Hickory Hollow Lake Dam Dam
Hickory Hollow Lake Dam
Hickory Hollow Lake Dam, located in Perry, Missouri, stands as a vital structure for both water resource management and climate enthusiasts. Completed in 1964, this Earth-type dam serves primarily for recreational purposes and boasts a height of 44 feet, a length of 760 feet, and a storage capacity of 830 acre-feet. The dam overlooks the TR-GOOSE CREEK and has a drainage area of 550 square miles, making it a key component in the region's water management system.
Managed by a private owner, the Hickory Hollow Lake Dam is regulated by the DAM AND RESERVOIR SAFETY PROG of Missouri, ensuring its compliance with state regulations and safety standards. Despite its high hazard potential, the dam's condition assessment in 2007 deemed it to be satisfactory, with routine inspections occurring every 3 years. In the event of an emergency, the dam has established emergency action plans to mitigate risks and protect the surrounding community.
With a moderate risk assessment level of 3, the Hickory Hollow Lake Dam remains a crucial structure for water management in the region. Its role in recreation, water storage, and hazard mitigation highlights the importance of maintaining and updating its infrastructure to ensure the safety and well-being of the surrounding areas. For water resource and climate enthusiasts, Hickory Hollow Lake Dam serves as a fascinating case study in dam management and the intersection of human development with natural resources.

About Hickory Hollow Lake Dam
Where does the data for Hickory Hollow 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 below 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.

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.
