Dam Lake Norconian West dam
Dam Lake Norconian West
Dam Lake Norconian West, also known as West Norconian Lake Dam, is a fascinating water resource nestled in Riverside, California. Owned and operated by the US Navy, this Federal dam was completed in 1928 with a primary purpose of recreation. Standing at a height of 20 feet and stretching 525 feet in length, it holds a maximum storage capacity of 453 acre-feet and covers a surface area of 45 acres.
With a high hazard potential but fair condition assessment, Dam Lake Norconian West is a crucial structure for water management in the region. The dam regulates the flow of the West Norco Channel, with an uncontrolled spillway type and valve outlet gates. Despite its age, the dam remains in operation under the careful monitoring of the US Navy, ensuring its safety and functionality for the surrounding community.
For water and climate enthusiasts, Dam Lake Norconian West offers a unique opportunity to explore the intersection of infrastructure and natural resources. With a moderate risk assessment and regular inspections, this historic dam continues to play a vital role in water storage and recreation in the Riverside area. Its rich history and engineering design make it a noteworthy site for those interested in the management and conservation of water resources.

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 Dam Lake Norconian West
Where does the data for Dam Lake Norconian West 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.
