Summary
Built in 1960 by the USDA NRCS, this dam stands at a height of 25 feet and has a storage capacity of 76 acre-feet. With a low hazard potential and a moderate risk assessment rating, this dam serves as a vital infrastructure for water resource management in the area.
The dam, with a length of 240 feet and a surface area of 3 acres, plays a crucial role in controlling water flow and providing irrigation for the surrounding lands. Despite not being regulated or inspected by state agencies, Pearson #1 holds a significant position in the local water resource system. The spillway type is uncontrolled, with a width of 48 feet, ensuring that excess water is safely managed during heavy rainfall events.
Even though the dam's condition is not rated, its importance in water storage and flood control cannot be understated. With a risk assessment rating of moderate, it is essential for stakeholders and local authorities to pay attention to its maintenance and upkeep to ensure its continued functionality in the face of changing climate conditions. Pearson #1 stands as a testament to the intersection of water resource management and climate resilience in the region.

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.
