Instream Habitat Restoration

Healthy watersheds contain expansive streamside forests and rivers and streams that flow freely. Healthy watersheds produce cool, clean water. And healthy watersheds accommodate the high flow events during storms and during snow melt by occupying side channels, streamside ponds, and low lying floodplain areas.

Decades of land and water management and development have constrained many of these characteristics through the Rogue River Watershed Council’s area.

Rogue River Watershed Council identifies conditions in and along streams that limit habitat quality for fish and wildlife and water quality. We reach out to landowners and land managers to discuss these limiting factors, develop approaches to reduce or eliminate the impact, and implement restoration projects to address them.

Forty years ago, the Army Corps of Engineers had planned on roughly four miles of Elk Creek to be reservoir bottom.  But in 2008, the partially completed Elk Creek Dam was notched, making those stretches of Elk Creek immediately upstream of the former dam location a high priority for restoration. Because these stream reaches have been highly altered, there is plenty of restoration need.

A team of agencies and organizations, including Rogue River Watershed Council, developed over forty individual restoration actions along this stretch of Elk Creek.  We plan to address a ten-foot high berm at river mile 5.6 during the summer of 2017. This berm keeps the creek from reaching large expanses of floodplain during storm events. These floodplain areas are essential.  They serve as fish habitat during storms and they allow fine sediment to drop out of the water column.  Side channels and ponds form on these floodplains and these become very important winter habitats for young salmon and steelhead. Log jams accumulate along these floodplain areas.  Over time, water rushing past these log jams creates deep scour pools and accumulates large expanses of clean gravels.

Once this restoration project is implemented, we will develop more refined designs for the other actions identified in the Elk Creek Plan.


Sugarpine Creek (2016 & 2017)

Sugarpine Creek is a headwater tributary of Elk Creek (near the town of Trail).  The creek is limited by a lack of logs that create deep pools and capture large pockets of clean gravel.  The creek also has degraded streamside forest conditions with some sections overgrazed by livestock and others overrun by blackberries.

From fall of 2016 through summer of 2017, Rogue River Watershed council, a private landowner, Bureau of Land Management, Oregon Department of Fish and Wildlife, and US Forest Service will team to address these limiting factors in Sugarpine Creek. Our activities will include:

Sugarpine Creek Side Channel

Sugarpine Creek Side Channel

  • removing blackberries and establishing a variety of native trees and shrubs along 1,500 feet of streambank to create shade;
  • installing 13 log jams to create deep pools and store large pockets of spawning gravels;
  • stabilizing 300 feet of severely eroding cut bank in a side channel to limit fine sediments that smother fish eggs; and
  • fencing a mile of the creek to keep livestock from grazing on streamside plants to encourage more shade and lower levels of streambank erosion.

Sugarpine Creek is home to large numbers of Coho Salmon and steelhead. With modest habitat restoration, Rogue River Watershed Council knows that those populations will be better able to survive severe weather and hydrologic conditions, making Sugarpine Creek a more dependable source of young salmon and steelhead.

During summer of 2017, Rogue River Watershed Council, Bureau of Land Management, Oregon Department of Fish and Wildlife, and US Forest Service will team to install 13 log jams, stabilize an eroding cut bank, remove blackberries and install fencing.


Jones Creek Fish Passage (2015 & 2016)

Over the past five years, Stream Restoration Alliance of the Middle Rogue has removed three fish passage barriers (see 2010 project, below), allowing migratory fish to reach much further up the creek than they had been able to in past years (Jones Creek Fish Monitoring).

During the summer of 2015, Rogue River Watershed Council removed a fourth barrier (an unused, eight-foot high, concrete dam) from the East Fork of Jones Creek.

The fifth barrier in the Jones Creek system is found at the Mina Lane crossing. During summer of 2015, Rogue River Watershed Council and a handful of volunteers waded through the poison oak to create a weir that forms a large pool at the downstream end of the road culvert. This weir backs water up to the downstream end of the culvert. In July of 2016, Oregon Department of Fish and Wildlife completed the project by installing baffles to make water deeper (and slower, particularly during storms). In concert, the weir and baffles allow migrating fish to be able to easily swim past the road crossing on their way upstream.

During July, August, and early September of 2015, Rogue River Watershed Council managed the removal of two dams on Evans creek for Geos Institute.  The Fielder and Wimer Dams were severe impediments to fall Chinook Salmon, Coho Salmon, summer and winter steelhead, and Pacific Lamprey since their construction over 80 years ago.

Both of these dams were listed by Oregon Department of Fish and Wildlife as among the top-10 most important fish passage barriers to address in Oregon. Excellent water quality and habitat quality, as well as the amount of habitat available, in upper Evans Creek, West Fork Evans Creek, and several of the smaller tributaries were the primary reasons for the state level priority.

Salmon, steelhead, Pacific Lamprey and other migratory fish can easily swim through the lower 10 miles of Evans Creek on their way to as much as 70 miles of habitat for the first time since the 1930’s.  This easy access to such a large amount of cold, clear water will lead to healthier native fish populations.

This project was designed to improve native fish passage at two locations on Larson Creek in Medford, Oregon. Construction took place at two culvert crossings owned by the City of Medford with two private landowners at each site. At the Ellendale Drive (RM 0.25) site, there was a 2.5” to 3” drop at the culvert exit and shallow sheet flow within the culvert which prevented adult and juvenile salmonid passage during most flows. At the Black Oak Drive (RM 0.5) site, the culvert had a ramped exit that created a hydraulic jump and shallow sheet flows within the culvert which prevented fish passage at most flows. The solution at both culverts was to construct an engineered riffle to eliminate the drop at the culvert exits and to provide baffling inside the culverts to provide adequate flow depth during low flows. This project provided access to more than three miles of spawning and rearing habitat for steelhead and 2 miles of spawning and rearing habitat for coho.


Jones Creek – Railroad Culvert  (2010)

Jones Creek is the most important summer steelhead producing stream in the Middle Rogue subbasin. Fish passage had been impaired on Jones Creek by two undersized culverts that concentrated water flow and downcut the stream channel at the mouth of the culverts. This resulted in a 2-3 foot jump into a high velocity culvert, preventing all juvenile passage to upstream spawning and rearing grounds.

In the summer of 2010, we restored fish passage on Jones Creek by implementing a roughened channel design. We rebuilt the channel to its original grade using materials intended to stay in place, removed invasive plants, and planted native trees and shrubs. In the first year after project completion, counts of out migrating juveniles have shown a 800% increase in fish that have made it above the culverts in comparison with the previous 5 year average documented by ODFW.

 West Branch Elk Creek Habitat Restoration (2010)

West Branch Elk CreekThe project site is located on West Branch Elk Creek in the Upper Rogue sub-basin. Large wood tree lengths and logs were placed in jams within a 1 mile stretch of West Branch Elk Creek. Large wood jams are effective in slowing high winter stream flows and scouring pools for young salmon and steelhead.

The large wood jams have slowed the velocity of water during high flow events. This has led to an increase in the volume of spawning gravels that have dropped out during high flows and are stored in the project site. Slower water velocities during the winter have allowed the jams to capture considerable smaller wood pieces and offer niches within the wood complex where fish can take cover during a flood event. Pools have been created by water scour under the large biomass of the wood jams and these pools contain overhead cover and complex collections of branches and smaller wood pieces optimum for juvenile salmonid rearing.


Hawk Creek Habitat Enhancement (2004)

Hawk Creek Before

Before

Hawk Creek is located in the Elk Creek watershed of the Upper Rogue sub-basin. Hawk Creek contains coho salmon, summer and winter steelhead and Cutthroat trout. Land use practices such as logging alongside streams and removal of woody material from the stream channel had resulted in degraded aquatic conditions by simplifying the stream channel, reducing spawning gravel, overwintering habitat and pools.

In 2004, ten structures composed of logs and boulders were placed in a 0.5 mile stretch of Hawk Creek and Elkhorn Creek to benefit fish habitat.

Hawk Creek After

After

By improving these limited conditions, coho salmon and steelhead were observed using newly-recruited gravel in a section that had previously been all bedrock. Surface water that formerly ran in a shallow sheet over bedrock now runs through gravel and cobbles in many locations, reducing solar radiation on surface waters. Nooks and crannies in and around gravels, cobbles, boulders and wood jams provides aquatic insect habitat, a critical aspect of a healthy watershed.
