Crane Gulch East Dam dam
Crane Gulch East Dam
Crane Gulch East Dam, located in Boise, Idaho, is a local government-owned structure designed by Morrison Knudsen Corp and regulated by the Idaho Department of Water Resources. Completed in 1998, this earth dam stands at a height of 60.4 feet and serves the primary purpose of flood risk reduction along the unnamed stream Crane Creek. With a storage capacity of 28 acre-feet and a maximum discharge of 1900 cubic feet per second, the dam plays a crucial role in managing water resources in the area.
The dam's spillway, with a width of 150 feet, is uncontrolled, and it has been assessed to have a significant hazard potential but with a satisfactory condition as of the last inspection in November 2018. The dam's risk assessment is moderate, with a DSAC (Dam Safety Action Classification) assigned date yet to be determined. While the structure does not have outlet gates, its drainage area of 2.3 square miles and surface area of 2 acres contribute to its effective flood risk reduction capabilities. As water resource and climate enthusiasts, understanding the design, function, and regulatory oversight of Crane Gulch East Dam offers valuable insights into its role in water management within the Ada County region.
Overall, Crane Gulch East Dam stands as a vital infrastructure component in the region's water resource management efforts, showcasing the collaboration between local government, design firms, and regulatory agencies. As enthusiasts interested in the intersection of water resources and climate, the dam's specifications, maintenance history, and risk assessment provide valuable information on its contribution to flood risk reduction and environmental stewardship. Stay tuned for updates on the dam's operations, inspections, and any future modifications that may enhance its effectiveness in safeguarding the surrounding communities against potential water-related hazards.

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 Crane Gulch East Dam
Where does the data for Crane Gulch East Dam 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.
