Summary

This Earth-type dam, completed in 1911, stands at a height of 50 feet and has a maximum storage capacity of 44,650 acre-feet. With a normal storage capacity of 21,695 acre-feet and a surface area of 2,660 acres, Milton Lake plays a crucial role in providing water for agricultural activities in the region.

Despite its age, Milton Lake remains in satisfactory condition, as indicated by its last inspection in December 2020. The dam has a high hazard potential but is well-maintained and meets regulatory standards set by the Colorado Department of Water Resources. In the event of an emergency, the dam has protocols in place to ensure public safety, although specific details about emergency action plans are not provided in the data.

With its strategic location on the Beebe Seep Canal and its vital role in water resource management, Milton Lake serves as a significant asset for the community of Kersey and surrounding areas. As a key component of the irrigation infrastructure in Weld County, this reservoir contributes to the sustainability of agriculture in the region while adhering to state regulations and ensuring safe operations for all stakeholders involved.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
