About this dam

Stanford Heights

Located in the heart of San Francisco, Stanford Heights Reservoir stands as a testament to the city's commitment to sustainable water management. Built in 1928, this offstream Earth dam serves as a critical water supply for the local community, boasting a height of 31 feet and a storage capacity of 37 acre-feet. With a surface area of 2 acres and a drainage area of 0, Stanford Heights Reservoir is a key player in ensuring water security for the region.

Managed by the local government and regulated by the California Department of Water Resources, Stanford Heights Reservoir has been deemed to have a high hazard potential, although its condition assessment remains satisfactory. The dam's last inspection in February 2020 indicated a need for regular monitoring and maintenance to ensure its continued safety and operational efficiency. With Nancy Pelosi as the area's congressional representative, Stanford Heights serves as a vital component in the broader water infrastructure network that supports the city's water supply needs.

As climate change continues to impact water resources worldwide, Stanford Heights Reservoir plays a crucial role in ensuring the resilience of San Francisco's water supply. With its strategic location and historical significance, the dam serves as a beacon of environmental stewardship and proactive water management practices. As the city faces evolving challenges related to water scarcity and extreme weather events, Stanford Heights Reservoir stands ready to meet the demands of a changing climate and secure a sustainable water future for generations to come.

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.

FAQ

About Stanford Heights

Where does the data for Stanford Heights 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.

Premium feature
