Walnut Glenn Lake Dam dam
Walnut Glenn Lake Dam
Walnut Glenn Lake Dam, located in Phelps County, Missouri, is a privately owned earth dam that stands at a height of 37 feet. The dam, designed by MCCAUL, serves the purpose of impounding water from an unnamed tributary of Camp Creek. With a storage capacity of 308 acre-feet and a maximum discharge of 383 cubic feet per second, the dam plays a crucial role in managing water resources in the area.
Despite being classified as having a significant hazard potential, Walnut Glenn Lake Dam has been deemed to be in satisfactory condition during its last assessment in 2012. The dam features an uncontrolled spillway and outlet gates, with a surface area of 13 acres and a drainage area of 325 square miles. The risk assessment for the dam is moderate, indicating a level 3 risk level, and it falls under the jurisdiction of the DAM AND RESERVOIR SAFETY PROG in Missouri.
With its strategic location and vital role in water management, Walnut Glenn Lake Dam represents a key infrastructure for the region. Water resource and climate enthusiasts will appreciate the dam's design and features, which contribute to the overall sustainability and resilience of the area's water supply system. The dam's inspection and regulatory processes ensure its continued operation and safety for the surrounding community and ecosystem.

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 Walnut Glenn Lake Dam
Where does the data for Walnut Glenn 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 Significant 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.
