Summary

Constructed in 1956, this earthen dam structure stands at a height of 29 feet with a hydraulic height of 22 feet, providing a storage capacity of 130 acre-feet. With a surface area of 10 acres and a drainage area of 11 square miles, the lake offers a serene setting for outdoor enthusiasts to enjoy activities such as fishing, wildlife viewing, and fire protection in the surrounding area.

Managed by the Colorado Department of Water Resources, Broadacre Lake is regulated, permitted, inspected, and enforced to ensure compliance with safety standards. The dam's spillway type is uncontrolled, with a spillway width of 17 feet to manage potential overflow. Despite being classified as having a significant hazard potential, the dam is currently in fair condition according to a 2018 assessment. With a moderate risk rating, Broadacre Lake provides a valuable recreational and environmental resource for the community and visitors to enjoy.

As part of the Sacramento District, Broadacre Lake is situated in the picturesque city of South Fork, offering a tranquil retreat for water resource and climate enthusiasts. With a maximum discharge capacity of 100 cubic feet per second, the lake provides not only a recreational escape but also serves practical purposes such as stock watering and small fish pond management. With its beautiful landscape and well-maintained facilities, Broadacre Lake is a destination worth exploring for those seeking to connect with nature and appreciate the importance of sustainable water resource management.

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.
