Summary
1 is a privately owned earth dam located in Goshen, Wyoming, along the Garrelts Draw river. Built in 1975 by designer J. H. Coffman, this dam serves primarily for irrigation purposes and stands at a height of 17 feet with a length of 1200 feet. With a storage capacity of 205 acre-feet and a surface area of 42 acres, this dam plays a crucial role in water resource management in the region.
Despite its importance, Garrelts No. 1 is currently classified as having a low hazard potential and poor condition assessment, as of the last inspection in May 2017. The dam features an uncontrolled spillway type with a width of 55 feet and a single slide gate outlet. It is subject to state regulation, permitting, inspection, and enforcement, highlighting the commitment to ensuring its safety and functionality. While it has a moderate risk assessment rating, there are no specific risk management measures or emergency action plans documented for this structure.
Overall, Garrelts No. 1 represents a significant piece of infrastructure within the water management system of Wyoming. Its presence along the Garrelts Draw river contributes to the irrigation needs of the area, despite its current condition assessment and risk level. As water resource and climate enthusiasts, understanding the status and management of dams like Garrelts No. 1 is crucial for ensuring the sustainability and safety of our water supply systems in the face of changing environmental conditions.

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.
