Summary
This earth dam, constructed in 1978, stands at a height of 18.2 meters and has a storage capacity of 68 acre-feet. The dam spans 750 meters and is situated on an unnamed stream called Tennison Creek, in the Walla Walla District. Despite its low hazard potential and fair condition assessment, the dam is regulated by the Idaho Department of Water Resources, with inspection, enforcement, and permitting responsibilities falling under the state jurisdiction.
With a drainage area of 1.1 square kilometers and a maximum discharge capacity of 129 cubic meters per second, Craig serves as a vital water management infrastructure in the region. Its controlled by an uncontrolled spillway, 35 meters wide, providing necessary safety measures. The dam's inspection frequency is set at 5 years, with the last assessment conducted in June 2018. Although classified as having a moderate risk level, with a risk factor of 3, Craig continues to play a crucial role in supporting irrigation activities in the area. As a climate and water resource enthusiast, monitoring the condition and management of structures like Craig is essential for ensuring sustainable water use in the face of changing environmental conditions.

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.
