Summary

Designed by H. Lowham, this dam on Krenzien Draw stands at 30 feet tall with a hydraulic height of 27 feet and a structural height of 32 feet. It has a storage capacity of 87 acre-feet, with a normal storage of 42 acre-feet and a surface area of 4.7 acres. The dam is equipped with a valve outlet gate and an uncontrolled spillway with a width of 25 feet.

With a low hazard potential and fair condition assessment, Double Wide has a moderate risk level, as indicated by a risk assessment rating of 3. Despite being privately owned, the dam is regulated and inspected by the state, with permitting, inspection, and enforcement all handled by the Wyoming State Engineer's Office (SEO) and Department of Environmental Quality (DEQ). The dam's last inspection was conducted in May 2019, with an inspection frequency of 5 years.

Double Wide serves multiple purposes including fire protection, stock watering, and small fish pond in addition to irrigation. It is a vital infrastructure contributing to the water resource management in the area, providing essential water supply for agricultural activities and serving as a reservoir for various needs. As an important part of the water infrastructure in Sheridan County, Double Wide represents a significant investment in the sustainability and management of water resources in the region.

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.
