Summary
Built in 1958, this earth dam stands at a height of 25.9 feet and has a hydraulic height of 22.8 feet, with a storage capacity of 550 acre-feet and a maximum discharge of 240 cubic feet per second. The dam serves primarily for purposes other than flood control or water supply, with a spillway designed for controlled release and a slide gate for outlet control.
Despite being assessed as in fair condition during the last inspection in April 2018, Dog Creek Dam is classified as having a significant hazard potential and a very high risk level. The dam has a drainage area of 5.5 square miles and covers a surface area of 53 acres. As part of the emergency action plan, the dam has a designated inspection frequency of 4 years and is equipped with a sluice gate for efficient water release. With its location in the Big Wood River area and surrounded by natural rock and soil foundations, Dog Creek Dam remains a crucial structure for water resource management in the region, attracting climate enthusiasts and water conservation advocates alike.

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.
