The reservoir has a hydraulic height of 24 feet and a structural height of 28 feet, with a storage capacity of 18 acre-feet and a maximum storage of 9 acre-feet. Situated along the South Fork of Cottonwood Creek, the reservoir covers a surface area of 9 acres and has a low hazard potential with a poor condition assessment.
Despite its limited storage capacity, South Cottonwood Creek Reservoir serves as a vital resource for water supply and wildlife habitat in the J. Lawrence Ranch area. The dam, primarily owned and operated by the Bureau of Land Management, plays a crucial role in maintaining the ecological balance and supporting local agriculture. However, the reservoir's poor condition assessment highlights the need for regular maintenance and inspection to ensure its continued functionality and safety for the surrounding community.
With its historical significance dating back to the early 1960s, South Cottonwood Creek Reservoir stands as a testament to the importance of water resource management in arid regions like Oregon. As climate change continues to impact water availability and quality, the proper stewardship of reservoirs like South Cottonwood Creek becomes increasingly essential in safeguarding against drought, wildfires, and other environmental challenges.
