Summary

The dam serves primarily for recreational purposes, providing a storage capacity of 175 acre-feet and a maximum storage of 210 acre-feet. With a low hazard potential, the dam is classified as an Earth type structure with a hydraulic height of 12 feet and a length of 856 feet.

Situated on Derrieusseaux Creek-TR, Clear Lake Dam is owned and operated by a private entity and is not regulated by the state. The dam has not been inspected or assessed for its condition, and there are no emergency action plans or inundation maps prepared for the site. Despite its relatively low hazard potential, the dam's lack of recent inspections and maintenance raises concerns for potential risks associated with its structural integrity.

In conclusion, Clear Lake Dam presents an intriguing case study for water resource and climate enthusiasts, highlighting the importance of regular inspections, maintenance, and emergency preparedness for dams, particularly those used for recreational purposes. The dam's location in Grant County, Arkansas, and its historical significance as a recreational site underscore the need for proactive risk management measures to ensure the safety and sustainability of the surrounding environment and community.

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.
