Lerwick Lake Dam dam
Lerwick Lake Dam
Lerwick Lake Dam, located in Gasconade, Missouri, is a privately owned structure that serves primarily for recreational purposes. Completed in 1977, this Earth-type dam stands at a height of 25 feet and has a storage capacity of 67 acre-feet. The dam overlooks the scenic TR-Bourbeuse River and covers a surface area of 5 acres, providing a serene environment for water resource and climate enthusiasts to enjoy.
Despite being privately owned, Lerwick Lake Dam has a low hazard potential and has not been rated for its condition. With no state regulation or inspection, the dam remains a hidden gem in the heart of Missouri, offering a peaceful getaway for locals and visitors alike. The dam's location near BEM and its proximity to the Kansas City District add to its appeal, attracting those interested in exploring lesser-known water resource and climate conservation efforts.
As a structure that blends into the natural landscape, Lerwick Lake Dam stands as a testament to the harmonious coexistence of man-made infrastructure and environmental preservation. With its unlisted foundation and buttress core, the dam symbolizes the balance between human recreation and the protection of aquatic ecosystems. For water resource and climate enthusiasts seeking a tranquil retreat in Gasconade County, Lerwick Lake Dam offers a unique opportunity to appreciate the beauty and importance of sustainable water management practices.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lerwick Lake Dam
Where does the data for Lerwick 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.
