Ice House Dike No. 1 dam
Ice House Dike No. 1
Ice House Dike No. 1, also known as Ice House Auxiliary, is a crucial public utility structure located in Coloma, California, along the South Fork Silver Creek. This earth dam stands at a height of 57 feet with a hydraulic height of 51 feet, serving primarily for hydroelectric purposes and recreation. With a storage capacity of 43,496 acre-feet and a maximum discharge of 22,500 cubic feet per second, this dam plays a vital role in water resource management in the region.
Managed by the Federal Energy Regulatory Commission, Ice House Dike No. 1 has a significant hazard potential and is under state regulation, inspection, and enforcement by the Department of Water Resources. Despite lacking detailed condition assessment data, it is clear that this dam is integral for flood control and water supply in El Dorado County. With a risk assessment rating of High (2), it is essential for climate and water enthusiasts to monitor the maintenance and emergency preparedness efforts surrounding this critical infrastructure.
As a key component of the water infrastructure system in California, Ice House Dike No. 1 not only provides hydroelectric power but also contributes to recreational activities and water storage in the area. With its unique design and location, this dam serves as a reminder of the delicate balance between harnessing water resources for human needs and safeguarding against potential risks and hazards posed by natural forces. It is imperative for stakeholders and climate enthusiasts to stay informed about the condition and management of this structure to ensure the sustainable utilization of water resources 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 Ice House Dike No. 1
Where does the data for Ice House Dike No. 1 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.
