Summary
The dam has a storage capacity of 560 acre-feet and serves a drainage area of 95 square miles.
Despite being categorized as having a low hazard potential, Strickland is considered to be in fair condition as of the last assessment in August 2014. With a moderate risk assessment rating of 3, there are no detailed risk management measures in place as of the latest data update in April 2021. The dam features an uncontrolled spillway with a width of 8 feet and has a maximum discharge capacity of 395 cubic feet per second. Overall, Strickland is a noteworthy structure for water resource and climate enthusiasts to monitor due to its historical significance and ongoing regulatory oversight.
In terms of regulatory oversight, Strickland is subject to state jurisdiction, regulation, permitting, inspection, and enforcement by the Idaho Department of Water Resources (IDWR). The dam is located within the Sacramento District of the US Army Corps of Engineers, and its operations and funding are solely managed by private entities. With a designated congressman representing the area, Russ Fulcher (R), Strickland remains an integral part of the local water resource infrastructure in Owyhee County, Idaho.

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.
