Summary
Built in 2008, this earth dam stands at a height of 12.5 feet and has a storage capacity of 183 acre-feet, with a surface area of 35.48 acres. The primary purpose of this dam is to provide habitat for fish and wildlife, specifically in the Little Pine Ridge Creek.
Managed by the SEO regulatory agency in Wyoming, the Enlargement of The Shallow has a low hazard potential and is in fair condition as of its last inspection in May 2018. With a moderate risk assessment level, this dam is equipped with an uncontrolled spillway measuring 100 feet in width and a valve outlet gate. The dam's design and construction were overseen by designer Ralph Goodsen, and it is subject to state permitting, inspection, and enforcement to ensure its safety and compliance with regulations.
Overall, the Enlargement of The Shallow serves as an important resource for supporting local fish and wildlife populations in Wyoming. Its strategic location near the I-90 highway and the Little Pine Ridge Creek makes it a valuable asset for conservation efforts and environmental protection in the region. The careful management and maintenance of this dam demonstrate a commitment to sustainable water resource management and climate resilience in the area.

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.
