Summary
The dike, primarily made of earth and stone, stands at a height of 24.6 feet and has a storage capacity of 35,300 acre-feet. It spans 1,800 feet in length and is designed to regulate water flow from Crane Creek and the Weiser River, covering a drainage area of 242 square miles.
Maintained by a private owner, the Crane Creek Dike is regulated by the Idaho Department of Water Resources, with regular inspections to ensure its structural integrity. With a high hazard potential and fair condition assessment, the dike plays a vital role in flood control and water conservation efforts in the region. It features slide gates for water release and does not have a spillway, highlighting its traditional yet effective design for managing water levels.
Despite its age, the Crane Creek Dike continues to be a key infrastructure for safeguarding the surrounding communities from potential flooding events. With a high risk assessment level, the dike underscores the importance of proactive risk management measures and emergency preparedness to mitigate any potential hazards and ensure the longevity of this critical water resource structure.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
