Asti dam
Asti
Asti is a privately owned dam located in Sonoma County, California, near the city of Healdsburg. Built in 1955, this Earth-type dam serves primarily for water supply purposes, specifically irrigation and water supply. With a height of 34 feet and a length of 900 feet, Asti has a storage capacity of 325 acre-feet and covers a surface area of 14 acres. It is regulated by the California Department of Water Resources (DWR) under the Safety of Dams program, ensuring regular inspections and enforcement to maintain its satisfactory condition.
Situated on the Tr Russian River, Asti plays a crucial role in managing water resources in the region, serving as a vital source of water for agricultural and domestic use. Despite its low hazard potential and satisfactory condition assessment as of September 2017, the dam undergoes frequent inspections every year to ensure its continued safety and functionality. The San Francisco District of the US Army Corps of Engineers is not involved in the ownership, funding, design, construction, or operation of Asti.
Asti's location and design by the Natural Resources Conservation Service reflect its importance in the water infrastructure of Sonoma County. With its regulated status, the dam contributes to the sustainable management of water resources in the area, highlighting the importance of maintaining and monitoring critical infrastructure in the face of changing climate conditions. As a key component of the water supply system, Asti underscores the intersection of water resource management and climate resilience in California's diverse and dynamic landscape.

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 Asti
Where does the data for Asti 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.
