Kettle River Watershed Management Plan – A year in review

In anticipation of our Watershed Update on November 25, this two-part column will review some highlights from the last several months of work, and next week preview the work in the coming year.

As of the end of November, it will be one year since the Regional District of Kootenay Boundary endorsed the Kettle River Watershed Management Plan and ‘launched’ it for the benefit of the Kettle River and its communities.

The endorsement by the RDKB and the Boundary municipalities (Grand Forks, Greenwood and Midway) – as well as other organizations and government departments – signaled a significant commitment to continued local leadership in watershed management. This commitment is special because while much of the jurisdiction over water supply and resource management lies with the provincial and federal governments, it truly takes the vision and collective effort of local and regional partnerships to achieve meaningful change.

The leadership by local water suppliers and the provincial government was tested this summer during the heat wave and drought, even before the fires hit. Local government officials and water managers assembled in early August to share information on water conservation efforts and drought response, and the conversation is already having an effect. We are meeting again this week to plan for how we will work together over the next year in terms of drought response, water conservation, and information exchange.

The drought and fires of 2015 fit the expected pattern of climate change, with wetter winters, earlier spring run-off, and long, very dry summers with increased drought and fire risk. The Plan identified a suite of actions to build resilience to climate disruption in the Boundary. In our view, resilience includes both reducing greenhouse gas emissions (mitigation) and reducing climate risks to water, land and communities from flood, drought and fire through local solutions (adaptation).

To that end, the Regional District is undertaking a study to determine the feasibility of using local government carbon offsets to fund restoration of streamside (riparian) and floodplain forests. If the feasibility study has promising results, this approach would both sequester carbon in the growing trees and provide protection for shorelines and floodplains from damaging floods. We’ll know more in the coming months.

The Plan determined that riparian areas faced significant risks from various land uses and management impacts, so we knew we had to study the issue further. While there have been some efforts to increase stewardship of riparian areas in some sectors, no one has been monitoring the combined effects of land use and development including forestry, range, recreation, industry, agriculture, and urban development.

To study these impacts, I worked alongside Jenny Coleshill (Granby Wilderness Society) to develop a ‘threat assessment’ of riparian areas across the watershed, using spatial information, maps, and in-field conditions. At our Watershed Update we will share the results and point the way towards better protection, management and restoration of riparian areas and wetlands across the watershed.

Throughout the last year an informal partnership known as the ‘Boundary Habitat Stewards’ (Christina Lake Stewardship Society, Granby Wilderness Society, Boundary Invasive Species Society, Grand Forks Wildlife Club, RDKB, and BC Forest Lands and Natural Resource Operations) has been active on many restoration and habitat enhancement projects across the region. These include habitat enhancement for the endangered Speckled Dace in the Granby, Kettle and West Kettle Rivers; slope stabilization and fish habitat protection at Sion Cemetery west of Grand Forks; wetland restoration at Boothman’s Oxbow Provincial Park; and a native plant nursery and lakeshore restoration at Christina Lake.

We’ve also been building our capacity for restoration by bringing in restoration expert David Polster to teach a course on riparian restoration at Selkirk College. Residents, landowners and stewardship group members from across the Boundary participated and learned hands-on about restoration of eroding streambanks and hill slopes.

There so is much more to share about the last year than I have space for here, so come on out on Wednesday, November 25 to the MacArthur Center in Greenwood (above / behind the library) for some dessert at 6:30 and an informative evening of presentations and conversation (7:00-9:00).

Sion Cemetery Slope Stabilization Underway

Efforts to protect fish habitat and protect graves at the Sion Cemetery are well underway, thanks to the efforts of course participants and volunteers during a recent course on Soil Bioengineering.

Everyone who watches the Kettle River has seen it change its course over time. But when Pat Horkoff saw rapidly advancing erosion threaten graves at the Sion Cemetery west of Grand Forks, he called together local groups to find and implement solutions.

Since 2011, Horkoff, Chair of the Sion Cemetery Society, has noticed a disturbing trend on the slope below the site. The north bank of the Kettle River had started slipping into the river at an alarming rate. Not only graves were at risk: sediment from the eroding slope threatened to choke the valuable fish habitat in the side-channel just downstream. The problem stemmed from a log jam that shifted, directing a portion of the current against the slope and undercutting the unstable sand and gravel.

Horkoff approached me, Jenny Coleshill of the Granby Wilderness Society and Regional District Director Roly Russell to ask for help. What could we do to protect the Cemetery and the side channel?

Over the last year, we developed a plan to protect fish habitat and graves at the same time using a ‘soil bioengineering’ approach with native plants. We knew the steep, unstable slope made it a very difficult site for a typical engineering solution such as ‘rip-rap’ (angular boulders placed on the base of the slope). Furthermore, having machinery cross the river would be too risky and costly.

Instead, we investigated using woody plants such as cottonwood, willows, and red-osier dogwood to stabilize the slope. The practice is known as ‘soil bioengineering’ (not to be confused with genetic engineering and genetically modified organisms, or GMO).

These plants are special. First, they adapted to life on riverbanks and gravel bars by tolerating ‘wet feet’ – roots and stems that can be submerged for part of the growing season. They grow roots rapidly in search of nutrients and moisture, up to 1 cm per day, quickly creating a root mass that can protect the banks from further erosion much better than the fine, shallow roots of grasses.

Most importantly, if the timing is right their stems can root almost anywhere along the length, even when there is no roots. In natural floodplain environments, this allows pieces of stem broken off by floods, storms or landslides to rapidly root and colonize new environments. Bioengineering practitioners use this to their advantage by deeply planting dormant, live cuttings directly in the ground.

Modified brush layers protect dry erosion sites

When combined with other structural features such as large rocks and anchored logs, bioengineering can provide a cost-effective and beautiful solution to slope stabilization and streambank protection problems that benefits fish and wildlife habitat better than traditional engineering solutions.

To build our skills and get the project going, we invited bioengineering expert David Polster to teach a course at Selkirk College (held September 17 and 18). Thirteen students from across the region and beyond learned the theory and practice of soil bioengineering and had a full day of hands-on experience installing the design at the Sion slope. We continue to work with volunteers and a local silviculture crew to complete the project in the coming weeks.

This project has been made possible by a number of dedicated volunteers from across the community, the participants in the course, and by the generous financial contributions of RDKB Director Roly Russell, the Sion Cemetery Society and the Lapsha Ladies at the USCC. Please contact me if you would like to be involved.

Presentation: Natural Processes for the Restoration of Drastically Disturbed Sites

Natural processes have been “restoring” natural disturbances (landslides, volcanic eruptions, glaciation, etc.) forever. Mr. Polster will talk about how we can use these same processes to help the land heal and restore sites such as mines and industrial developments that we disturb. Join us for an informative presentation and informal social gathering 7:00-8:30, Wednesday Sept. 16, Upstairs @ Station Pub (7654 Donaldson Dr, Grand Forks) – RSVP to plan@kettleriver.ca / 250-442-4111.
