Summary

Joe is a privately owned earth dam located in Tillman, Oklahoma, near the city of Manitou. Built in 1960, this dam stands at a height of 27 feet and has a storage capacity of 134 acre-feet. The primary purpose of Horton Dr. Joe is classified as "Other", with a spillway width of 1 foot and a controlled spillway type.

Managed by the Oklahoma Water Resources Board, Horton Dr. Joe is subject to state regulation, inspection, and enforcement. Despite being categorized as having a low hazard potential, the dam is considered to have a very high risk due to its condition assessment being marked as "Not Rated". The last inspection date for Horton Dr. Joe was in November 2010, with an inspection frequency of 5 years.

Water resource and climate enthusiasts will find Horton Dr. Joe's risk assessment and management measures intriguing. With its unique design and location along the TR-DEADMAN CR river/stream, this dam serves as a crucial structure for water storage and regulation in the region. The data provided for Horton Dr. Joe offers a glimpse into the complex world of dam management and highlights the importance of maintaining infrastructure for water resource sustainability.

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.
