Summary
Completed in 1994, this earth-type dam stands at a structural height of 9 feet and has a length of 150 feet, providing a storage capacity of 75 acre-feet. Despite being classified as "Undetermined" in terms of hazard potential and "Not Rated" in condition assessment, the dam is subject to regular state inspection, enforcement, and permitting, ensuring its safety and compliance with regulations.
Situated in the Omaha District, Hansen, Collin 94-29-71md serves a primary purpose other than flood control or water supply, with no associated structures and a drainage area of 0. While lacking specific details on spillway type, discharge capacity, or emergency action plan preparedness, the dam's condition and risk management measures remain undisclosed. With its geographical coordinates at 41.58093703 latitude and -112.1779317 longitude in a remote location with no nearby city, the dam continues to be monitored for any potential risks or hazards.
Owned privately and managed by the state of Utah, Hansen, Collin 94-29-71md embodies the complex regulatory framework governing water resources and climate adaptation. As water resource and climate enthusiasts explore the intricacies of dam infrastructure and management, this dam serves as a case study in the ongoing efforts to balance water security, regulatory oversight, and environmental protection. With its history dating back to 1994 and ongoing state supervision, Hansen, Collin 94-29-71md stands as a testament to the importance of sustainable water management practices in an era of changing climate dynamics.

Dam Data Reference
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.
