Summary

Completed in 1948, this earth dam stands at a height of 60 feet and spans a length of 5080 feet, creating a reservoir with a storage capacity of 113,600 acre-feet. The dam operates on Cedar Creek and serves the primary purpose of irrigation for the surrounding area.

Managed by the Colorado Division of Water Resources, Point of Rocks has a high hazard potential but is currently assessed as being in satisfactory condition. With a hydraulic height of 86 feet and a maximum discharge capacity of 8,000 cubic feet per second, the dam plays a crucial role in regulating water flow and providing essential irrigation water for agricultural activities in the region. Regular inspections and enforcement ensure the safety and integrity of this vital water resource infrastructure.

Located in the city of Iliff, Point of Rocks is a key component of the water management system in Colorado, contributing to the efficient distribution of water resources for agricultural purposes. Its strategic location and operational efficiency make it a significant asset in the region's water supply network, highlighting the importance of sustainable water resource management in the face of climate challenges and variability.

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.
