Summary
With a primary purpose of fire protection, stock, or small fish pond, the dam also serves recreational activities. Standing at a hydraulic height of 6 feet and a structural height of 16 feet, it has a length of 603 feet and a storage capacity of 100 acre-feet.
Despite being classified as a low hazard potential structure, Tobin Lake Dam is not currently rated for its condition. The dam does not fall under state jurisdiction or regulation, with no inspections or enforcement actions reported. While it lacks certain safety assessments such as an Emergency Action Plan (EAP) or risk management measures, the dam continues to play a vital role in the local water resource management and support various activities in the area.
Water resource and climate enthusiasts may find Tobin Lake Dam an intriguing site to explore, given its historical significance and contributions to the community. As a privately owned structure, its role in fire protection and recreational activities adds to the overall landscape of water resource management in Arkansas. While it may not have the same level of regulatory oversight as other dams, its presence along the Cossatot River highlights the importance of maintaining and monitoring such infrastructure for the benefit of both residents and the environment.

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.
