Summary
This earth dam stands at a height of 27 feet and has a length of 580 feet, creating a reservoir with a storage capacity of 330 acre-feet. Despite its low hazard potential, the dam is classified as having a very high risk due to its condition not being rated and lacking emergency action plans.
Managed by the Oklahoma Water Resources Board, Gormly Alger is inspected every 5 years to ensure its structural integrity and safety measures. The dam features a controlled spillway with a width of 1 foot and a single valve outlet gate for water release. While the dam's primary purpose is listed as "Other," it serves as a vital infrastructure for water resource management in the region, supporting various purposes such as irrigation and flood control. The risk assessment for Gormly Alger reflects the need for improved management measures to address potential safety concerns.
With its strategic location and function within the watershed, Gormly Alger plays a crucial role in water resource management in Okfuskee County. As climate change continues to impact water availability and extreme weather events, the importance of maintaining and upgrading infrastructure like Gormly Alger becomes increasingly vital. Water resource and climate enthusiasts will find Gormly Alger to be a fascinating case study in dam management and the intersection of infrastructure, environmental conservation, and climate resilience.

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.
