Lake Lynn Dam dam
Lake Lynn Dam
Located in Wayne County, Missouri, Lake Lynn Dam, also known as Donnie Ort Lake Dam #1, is a privately owned earth dam that was completed in 1991 for recreational purposes. The dam stands at a height of 59 feet and has a length of 500 feet, creating a reservoir with a storage capacity of 662 acre-feet. The dam is situated on TR Lick Creek and is regulated by the DAM AND RESERVOIR SAFETY PROG, with regular inspections and enforcement to ensure its structural integrity.
With a hazard potential rated as high and a satisfactory condition assessment as of 2008, Lake Lynn Dam poses moderate risks that are actively managed through regular inspections and a designated emergency action plan. The spillway type for the dam is uncontrolled, with a width of 10 feet, and it has a maximum discharge of 561 cubic feet per second. Despite its potential risks, the dam provides valuable recreational opportunities and serves as a vital water resource in the region, with a surface area of 25 acres and a drainage area of 160 acres.
Lake Lynn Dam is a significant landmark in the McGee area, offering residents and visitors alike a scenic and recreational oasis. With its strategic location on TR Lick Creek and its vital role in water management, the dam stands as a testament to the importance of preserving and maintaining our water resources in the face of changing climate conditions. As enthusiasts of water resources and climate, exploring the history and engineering behind Lake Lynn Dam can provide valuable insights into the intersection of human infrastructure and natural environments.
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 Lake Lynn Dam
Where does the data for Lake Lynn 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.
