Grebe Lake Dam dam
Grebe Lake Dam
Grebe Lake Dam, located in Gasconade, Missouri, is a private-owned structure primarily used for recreation purposes. Built in 1970, this earth dam stands at a height of 30 feet and has a storage capacity of 48 acre-feet. Situated on TR-Horstman Creek, this dam covers a surface area of 3 acres and serves a drainage area of 21 square miles. Despite its low hazard potential, the condition of Grebe Lake Dam is currently not rated, and it has not undergone recent inspections or assessments.
The dam, with its buttress core type and unknown foundation, offers a tranquil setting for water resource and climate enthusiasts to explore. Surrounded by the natural beauty of Gasconade County, Missouri, this dam provides opportunities for outdoor activities such as fishing, boating, and hiking. While the dam's emergency action plan and risk management measures are not currently specified, its location within the St. Louis District offers a unique experience for visitors to appreciate the importance of water resources in the region.
For those interested in the intersection of water resource management and recreational opportunities, Grebe Lake Dam presents a fascinating case study. With its quaint setting in New Haven, Missouri, and the oversight of private ownership, this dam serves as a reminder of the delicate balance between human recreation and environmental conservation. As enthusiasts explore the area around Grebe Lake Dam, they can reflect on the importance of responsible stewardship of our water resources for future generations to enjoy.

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 Grebe Lake Dam
Where does the data for Grebe 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.
