Vineyard Subdivision dam
Vineyard Subdivision
Vineyard Subdivision, also known as Vineyard Lake, is a private water supply dam located in Geyserville, California. Built in 1962, this earth dam stands at 26 feet high and has a storage capacity of 245 acre-feet. The dam's primary purpose is to provide water for the surrounding area, with secondary purposes including recreation. It is regulated and permitted by the California Department of Water Resources and is subject to regular inspections to ensure its safety and proper functioning.
Situated on Tr Gill Creek in Sonoma County, Vineyard Subdivision plays a crucial role in water management and supply in the region. The dam has a significant hazard potential but has been assessed as satisfactory in condition as of September 2017. The inspection frequency is set at once per year, with the last inspection conducted in January 2020. Despite its age, the dam continues to serve its intended purposes effectively, highlighting the importance of proper maintenance and regulation in ensuring the safety and reliability of water resources in the area.
With its strategic location and vital role in water supply, Vineyard Subdivision serves as a key asset for the community of Geyserville and surrounding areas. Its satisfactory condition and adherence to regulatory standards demonstrate a commitment to water resource management and the safety of dams. As water resource and climate enthusiasts, understanding the infrastructure and maintenance of dams like Vineyard Subdivision is essential for ensuring the sustainable and efficient utilization of water for both human consumption and recreational activities in the region.

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 Vineyard Subdivision
Where does the data for Vineyard Subdivision 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 Significant 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.
