Summary
3 is a private irrigation dam located on Dogie Creek in Niobrara, Wyoming. Built in 1952, this Earth dam stands at a height of 21 feet and has a hydraulic height of 15 feet, serving the primary purpose of irrigation. With a storage capacity of 342 acre-feet and a surface area of 28 acres, this structure plays a crucial role in water resource management in the region.
Despite its importance, Dogie No. 3 is assessed to be in poor condition as of the last inspection in May 2017. The dam has a low hazard potential, but the risk assessment indicates a moderate level of risk. With an uncontrolled spillway and a single slide gate for outlet control, there are concerns about the structural integrity of the dam and the potential impact of a failure on the surrounding area.
As climate change continues to impact water resources and infrastructure, the maintenance and monitoring of dams like Dogie No. 3 become increasingly vital. With its location in a regulated state and state-permitted status, there is a framework in place for ongoing inspection, enforcement, and risk management. It is essential for water resource and climate enthusiasts to advocate for the upkeep of such critical infrastructure to ensure the safety and sustainability of our water systems.

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.
