Coos Ctry Club 15th Hole Dam dam
Coos Ctry Club 15th Hole Dam
Located in Coos County, Oregon, the Coos Country Club 15th Hole Dam, also known as Menasha Reservoir, is a private dam with a primary purpose of recreation. This dam is regulated by the Oregon Water Resources Department and is subject to state permitting, inspection, and enforcement. With a height of 25 feet and a storage capacity of 27.4 acre-feet, this dam serves as both a recreational spot and a water supply source in the region.
The Coos Country Club 15th Hole Dam features a needle outlet gate and has been assessed to have a low hazard potential. Despite not having a condition rating, this dam is regularly inspected, with the last inspection conducted in September 2015. The dam does not fall under the jurisdiction of the US Army Corps of Engineers and has not undergone any significant modifications over the years. While the dam does not currently have an Emergency Action Plan prepared or updated, it meets safety guidelines and is deemed to be in a stable condition.
Climate and water resource enthusiasts visiting the Coos Country Club 15th Hole Dam can appreciate its role in providing recreational opportunities while also contributing to water supply needs in the area. With its serene location and low hazard potential, this dam stands as a testament to responsible dam management and serves as a vital infrastructure for the community. As efforts continue to ensure its safety and regulatory compliance, this dam remains an important feature in the water management landscape of Coos County, Oregon.

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 Coos Ctry Club 15th Hole Dam
Where does the data for Coos Ctry Club 15th Hole 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.
