Summary
Built in 1952, this earth dam stands at 32 feet high and stretches 254 feet in length. The primary purpose of Whiteley-Nelson is for irrigation, with additional functions including fire protection, stock, or small fish pond. It has a storage capacity of 526 acre-feet, with a normal storage level of 426 acre-feet and a surface area of 25 acres.
Despite being classified as having a low hazard potential, the dam is deemed to be in fair condition as of the last assessment in July 2017. It has a moderate risk rating and is subject to state regulation, inspection, and enforcement by the Colorado Division of Water Resources. The dam has an uncontrolled spillway and a maximum discharge capacity of 1036 cubic feet per second, with Lawson Creek-Tr running nearby. The surrounding area has a drainage area of 1 square mile, making Whiteley-Nelson a vital water resource for the local community.
For water resource and climate enthusiasts, Whiteley-Nelson offers a fascinating glimpse into the intersection of human infrastructure and natural ecosystems. As an essential irrigation structure in Colorado, its management and maintenance play a crucial role in both water supply for agricultural purposes and ensuring the safety of downstream areas. The dam's historical significance, engineering design, and operational capabilities make it a noteworthy site for those interested in sustainable water management practices and the impacts of climate change on water resources.

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.
