Summary
Built in 2004 by designer Hugh Lowham, this irrigation dam stands at a height of 32 feet and has a hydraulic height of 27 feet. With a storage capacity of 56 acre-feet and a surface area of 4.1 acres, Boon serves multiple purposes including fire protection, stock, and irrigation. Despite its low hazard potential, the dam's condition assessment in 2019 rated it as poor, indicating a need for maintenance and repair.
Boon's spillway type is uncontrolled with a width of 83 feet, and it is equipped with a single valve outlet gate. The dam's drainage area is 0.03 square miles with a maximum discharge capacity of 1163 cubic feet per second. The risk assessment for Boon categorizes it as moderate, highlighting the importance of regular inspections and risk management measures to ensure the safety and functionality of the structure. Overall, Boon is a key component of water resource management in the area, providing vital irrigation and other benefits to the local community.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
