Summary

Completed in 2004 by JOHN GEORGE and Agricultural Engineering Associates, this structure stands at 13.6 feet tall and spans 1754 feet in length. With a storage capacity of 279.62 acre-feet and a drainage area of 0.65 square miles, E-2 plays a crucial role in managing water flow and mitigating flood risks in the region.

The dam's spillway, classified as uncontrolled, has a width of 40 feet to handle a maximum discharge of 500 cubic feet per second. Despite its low hazard potential, E-2 is not currently rated for condition assessment nor does it have an Emergency Action Plan in place. However, with a moderate risk rating, it is imperative for stakeholders to consider implementing risk management measures and ensuring the dam's structural integrity for long-term resilience against potential hazards.

As water resource and climate enthusiasts, it is important to recognize E-2 as a vital infrastructure contributing to the protection of the surrounding communities from flooding events. By understanding its design, purpose, and current risk assessment, stakeholders can work towards improving the dam's safety measures and emergency preparedness to safeguard lives and property in the face of changing environmental conditions.

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.
