Summary
is a privately owned earth dam located in Lovedale, Harper County, Oklahoma. Constructed in 1955 by the USDA NRCS, this dam serves multiple purposes, including flood control and water storage on the TR-Sand Creek. With a height of 31 feet and a hydraulic height of 35 feet, Collier Warren C. has a storage capacity of 1155 acre-feet, with a normal storage level of 240 acre-feet.
Managed by the OWRB, this low-hazard dam has a controlled spillway and one outlet valve. Despite its age, Collier Warren C. remains in good condition and has a very high risk rating of 1. Regular inspections are conducted every five years to ensure its structural integrity and safety. As a vital water resource in the region, this dam plays a crucial role in managing water flow and mitigating flood risks in the area.
Water resource and climate enthusiasts will appreciate the engineering and management aspects of Collier Warren C. The collaboration between private ownership, federal agencies, and state regulators showcases the importance of effective water infrastructure in Oklahoma. With its strategic location and functional design, this dam serves as a testament to the ongoing efforts to safeguard water resources and enhance resilience to climate-related challenges in the region.

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.
