Rebuilding along the McKenzie River after the Holiday Farm Fire provides an opportunity to promote, establish and enforce measures that will protect and enhance the McKenzie and its riparian zones. Before the fire, houses in much of the burn corridor encroached on the river, altering its native ecosystem by outright removal of riparian vegetation and replacement with tiled patios, lawns and English ivy.
In response to questions about the county’s role, Land County Planning Supervisor Keir Miller offered the following: “As we work with landowners [who live] along the McKenzie, we are encouraging them to relocate further away from the river. Staff has also been working with EWEB to permit a subsidy program to incentivize folks to move back from the river. I know MRT [McKenzie River Trust], MWC [McKenzie Watershed Council] and others are also working on programs to support native replanting. As far as code enforcement goes, we will investigate violations as they arise, and we will also be developing an app for river guides and others to report violations on their phones in real time…”
Research by David Pillrod, an ecologist with the U.S. Geological Survey, shows that the loss of riparian vegetation can lead to higher water temperatures, increased erosion and sedimentation, which negatively affect amphibian and insect larvae for several years and up to decades after a high severity fire like the Holiday Farm Fire.
Scientific studies have shown that the climate crisis has stressed fish that depend on cold water, such as our native salmon, further threatening their survival. Restoring the McKenzie River, the source of Eugene’s drinking water, and making sure the rebuilding efforts do not harm — and actually improve — the riparian areas and waterways are key if we want the river and the life it holds to survive and become more resilient. Debris, toxic ash and sediment from the fire and from rebuilding materials and activities can impact the water quality for drinking, fish and other wildlife. Many miles of the river have suffered from harmful algae blooms, induced by encroachment and runoffs of toxic materials, long before the fire added to the harm.
EWEB’s Pure Water Partners program is a group of organizations, including the McKenzie Watershed Council, McKenzie River Trust, Cascade Pacific Resource Conservation and Development, Metropolitan Waste Management, Soil and Water Conservation District, U.S. Forest Service and others, that “support and reward McKenzie landowners who protect high quality land along the river.” Owners may contact EWEB for an assessment of their property and proposed erosion control and replanting with native vegetation.
EWEB’s water quality supervisor, Karl Morgenstern, says the utility is working with almost 300 landowners impacted by the fire. And the Bonneville Environmental Foundation has provided thousands of native plants for the restoration effort. To help pay for the recovery EWEB has assessed a residential and commercial Watershed Recovery Fee based on meter size, effective mid-2021.
Helping to ground the Holiday Farm recovery project, Northwest Youth Corps has been essential in the aftermath cleanup and in constructing measures to control the erosion of toxic sediments. The corps is a nonprofit modeled on the Conservation Civilian Corps that, its Executive Director Jeff Parker says, offers teens an opportunity to “learn, grow and experience success” while assisting in fire recovery, trail building and other hands-on projects.
Instead of using commercial wattles — long tubular sediment catchers stretched along the riverbank — made from plastic netting and non-native plants, Youth Corps workers have constructed ones made of jute and native willow twigs and branches, and installed them. They have also set up sediment fences and have been reseeding burned areas with native species.
In the process Kris Stenshoel, an EWEB environmental specialist, has tutored these young workers, who are already, she says, “environmentally conscious and education driven,” about the function and importance of native plants and riparian and watershed ecosystems.
Most would agree they want a healthy river that supports wildlife and provides clean drinking water, but many don’t understand the role riparian areas with native trees, shrubs and ground cover play in a river’s health. Educating people who live along the river about how to be a partner in a healthy restoration effort is essential, especially as hotter and drier springs and summers increase wildfire intensity and frequency and threaten farms, forests and wildlife.
The good news is there are tools, organizations and funding that can help restore the McKenzie and its banks in harmony with the river’s needs. Landowners and other interested parties can take advantage of that windfall, begin to heal the McKenzie River and get people back in their homes built back better.
