Nova Scotia Fish Habitat Assessment Protocol (NSFHAP)

Clean Nova Scotia, in collaboration with the NSLC Adopt-A-Stream, is working on the development of a standardized fish habitat assessment methodology for specific use in Nova Scotia. The methodology is intended to be used by the various groups involved in the protection, restoration, and assessment of aquatic ecosystems and will aid in the accurate assessment of fish habitat in our local rivers. This will help identify restoration needs, impacts of poor practises, and protection efforts.

The methodology will incorporate the use of Habitat Suitability Indices (HSI) to provide meaningful and accurate results from data collection in the field. Habitat variables are assessed in the field and are related to water quality, river morphology and hydrology, river banks and riparian vegetation, and benthic macroinvertebrates. The methodology will be modular and varying in the level of depth required so groups with different resources are able to effectively assess their rivers. The methodology will enhance our understanding of fish habitat and populations, lead to effective restoration and protection projects, and improve the health of our aquatic ecosystems.

Several groups that work to improve habitat for endangered fish have been awarded more than $1 million for projects in Cowlitz County. Clark County projects on the Lewis River total $925,383 and money for work in Wahkiakum County totals $361,505.

The grants announced recently by the state Recreation and Conservation Office come from federal and state funds dedicated to fish recovery. The money for the grants comes from the federal Pacific Coastal Salmon Recovery Fund and from the sale of state bonds.

The level of fish funding for most parts of the state has decreased over the past few years. The statewide total of $30 million recently awarded compares to $32 million in 2010 and $42.8 million the year before, said Susan Zemek, communications manager for the RCO.

In addition, grants for fish habitat work in Puget Sound total $13.5 million this year, compared to $33 million a year ago.

Cowlitz County

• Reshaping Abernathy Creek, $486,305. The Cowlitz Indian Tribe will use this grant to remove an abandoned roadbed on the east side of the creek that inhibits full connectivity between the creek and its floodplain, and place logjams in the creek to increase habitat. The tribe will excavate channels through the former roadbed and place logjams in the main channel, allowing the river to meander. The work is on state land.

The tribe will contribute $85,819 in donations of cash, labor and materials.

• Removing an Abernathy Creek Bridge, $204,000. Cowlitz County will use this grant to remove a bridge on an abandoned portion of Abernathy Creek Road. The bridge is 6 1/2 miles up the creek, near Brentwood Road. The bridge constrains the channel and limits the creek’s ability to meander and connect with its floodplain. The county will install logs and tree root wads in the creek and replant its banks after the bridge is removed

Cowlitz County will contribute $36,000.

• Restoring Andrews Tree Farm waterways, $177,401. The Cowlitz Conservation District will use this grant to restore portions of the Coweeman River and a tributary, Turner Creek, on the Andrews Tree Farm. The district will install logs and whole trees in the streams to slow the river, encourage gravel accumulation and create places for salmon to rest and hide from predators. The district also will plant trees along stream banks to shade and cool the water.

The conservation district will contribute $40,000 from a state grant and donations of equipment, labor and materials.

• Restoring Nesbit Tree Farm stream, $89,100. The Cowlitz Conservation District will use this grant to restore a portion of the Coweeman River on the Nesbit Tree Farm, which is about 8 miles up Rose Valley Road. The conservation district will place logs and whole trees in the river to trap sediment on exposed bedrock to improve salmon habitat and cool the water.

The conservation district will contribute $20,000 from a state grant and donations of equipment, labor and materials.

• Restoring the Coweeman River, $124,000. The Conservation District will use this grant to place logs and whole trees in the Coweeman River on the Baxter and Andrews tree farms about 6 1/2 miles up Rose Valley Road to improve habitat for salmon. The logs and trees will slow the river, encourage gravel to accumulate and create places for salmon to rest and hide from predators.

The conservation district will contribute $24,500 from a state grant and donations of equipment, labor and materials.

Clark County

• East Fork of the Lewis River, $212,753. Clark County Public Works will use the money to grade the outlets of two side channels of the river, install logs and root wads that act as juvenile fish habitat, and remove invasive plants and replant with native species. The project will expand side channel habitat by 3,500 square feet. Clark County will contribute $61,891 to the project.

• North Fork of the Lewis River, $401,730. The Cowlitz Tribe will use the money to place logs and jams into two side channels of the river, remove invasive plants along the bank, and replant the area with native trees and shrubs. The tribe will contribute $91,400 from a local grant and donation of labor and materials.

• East Fork of the Lewis River at Daybreak Park, $143,900. Fish First will enhance two side channels of the river, install wood structures in the river for habitat, and replant streambanks with native trees and shrubs at the park. Fish First will contribute $26,100 in cash, labor and materials.

• Eagle Island-North Channel Restoration Project, $167,000. Lower Columbia Fish Enhancement Group will use the money to design a project to restore optimum water flows in the north channel of Eagle Island, which is located in the North Fork of the Lewis River near Woodland. Optimizing the water flow will improve 2.2 miles of high value fish spawning and rearing habitat below Lake Merwin. Pacificorp and the state departments of Natural Resources and Fish and Wildlife are partners.

Wahkiakum County

• Grays River, $226,180. The Lower Columbia Fish Enhancement Group will install wood structures on Columbia Land Trust property in the Grays River to reduce water velocity, create habitat diversity and collect sediments against the toe of eroding stream banks. The structures will create pools, collect flood debris and stabilize the river channel. Additional structures will be placed along more than a half-mile of shoreline to protect important chum salmon habitat in nearby Crazy Johnson Creek. The enhancement group also will remove non-native plants and replant the area with native trees and shrubs.

The enhancement group and Columbia Land Trust will contribute $76,300 in donations of equipment, labor and materials.

• Elochoman River, $135,325. The Wahkiakum Conservation District will use this grant to place logs and tree root wads in the Elochoman River, to slowing the river and creating places for salmon to rest and hide from predators. The logs and root wads also help stabilize the channel by reducing erosion and protecting young trees on the riverbanks. The work will improve salmon habitat along more than a half-mile of the river and create a streamside forest on 4.5 acres.

The conservation district will contribute $39,500 from federal and local grants and donations of equipment and labor.

The culverts opened a passage to upstream habitat on three creeks that was effectively blocked by the old pipes. Buck, Hawley and Esmond creeks could start seeing runs of coho and chinook salmon and steelhead trout as a result of the fixes. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

The $1.5 million project took place over the summer and was funded with a federal stimulus grant. Road repairs also were done as part of the project.

The work took place on the U.S. Bureau of Land Management’s Eugene District. The creeks all feed into the Siuslaw River drainage. The new culverts replaced old pipes that were failing or that blocked fish passage because of their small size or erosion around the outlets.

Jennifer O’Leary, a BLM spokeswoman, said the new culverts are specially designed to aid fish. Not only are they larger in diameter, they also are oblong in shape to create a wider, more natural passage.

Also, rocks and sediment are placed in the culvert to simulate the natural creek and slow the water so it flows at the same speed as the rest of the creek.

“What this does is allow for more natural rates of flow while restoring the natural width of the stream channel,” she said. “It’s all about restoring more natural conditions out there in the watershed.”

Many older culverts aren’t big enough for the stream volume, causing water to speed up and jet through the pipe, clearing out any natural material and making it hard for fish to navigate upstream. And because of erosion on the downstream side where water exits, many older pipes now sit well above the stream level, blocking young fish from migrating downstream.

With the new culverts in place, fish will have an easier time. That means areas that had been off limits before will now be reachable.

“The habitat above these (new) culverts is healthy and intact,” said Leo Poole, fisheries biologist for the BLM’s Siuslaw Resource Area. “All we needed to do was open up the passage for fish and other aquatic species to get there.”

Work on the creeks only can be done during a summer window from July 1 to Sept. 15. To get all the culverts replaced in that relatively brief opening, the BLM worked with an agency of the Federal Highway Administration known as the Western Federal Lands Highway Division.

That agency contracted with area engineering and construction firms to design and build the culverts. The number of jobs created by the project wasn’t available this week, but O’Leary said it was at least a dozen and possibly more.

The BLM has done a number of other projects aimed at improving fish habitat in the area. Previous work added boulders and gravel to portions of the Siuslaw River, creating spawning beds, lowering water temperature and providing refuges where fish can rest.

A major step toward getting approvals to dredge Lake Gregory was achieved Dec. 21 when representatives from regional agencies visited the lake for an orientation tour.

On hand for the tour were representatives from California Department of Fish and Game, Lahontan Regional Water Quality Control Board, Lake Gregory Improvement Committee and county Regional Parks Department. A representative from the Army Corps of Engineers was scheduled to attend, but canceled at the last minute. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

“The meeting was an excellent first step in terms of our working to get Lake Gregory dredged,” said Keith Lee, county regional parks director, who was present for the tour. “The different agencies’ representatives were incredibly helpful in providing solutions.”

The group assembled in the North Shore parking lot at 1 p.m., where Phil Krause, county park planner, started the tour with a briefing on past dredging efforts. He explained how silt and debris flowing into the lake from the silt basin near the new county library building has created large sand bars in the swimming area, limiting visitor access.

Another source for the silt is storm drains, especially those near the ball field.

After the briefing, the members walked over to the silt basin to see the area, then moved on to other areas around the lake, including areas near the Leisure Shores Community Center and the ball field where silting is a major issue.

“I think we’re moving along in a good way,” Lee added. “We won’t be able to get away from doing some California Environmental Quality Act (CEQA) work, but we’re looking for ways to work together to dredge the lake and get it back to the condition that I think many in the community would like it to be in.”

Members of the Lake Gregory Improvement Committee who were on hand for the tour included Aaron Creighton, Rick Dinon (who leads the committee), Mick Hill and John Short.

“We have continually emphasized to the regulating agencies that Lake Gregory is not just a county asset, but an important asset to the Crestline and Lake Gregory community,” said Dinon. “The good news is that we’ve encountered a lot of cooperation.”

Committee member Aaron Creighton said he also was pleased with the response from the Fish and Game and Lahontan representatives who took the tour.

“We now have a vastly greater view of what needs to be done,” he said.

Creighton said that in order to get permitted by Fish and Game and Lahontan, the county has to be in compliance with CEQA.

“One of the tricky parts under CEQA is that if we remove habitat, we will have to mitigate the removal,” Creighton said. “There are two areas at Lake Gregory that need to be dredged, and the two have quite a lot of habitat.”

Part of the talk during the tour centered on creating separate habitat areas, and how it might be possible to make habitat areas protected. Other ideas included creating fish habitat areas in the deeper parts of the lake by depositing used Christmas trees weighed down by cinder blocks.

Creighton said one of the comments included that by pulling silt out of the lake, it would help improve the water quality.

“We will need an environmental impact report, and probably have to have a biological report,” he said. “We have heavy-duty problems at this lake.”
