Summary
Built in 1980 by designer Bruce R. Yates, the dam stands at a height of 29 feet and has a hydraulic height of 24 feet, with a length of 830 feet. It has a storage capacity of 22 acre-feet and serves multiple purposes including fire protection, stock, and small fish pond in addition to irrigation. The dam is situated on the Hoblit Draw river and is regulated by the State of Wyoming, with inspection, permitting, and enforcement measures in place.
Despite its low hazard potential, Stump's condition assessment is rated as poor and it was last inspected in August 2017. The dam has an uncontrolled spillway with a width of 20 feet and one slide (sluice gate) outlet gate. The risk assessment for Stump is moderate, indicating potential risks that need to be managed. While the dam has not been modified in recent years, its maintenance and emergency preparedness measures may need to be updated to meet current guidelines and ensure safety for the surrounding area.

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.
