Summary
1 is a privately owned earth dam located in Niobrara, Wyoming, along Boggy Creek. Built in 1972, this dam serves primarily for irrigation purposes, with a storage capacity of 1,499 acre-feet and a normal storage of 997 acre-feet. The dam stands at a height of 43 feet and has a spillway width of 250 feet, designed for uncontrolled spillage during high water events. The structure has a low hazard potential and is assessed to be in fair condition as of the last inspection in July 2017.
Managed by the Wyoming State Engineer's Office, New Deal No. 1 is subject to state regulations, permitting, inspections, and enforcement activities to ensure its safe operation and compliance with standards. Despite being a privately owned facility, it plays a crucial role in supporting agricultural activities in the region by providing water for irrigation. Congresswoman Liz Cheney represents the area in the Congressional District 00, Wyoming, where the dam is located, highlighting the importance of water resource management and climate resilience in the region.
Overall, New Deal No. 1 showcases the intersection of water resource management, climate considerations, and infrastructure development in rural Wyoming. As a key component of the local irrigation system, the dam plays a vital role in supporting agricultural activities and ensuring water availability for the surrounding community. With moderate risk assessment and ongoing monitoring and maintenance efforts, this structure represents a valuable asset in the region's water resource infrastructure, contributing to sustainable water use and management practices.

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.
