Summary

Constructed in 1950 by USDA NRCS, this earth dam structure stands at a height of 25 feet and has a maximum storage capacity of 130 acre-feet. With a low hazard potential and satisfactory condition assessment, Slinde serves as a vital water source in the region, providing water for irrigation, fire protection, stock, and small fish ponds.

Situated along Dry Creek-TR, Slinde is regulated by the Colorado Department of Water Resources, with state oversight for permitting, inspection, and enforcement. The reservoir spans 12 acres with a drainage area of 0, featuring an uncontrolled spillway type and a moderate risk assessment rating of 3. Despite its age, Slinde remains a reliable water source with its last inspection conducted in 2013, meeting guidelines for risk management and emergency preparedness.

Managed by the Natural Resources Conservation Service, Slinde is a crucial component of the local water infrastructure in Longmont, contributing to the sustainable use of water resources in the region. With its strategic location and modern design features, Slinde continues to play a significant role in supporting agricultural activities and ensuring water security for the community, while maintaining a strong focus on environmental conservation and risk mitigation.

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.
