Summary
Built in 1956, this earth dam stands at 30 feet tall and has a storage capacity of 282 acre-feet, with a normal storage level of 129 acre-feet. The dam spans 776 feet in length and has a spillway width of 130 feet, with an uncontrolled spillway type.
The dam, situated on the N Prong Pumpkin Creek, is regulated by the State of Wyoming and is subject to regular inspections, with its condition assessed as fair during the last inspection in April 2020. With a low hazard potential and a moderate risk assessment rating, the dam poses minimal risk to surrounding areas. In case of emergencies, a single valve serves as the outlet gate for water release from the dam.
Overall, Innes serves as a vital water resource for fire protection and stock purposes in the area, while also doubling as a fish pond. Its strategic location and structural attributes make it an essential component of water management and conservation efforts in Campbell, Wyoming, catering to the needs of both humans and wildlife alike.

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.
