Summary
Gary is a privately owned Earth dam located in Alva, Oklahoma, along the TR TURKEY CR river. Constructed in 1986 by the USDA NRCS, this dam stands at a height of 27 feet and has a storage capacity of 137 acre-feet. With a low hazard potential and a very high risk assessment rating, it is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, permitting, and enforcement to ensure its structural integrity and safety.
Despite its modest size, Lott Dr. Gary plays a crucial role in managing water resources in the region, with a drainage area of 1.13 square miles and a maximum discharge capacity of 1441 cubic feet per second. The dam's controlled spillway and single valve outlet gate help control water flow, while its Stone core and Soil foundation provide stability. While its condition is currently not rated, the dam's risk management measures are under continuous evaluation to mitigate any potential threats and ensure the safety of surrounding communities.
As a key component of the local water infrastructure, Lott Dr. Gary serves a primary purpose of "Other" and is designed to meet state regulatory standards. With its strategic location and operational history, this dam stands as a testament to the ongoing efforts to balance water resource management and climate resilience in Oklahoma, under the supervision of the Natural Resources Conservation Service and state authorities.

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.
