Summary

The dam serves primarily for recreational purposes, including fish and wildlife pond activities, with a storage capacity of 400 acre-feet and a surface area of 16 acres. Despite its low hazard potential, the dam's condition assessment was rated as poor during its last inspection in 2016, indicating a need for maintenance and upkeep.

The dam, standing at a height of 25 feet and a length of 575 feet, is classified as an earth dam with a buttress core type. It sits on an unnamed tributary of Indian Creek, with a drainage area of 0.09 square miles. Despite its lack of a spillway, the dam's risk assessment is considered high, with a risk level of 2 out of 3. The surrounding area's congressman, Trey Hollingsworth (R), represents the district in which the dam is located, emphasizing the importance of proper oversight and maintenance to ensure public safety and environmental protection.

Given the dam's critical role in providing recreational opportunities and managing water resources in the area, it is essential for relevant authorities and stakeholders to address the dam's poor condition and high-risk assessment. Proper maintenance and risk management measures should be implemented to safeguard the dam's integrity, protect the surrounding environment, and ensure the safety of nearby communities and wildlife. By prioritizing these actions, Fowler Lake Dam North can continue to fulfill its recreational and water resource management functions effectively and sustainably.

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.
