About this dam

Harke Lake Dam

Harke Lake Dam, located in Phelps, Missouri, on the TR-BIG PINEY RIVER, was completed in 1972 for the primary purpose of recreation. Owned privately, the dam stands at a height of 25 feet and has a storage capacity of 80 acre-feet. With a surface area of 6 acres and serving a drainage area of 55 square miles, the dam offers a tranquil setting for water resource and climate enthusiasts to enjoy various recreational activities.

Despite being classified as low hazard potential and in a condition not yet rated, Harke Lake Dam has not been regulated or inspected by the state authorities. However, its location in the scenic city of EVENING SHADE, Missouri, adds to the allure of the site for visitors seeking to immerse themselves in nature's beauty. With a latitude of 37.61801679 and longitude of -91.97784046, the dam's peaceful surroundings make it a perfect destination for those looking to connect with the great outdoors.

Although not under federal jurisdiction, Harke Lake Dam continues to serve as a haven for outdoor enthusiasts, offering a serene escape from the hustle and bustle of everyday life. Its uninterrupted flow of the TR-BIG PINEY RIVER, coupled with its private ownership and focus on recreation, make it a must-visit destination for water resource and climate enthusiasts looking to unwind and appreciate the beauty of nature in the heart of Missouri.

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.

FAQ

About Harke Lake Dam

Where does the data for Harke 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.
