Summary

The earth dam, completed in 1983, stands at 17 feet in height and has a storage capacity of 277 acre-feet. The dam serves a primary purpose that is classified as "Other," and its spillway type is labeled as "Controlled," with a width of 1 foot.

Despite being categorized as having a low hazard potential, Haynie Wk is considered to have a very high risk level, with a risk assessment rating of 1. The dam is under state regulation by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement processes in place. The last inspection of the dam took place in July 2002, with a scheduled inspection frequency of every 5 years.

Water resource and climate enthusiasts may find Haynie Wk intriguing due to its location in a region with a high risk of flooding, as indicated by its risk assessment rating. The dam's significance lies in its role in managing water resources and preventing potential disasters in the area. The data provided offers valuable insights into the structure and function of this important infrastructure, highlighting the importance of proper regulation and maintenance to ensure public safety and environmental protection.

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.
