Summary

This Earth-type dam stands at a height of 35 feet with a structural height of 40 feet and a length of 330 feet. With a storage capacity of 3460 acre-feet and a normal storage of 2560 acre-feet, Eggleston serves the primary purpose of irrigation, with additional recreational benefits.

Despite its fair condition assessment as of July 2020, Eggleston poses a high hazard potential, with a risk assessment rating of 2, indicating a significant level of risk. The dam lacks a spillway and features slide and uncontrolled outlet gates for water release. While it is regulated, permitted, and inspected by the Colorado Department of Water Resources, the dam's maintenance and risk management measures are not specified in the available data.

Given its location in Delta County, Colorado, Eggleston plays a crucial role in water resource management and agricultural irrigation in the region. As a significant infrastructure for the local community, ongoing monitoring, maintenance, and risk mitigation efforts are essential to ensure the safety and functionality of Eggleston for both irrigation and recreational purposes.

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.
