Summary

Built in 1970, this earth dam stands at a height of 24 feet and has a maximum storage capacity of 61 acre-feet. Its primary purpose is for irrigation, but it also serves as a source of fire protection, stock watering, and fish and wildlife habitat.

Despite its low hazard potential, Coyte's condition assessment in 2017 was deemed unsatisfactory. With a moderate risk rating, the dam requires regular inspections and maintenance to ensure its safety and functionality. The spillway, with a width of 25 feet, is uncontrolled, and the maximum discharge capacity is 864 cubic feet per second.

Coyte plays a crucial role in managing water resources in the region, specifically for agricultural purposes. Its location on Big Grizzly Creek-TR and proximity to Sacramento District highlights its significance in the local water infrastructure. As a climate enthusiast, understanding the condition and risk factors associated with Coyte can provide valuable insights into the challenges and opportunities in maintaining water resources in a changing climate.

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.
