Ross No. 2 dam
Ross No. 2
Ross No. 2 is a privately owned earth dam located in Redding, California, along the Tr Stillwater Creek. Completed in 1957, this dam stands at a height of 29 feet and has a storage capacity of 243 acre-feet. Its primary purpose is flood risk reduction, although it also serves irrigation and water supply needs in the area. The dam has a significant hazard potential but has been assessed as satisfactory in condition as of September 2017.
Managed by the California Department of Water Resources, Ross No. 2 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam has a drainage area of 0.23 square miles and a surface area of 22 acres. It is part of the flood risk reduction infrastructure in the region, contributing to the overall water resource management efforts in Shasta County. With its strategic location and design, Ross No. 2 plays a crucial role in protecting the surrounding communities from potential flood events.
In the event of an emergency, the dam's owners are expected to have an Emergency Action Plan in place, although specific details about its preparedness and compliance with guidelines are not provided in the available data. Overall, Ross No. 2 serves as a vital structure for water resource management and climate resilience in the area, highlighting the importance of maintaining and monitoring dams to mitigate risks and ensure the safety of downstream communities.

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 Ross No. 2
Where does the data for Ross 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.
