Summary

Built in 1948 by private owners, this Earth-type dam stands at 18 feet tall with a hydraulic height of 16 feet and a length of 200 feet. It has a storage capacity of 80 acre-feet, with a normal storage of 55 acre-feet and a maximum discharge of 85 cubic feet per second. Despite being non-regulated by the state and having a low hazard potential, Haven remains a popular spot for water resource and climate enthusiasts seeking outdoor recreational activities in Calhoun County.

Owned and operated by a private entity, Haven serves primarily recreational purposes, offering visitors a picturesque setting for various outdoor activities. Its location on TR Terrapin Creek within the scenic landscape of Alabama's Calhoun County provides an ideal environment for water enthusiasts to enjoy kayaking, fishing, and other water-related recreational pursuits. The dam's history and design contribute to its appeal as a destination for those interested in exploring the intersection of water management and natural beauty.

While Haven may not be subject to state regulation or inspection, its low hazard potential and unblemished safety record make it a reliable and attractive destination for outdoor enthusiasts in the region. With its modest height and storage capacity, the dam offers a tranquil setting for recreation without the concerns typically associated with larger, more heavily regulated structures.

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.
