Summary

Completed in 2003, this buttress-type dam stands at a height of 34 feet and spans a length of 265 feet, offering a storage capacity of 133 acre-feet. With a normal storage volume of 73 acre-feet, the dam covers a surface area of 9.75 acres and serves a drainage area of 1.2 square miles.

Equipped with an uncontrolled spillway measuring 130 feet in width, Gutierrez Ranch Dam has one uncontrolled and one valve outlet gate, ensuring regulated water flow. While its hazard potential and condition assessment are not available, the dam has a moderate risk rating of 3. The last inspection in November 2015 indicated that the dam's condition was not rated, with no emergency action plan (EAP) prepared or updated. Despite being privately owned, the dam is not under state regulation or jurisdiction, highlighting its unique status in the portfolio of water resource structures within the area.

For water resource and climate enthusiasts, Gutierrez Ranch Dam offers a fascinating case study of a privately owned recreational structure that contributes to the local landscape's hydrological dynamics. With its modern design and moderate risk rating, the dam presents an intriguing intersection of human intervention and natural water systems. Further research and monitoring of the dam's performance and safety protocols could provide valuable insights into sustainable water management practices in the region, making Gutierrez Ranch Dam a noteworthy subject for ongoing study and analysis.

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.
