Hooper No. 2 dam
Hooper No. 2
Hooper No. 2 is a privately owned earth dam located in Hopland, California, along the Tr McDowell Creek. The dam stands at 20 feet in height and serves primarily for irrigation purposes, with a storage capacity of 120 acre-feet. Despite its fair condition assessment and significant hazard potential, the dam is regulated, permitted, inspected, and enforced by the California Department of Water Resources (DWR) under the Safety of Dams program. It falls under the jurisdiction of the state and has a designated state regulatory agency overseeing its operations.
Situated in Mendocino County, Hooper No. 2 is part of a water resource infrastructure maintained for agricultural irrigation in the region. The dam's maintenance and safety protocols are in place to ensure the protection of downstream communities and the environment in case of emergencies. With a designated emergency action plan (EAP) yet to be prepared and updated, the dam's risk assessment and management measures require attention to mitigate potential hazards. The last inspection in January 2020 highlighted the dam's need for continued monitoring and maintenance to uphold its integrity and safeguard the surrounding areas.
As climate change impacts water resources and infrastructure, the upkeep of dams like Hooper No. 2 becomes crucial for sustainable water management. With a focus on safeguarding irrigation capabilities and mitigating hazards, ongoing assessments and risk management strategies are essential for ensuring the dam's resilience in the face of changing environmental conditions. Collaboration between private owners, state agencies, and the local community is vital in sustaining water resources and climate resilience in the region.
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 Hooper No. 2
Where does the data for Hooper No. 2 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.
