Highway Lake Dam dam
Highway Lake Dam
Highway Lake Dam, located in Phelps County, Missouri, was completed in 1952 and serves primarily for recreation purposes. The dam stands at a height of 33 feet, with a storage capacity of 265 acre-feet and a normal storage of 175 acre-feet. Situated on Peters Branch, this earth dam with a buttress core type covers a surface area of 15 acres and drains an area of 870 acres.
Despite being privately owned and not regulated by the state, Highway Lake Dam has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. With no inspection frequency listed and limited emergency preparedness measures in place, the dam's risk assessment and management measures are not clearly outlined. While the dam does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, it still provides a vital recreational resource for the surrounding community.
As water resource and climate enthusiasts explore the data on Highway Lake Dam, its unique features and minimal risk factors make it a fascinating subject of study. With its scenic location and historical significance in the area, the dam continues to be a valuable asset for recreational activities while also highlighting the importance of proper maintenance and emergency preparedness in safeguarding water resources and infrastructure.
Dam data reference
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 Highway Lake Dam
Where does the data for Highway 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 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.
