Dwight Hammond dam
Dwight Hammond
Dwight Hammond is a privately owned Earth dam located in Mt. Shasta, California, along the Tr Shasta River. Built in 1959, this dam serves primarily for water supply purposes, including irrigation and water supply. With a height of 25 feet and a length of 720 feet, Dwight Hammond has a storage capacity of 348 acre-feet and covers a surface area of 58 acres, draining an area of 0.94 square miles.
Managed by the Department of Water Resources (DWR) and the Safety of Dams agency, Dwight Hammond is inspected regularly to ensure its safe operation. The dam has a low hazard potential and is currently in satisfactory condition, as assessed in September 2017. Despite having no associated structures, the dam plays a crucial role in providing water to the local community and supporting agricultural activities in the region. With its location in a picturesque setting in Siskiyou County, Dwight Hammond stands as a testament to the importance of water resource management in California.
As a key infrastructure for water supply in the area, Dwight Hammond's role in ensuring a reliable water source for the community cannot be understated. With its modest height and volume, this Earth dam continues to support the needs of residents and farmers in the region. The fact that it has been in operation for over six decades is a testament to its durability and the importance of proper maintenance and regulatory oversight in safeguarding water resources for the future.
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 Dwight Hammond
Where does the data for Dwight Hammond 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.
