Summary

This dam, with a height of 34.3 feet and a length of 850 feet, serves the primary purpose of debris control on Elk Creek. It has a normal storage capacity of 68 acre-feet and a maximum discharge rate of 1522 cubic feet per second, making it a crucial structure for managing water resources in the area.

Although categorized as having a low hazard potential and a moderate risk assessment, Gs Dd No C-42 (Elk 23) is not currently rated for its condition. The dam does not have outlet gates and features an uncontrolled spillway with a width of 40 feet. While it has not been inspected recently and lacks an Emergency Action Plan (EAP), the dam remains under state regulation and jurisdiction, with permitting, inspection, and enforcement processes in place. Overall, this dam plays a vital role in debris control and water management in the region, highlighting the importance of monitoring and maintaining such critical infrastructure for climate and water resource enthusiasts.

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. 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

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, 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.
