Summary

With a rockfill dam standing at 18 feet high and a hydraulic height of 130 feet, this reservoir boasts a storage capacity of 2,300 acre-feet and a surface area of 44 acres. Managed by the Federal Energy Regulatory Commission, Lake Hope serves as a vital water resource in the region for both human and ecological needs.

Despite its age, Lake Hope maintains a low hazard potential and a moderate risk assessment rating, indicating a stable and secure infrastructure. The dam's uncontrolled spillway and proximity to the Lake Fork River ensure efficient water management and environmental sustainability. While the condition assessment is currently unavailable, regular inspections by FERC and state regulatory agencies uphold the dam's integrity and safety standards. Lake Hope stands as a testament to responsible water resource management in the face of climate challenges.

As a critical piece of Colorado's water infrastructure, Lake Hope stands as a symbol of innovation and sustainability in the face of changing climate patterns. Its role in hydroelectric power generation, coupled with its multi-purpose functionality, underscores the importance of adaptive water resource management strategies. With state jurisdiction and regulatory oversight in place, Lake Hope continues to be a beacon of hope for water resource and climate enthusiasts alike, showcasing the intersection of natural beauty and human ingenuity in the pursuit of a sustainable future.

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.
