Summary
Walnut Creek. Completed in 1960, this Earth-type dam with a stone core spans 190 feet in length and reaches a height of 30 feet. With a maximum storage capacity of 90 acre-feet and a normal storage level of 50 acre-feet, Dannels Ken serves various purposes beyond flood control, making it a versatile asset in the region's water management.
Despite its age, Dannels Ken maintains a low hazard potential and has not been rated for its condition as of yet. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 140 cubic feet per second. Managed by the OWRB and subject to state jurisdiction and regulatory oversight in Oklahoma, Dannels Ken has undergone regular inspections, with the last recorded inspection dating back to July 2005. The risk assessment for this structure has been classified as very high, highlighting the importance of ongoing monitoring and maintenance to ensure its continued safety and functionality for the surrounding community.
As an essential component of the local water infrastructure, Dannels Ken plays a critical role in managing water resources and mitigating flood risks in the area. With its strategic location along TR. Walnut Creek and its capacity to store and release water as needed, this Earth-type dam continues to serve the community effectively despite its age. As climate change impacts become more pronounced, structures like Dannels Ken will be vital in adapting to changing hydrological patterns and safeguarding the region's water supply for the future.

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.
