarence City New Lake 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 High 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.
