Summary
Completed in 1947, this earth dam stands at a height of 18 feet and stretches 224 feet in length, with a maximum storage capacity of 401 acre-feet and a normal storage capacity of 206 acre-feet. The dam is situated on the Big Branch-TR river and is regulated by the Colorado Division of Water Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
Despite being classified as having a low hazard potential, Harris Brothers and Boone #2 is considered to have a high risk level due to its condition assessment of being satisfactory and its location in a high-risk area. The dam has a spillway width of 65 feet and a maximum discharge capacity of 2952 cubic feet per second. The last inspection of the dam was conducted in September 2015, with a regular inspection frequency of every 6 years. With its critical role in irrigation in the region, stakeholders and water resource enthusiasts closely monitor the safety and operation of Harris Brothers and Boone #2 to ensure the continued reliability of its water management functions.
As an integral part of the water infrastructure in Colorado, Harris Brothers and Boone #2 serves as a vital resource for agricultural irrigation in the area. With its historical significance and ongoing regulatory oversight, this dam plays a crucial role in ensuring water availability for the local community. As climate change impacts water resources, the management and maintenance of structures like Harris Brothers and Boone #2 become increasingly important to guarantee sustainable water usage and resilience in the face of changing environmental conditions.

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.
