King Lake Dam dam
King Lake Dam
King Lake Dam, also known as Grindstone Lst-Mdy-Creek Site C-3 Dam, is a local government-owned structure located in DeKalb, Missouri. Built in 1971 by the USDA NRCS, this earth-type dam stands at 40 feet high and spans 1920 feet in length, serving primarily for flood risk reduction along the Lost Creek. With a normal storage capacity of 1293 acre-feet and a maximum storage of 4773 acre-feet, the dam covers a surface area of 184 acres and has a drainage area of 12200 acres.
The dam's spillway, designed as uncontrolled with a width of 200 feet, has a maximum discharge capacity of 13514 cubic feet per second. Despite its high hazard potential, King Lake Dam has been assessed as satisfactory in condition, with the last inspection conducted in January 2018. The dam's emergency action plan status and risk management measures are currently not updated, presenting a potential area for improvement in ensuring the safety and resilience of the structure in the face of climate change impacts.
King Lake Dam stands as a crucial infrastructure for flood risk reduction and recreational purposes in the region, regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri. With its strategic location and design, the dam plays a vital role in safeguarding the surrounding areas from potential flooding events. As water resource and climate enthusiasts, understanding the key details and features of King Lake Dam provides valuable insights into the management and maintenance of essential water infrastructure in the face of evolving environmental challenges.

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 King Lake Dam
Where does the data for King 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.
