Misselbeck dam
Misselbeck
Misselbeck, also known as Rainbow Lake, is a public utility dam located in Shasta, California. Built in 1920, this earth dam stands at 96 feet tall and stretches 470 feet in length, with a storage capacity of 3,600 acre-feet. The dam serves multiple purposes, including flood risk reduction, irrigation, and water supply for the surrounding area along Nfk Cottonwood Cr.
Despite its significant contribution to water resource management in the region, Misselbeck poses a high hazard potential due to its poor condition assessment. The dam has been flagged for regular inspections and enforcement by the California Department of Water Resources (DWR) and Safety of Dams agency. It is crucial for water resource and climate enthusiasts to monitor the maintenance and risk management measures for Misselbeck to ensure the safety of downstream communities in the event of an emergency.
Given its historical significance and vital role in water supply infrastructure, Misselbeck underscores the importance of proactive monitoring and maintenance of aging dams. As a key player in flood risk reduction and water supply management, the dam's condition assessment, emergency action plan preparation, and risk management measures must be regularly updated to mitigate potential hazards and safeguard the surrounding environment and communities. Continued oversight and investment in the upkeep of dams like Misselbeck are essential for sustainable water resource management in the face of changing climate conditions.

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 Misselbeck
Where does the data for Misselbeck 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.
