Summary
Built in 1973 by the USDA NRCS, this earth dam stands at a height of 18 feet and spans 800 feet in length. With a storage capacity of 238 acre-feet, it serves as a crucial resource for the local ecosystem and wildlife.
Despite its low hazard potential, Lewis Lawson #4 has a moderate risk assessment, highlighting the importance of regular monitoring and maintenance. The dam has not been inspected since October 1978, and its condition remains unrated. With a spillway width of 60 feet and a maximum discharge of 270 cubic feet per second, it is essential to ensure that emergency protocols are in place to mitigate any potential risks.
As a key feature in the region's water resource management, Lewis Lawson #4 represents a vital habitat for fish and wildlife. With its historical significance dating back to the 1970s, it is crucial for stakeholders to prioritize regular inspections and risk assessments to maintain the dam's integrity and ensure the safety of surrounding communities and ecosystems.

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.
