Roundhill Effluent Dam dam
Roundhill Effluent Dam
Located in Roundhill, Nevada, the Roundhill Effluent Dam is a vital structure owned by the local government and regulated by the Nevada Department of Water Resources. This earth dam, with a maximum height of 90 feet and a storage capacity of 160 acre-feet, serves as a key component in managing effluent from the surrounding area. The dam's primary purpose is listed as "Other," indicating its importance in water resource management and environmental protection efforts.
With a spillway width of 20 feet and three outlet gates, the Roundhill Effluent Dam has a high hazard potential but is currently assessed to be in fair condition. Regular inspections and enforcement by the state regulatory agency ensure the safety and functionality of the dam, which sits on the banks of Lake Tahoe-TR. The dam's risk assessment is moderate, highlighting the need for ongoing risk management measures to mitigate potential hazards and ensure the continued resilience of this critical water resource infrastructure.
As a key structure in the water management system of Douglas County, the Roundhill Effluent Dam plays a crucial role in protecting water quality and ensuring the sustainable use of resources in the region. Its location near Lake Tahoe-TR and its high hazard potential underscore the importance of proactive maintenance and risk management to safeguard both the environment and the community. For water resource and climate enthusiasts, the Roundhill Effluent Dam represents a focal point for understanding the intersection of infrastructure, regulation, and environmental stewardship in managing water resources in Nevada.
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 Roundhill Effluent Dam
Where does the data for Roundhill Effluent 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.
