Summary

Built in 2001, this dam serves primarily for irrigation purposes, with a storage capacity of 78 acre-feet and a surface area of 5.52 acres. The dam stands at a height of 25 feet, with a hydraulic height of 20 feet and a structural height of 32 feet, providing essential water resources for the surrounding area.

Managed by the Wyoming state regulatory agencies SEO and DEQ, T42nr75w14swse has a low hazard potential and fair condition assessment, making it a relatively safe structure. The dam features an uncontrolled spillway type with a width of 10 feet and an outlet gate valve for water release. With a moderate risk assessment score of 3, periodic inspections are carried out every 5 years to ensure the dam's integrity and safety. Overall, T42nr75w14swse plays a crucial role in supporting local irrigation needs and maintaining the balance of water resources in the region.

As part of the overall water management infrastructure in the area, T42nr75w14swse contributes to enhancing the local ecosystem by providing water for fish and wildlife ponds. With its strategic location and design by A. Bedard of Applied Hydrology, this dam represents a key asset for sustainable water resource management in Wyoming. Climate and water resource enthusiasts will find T42nr75w14swse an intriguing example of human-engineered structures harmonizing with natural landscapes to support both agricultural needs and ecological balance.

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.
