Abernethy Creek Park is located at Abernethy Road and John Adams Street. Since 2004, the GOCWC and friends have dedicated many hours to remove invasive plants and planted native species in the upland areas of Abernethy Creek. The Oregon City High School Junior ROTC has been a great partner and have committed to come out on Earth Day or there abouts each April.
The GOCWC received a grant from the Oregon Watershed Enhancement Board in June, 2018 to hire a contractor work in the steep slope bank areas where it is not suitable for volunteers. The combined volunteer and reforestation contractor work will create healthy riparian vegetation on the banks of Abernethy Creek to help reduce stream bank erosion and provide shade to lower water temperatures for fish.
