Summary

This reservoir, completed in 1954, serves primarily for recreational purposes with a dam height of 30 feet and a hydraulic height of 22 feet. The earth dam spans 483 feet in length and has a storage capacity of 395 acre-feet, providing ample opportunities for boating, fishing, and other outdoor activities in the area.

The dam on Muddy Creek is regulated by the Colorado Department of Water Resources, ensuring proper inspection, permitting, and enforcement measures are in place for its operation and maintenance. Despite its low hazard potential and fair condition assessment, a moderate risk rating of 3 indicates some level of potential for risk management considerations. The reservoir covers 35 acres with a drainage area of 2 square miles, offering a serene escape for water resource and climate enthusiasts to enjoy the beauty of Grand County, Colorado.

With a spillway width of 54 feet and a maximum discharge capacity of 1992 cubic feet per second, Muddy Creek provides a vital recreation spot while also serving as a controlled water resource in the region. Its location within the Omaha District adds to its significance, attracting visitors who appreciate the natural beauty and recreational opportunities offered by this picturesque setting along the Muddy Creek.

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.
