Summary

Primarily used for irrigation, this earth dam structure stands at 47 feet tall and spans 1600 feet in length, providing essential water storage for the surrounding area. With a normal storage capacity of 12,736 acre-feet and a surface area of 493 acres, Lake Loveland plays a crucial role in supporting agricultural activities and water supply needs in the region.

Despite its age, Lake Loveland has been well-maintained, with a satisfactory condition assessment as of the last inspection in September 2020. However, being classified as a high hazard potential dam, it is important for regulatory agencies like the Department of Water Resources to ensure regular inspections, enforcement, and emergency preparedness measures are in place. With its scenic location near the Big Thompson River, Lake Loveland also offers recreational opportunities for visitors to enjoy its tranquil waters, adding to its significance as both a practical resource and a natural gem in the region.

As climate change continues to impact water resources, the role of reservoirs like Lake Loveland in managing water supply and risks becomes increasingly crucial. With its high risk assessment rating and regulated status, Lake Loveland serves as a reminder of the importance of proactive dam management and the need for continued monitoring and investment in infrastructure to safeguard against potential hazards and ensure sustainable water management for future generations.

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.
