Summary
Fish and Wildlife Service. Built in 1936 by the U.S. Bureau of Biological Survey, this earth dam stands at a height of 13 feet and spans a length of 1045 feet along the Deep Creek-TR river or stream. The dam provides a storage capacity of 2075 acre-feet, with a low hazard potential and fair condition assessment as of the last inspection in 2017.
Over the years, Stewart Dam has undergone several modifications for hydraulic, seismic, and structural improvements in 1952 and 1995. It is equipped with other controlled outlet gates and is regulated by the Fish and Wildlife Service for operations, inspections, and enforcement. The dam is situated in a rural area with a low risk potential, and while it meets state regulatory standards, its Emergency Action Plan status and risk management measures are unspecified. With a relatively small drainage area of 15 square miles, Stewart Dam plays a crucial role in water resource management and climate resilience efforts in the region.

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.
