About this dam

Lost Lake Dam

Lost Lake Dam, located in Turner, Missouri, is a privately owned structure built in 1971 for fire protection, stock, and small fish pond purposes. Sitting on the TR to James River, this earth-type dam stands at a height of 35 feet with a structural height of 40 feet and a length of 400 feet, providing a storage capacity of 58 acre-feet. Despite its relatively small surface area of 5 acres, Lost Lake Dam plays a crucial role in regulating water flow in the region, with a maximum discharge capacity of 290 cubic feet per second.

Maintained and regulated by the DAM AND RESERVOIR SAFETY PROG of the state, Lost Lake Dam has a high hazard potential due to its location and design. Although its condition has not been rated, regular inspections are conducted to ensure its safety and integrity. The dam's emergency action plan was last revised in 2012, highlighting the importance of preparedness in case of unforeseen events. The risk assessment for Lost Lake Dam indicates a moderate level of risk, emphasizing the need for continued monitoring and management measures to mitigate potential hazards.

Lost Lake Dam stands as a vital structure in the water resource management system of Webster County, Missouri. With its primary purpose of providing essential services and its strategic location along the river, this dam serves as a key component in ensuring water availability for fire protection and agricultural needs in the area. As climate change continues to impact water resources, the maintenance and monitoring of dams like Lost Lake Dam become increasingly important in safeguarding both human and environmental wellbeing in the region.

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 Lost Lake Dam

Where does the data for Lost 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.
