Summary

Built in 1902, this Earth-type dam stands at a height of 12 feet and has a length of 50 feet, providing water storage for irrigation purposes. With a normal storage capacity of 873 acre-feet and a maximum storage of 1305 acre-feet, Lindenmeirs serves as a critical water resource for the region.

Managed by the Colorado Division of Water Resources (DWR), Lindenmeirs is subject to state regulation, permitting, inspection, and enforcement. The dam has a low hazard potential and is in satisfactory condition, as assessed during the last inspection in June 2018. Although the spillway is uncontrolled, the dam's risk assessment is moderate, indicating the need for ongoing risk management measures to ensure the safety and integrity of the structure.

Situated along the Cache La Poudre River, Lindenmeirs offers opportunities for recreational activities in addition to its primary function as an irrigation reservoir. With its historical significance and vital role in water management, Lindenmeirs stands as a testament to the enduring impact of water resource infrastructure on the natural landscape and local communities in Colorado.

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.
