Summary
This private dam, primarily built for stock purposes, stands at a height of 22 feet with a hydraulic height of 18 feet. It has a storage capacity of 109.9 acre-feet and covers a surface area of 10 acres, drawing water from a drainage area of 46 square miles.
Despite its low hazard potential and moderate risk assessment rating, Hinson Lake Dam has not been state-regulated, permitted, or enforced upon. The dam is of earth construction with a buttress core type, featuring an uncontrolled spillway. The last inspection date was in July 2020, with a scheduled inspection frequency of every 5 years. The dam's condition assessment remains unrated, with no emergency action plan in place.
For water resource and climate enthusiasts, Hinson Lake Dam offers a fascinating glimpse into a privately owned structure that plays a vital role in local water management and conservation efforts. Its unique design and purpose highlight the diverse ways in which dams can serve communities, from providing fire protection to creating habitats for small fish populations. Despite its relatively low hazard potential, the dam's risk assessment underscores the importance of regular monitoring and maintenance to ensure the safety and integrity of the structure for both the environment and nearby residents.

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.
