Summary
1 is a privately owned water resource structure located in Weston, Wyoming, along HWY. 450. Constructed in 1969 by Delbert E Robinson, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a hydraulic height of 13 feet and a structural height of 18 feet, the dam has a storage capacity of 197 acre-feet and covers a surface area of 19 acres. Despite its low hazard potential, the dam is in poor condition as of its last inspection in September 2017.
Situated on the WELL DRAW tributary of the Lodgepole Creek, South Lodgepole No. 1 plays a crucial role in flood risk reduction for the area. The dam has an uncontrolled spillway with a width of 100 feet and an outlet gate for controlled water release. Although it has not been modified over the years, the dam is subject to regular state inspection, enforcement, and permitting, as it falls under Wyoming's jurisdiction and is regulated by the State Engineer's Office.
With a moderate risk assessment rating of 3, South Lodgepole No. 1 requires attention to improve its condition assessment and ensure the safety and effectiveness of its operations. As climate change continues to impact water resources and infrastructure, enthusiasts and stakeholders in water management and climate resilience should monitor the maintenance and regulatory efforts concerning this vital water resource structure in Wyoming.

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.
