Summary
1 is a privately owned earth dam located in Torrington, Wyoming, along the North Laramie River offstream. Built in 1912, this irrigation dam stands at 30 feet tall and spans 1200 feet in length, with a storage capacity of 2805 acre-feet for various purposes including fire protection, stock, irrigation, and small fish pond management. Despite being regulated by the State of Wyoming and regularly inspected, the dam's condition was reported as poor during the last assessment in 2017.
With a low hazard potential and a moderate risk assessment rating, North Laramie Land Company No. 1 remains a crucial water resource infrastructure in Platte County, Wyoming. Although the dam's condition may be concerning, its role in supporting agricultural activities and ensuring water supply for the surrounding area underscores its importance. The presence of an uncontrolled spillway and a single valve outlet gate further highlight the need for continued monitoring and maintenance to mitigate any potential risks associated with this aging structure.
In the context of climate change and increasing water scarcity, the preservation and proper management of dams like North Laramie Land Company No. 1 are paramount. As water resource and climate enthusiasts, it is essential to advocate for sustainable practices that safeguard these vital infrastructure assets while also exploring innovative solutions to enhance their resilience in the face of evolving environmental challenges.

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.
