Black Rapids Wetland Restoration Project

Super User

The Rideau Valley Conservation Authority in collaboration with NCC and the Great Lakes Guardian Community Fund have designed and enlarged the Black Creek wetland located in Ottawa’s Greenbelt. This enhanced wetland improves water quality, increases biodiversity and provides important wetland habitat in the headwaters of Black Rapids Creek.

The wetland has doubled in size from 3,444 square metres to almost 7,000 square metres. A tributary that had previously bypassed the wetland now flows into it providing a larger aquatic feature that supports amphibian breeding, fish habitat, bird foraging, and acts as a water supply for wildlife. The wetland now boasts a variety of side slopes, woody debris (i.e. root wads, basking logs and sweeper trees) and re-planting of native trees, shrubs and wetland vegetation. The project was completed in September 2016.

Staff returned to monitor the wetland in 2017 and 2019, and will return again in 2021.

IMG 7416Township of Rideau Lakes drainage manager Dan Chant joined RVCA intern Caitlin Sommer in Portland this July to paint yellow fish on several storm drains. These fish will remind residents that stormwater goes directly to the lake.The Township of Rideau Lakes has generously funded a pilot partnership with Big Rideau Lake Association, Cataraqui Region Conservation Authority and Rideau Valley Conservation Authority to work co-operatively on a sustainable drainage pilot project in the village of Portland and the surrounding rural catchment area.

As climate change contributes to more frequent and extreme rain events, excess nutrients, sediments, harmful chemicals and pollutants are increasingly washed into Big Rideau Lake through our storm drainage systems. This contributes to increased aquatic weed growth, more toxic algae blooms and an overall decline in lake health and enjoyment. 

In summer 2022, staff from RVCA as well as volunteers from the Big Rideau Lake Association conducted a sampling and monitoring program, targeting an urban drain in the village as well as a rural drain (non-agricultural) outside the village. Research was conducted to find and recommend sustainable drainage practices that are best suited to protect water quality and lake health.

The Jebbs Creek Wetland Embayment Creation Project converted a small area of existing meadow habitat in the Rideau Valley Conservation Authority’s Perth Wildlife Reserve Conservation Area to a series of small riverine wetland embayments along the shoreline of Jebbs Creek within Tay Valley Township in Eastern Ontario.

Jebbs Creek is a tributary in the Tay River watershed, which supports a warm/cool water fishery. The purpose of the Jebbs Creek Wetland Embayment Creation Project was to create 1,600 m² of new spawning, nursery, rearing, and feeding habitat for the 20 species of fish that reside in Jebbs Creek.

The Kemptville District of the Ministry of Natural Resources and Forests manages the Tay River watershed for an extremely diverse fishery which includes northern pike (Esox Lucius), smallmouth bass (Micropterus dolomieu), largemouth bass (Micropterus salmoides) and walleye (Sander vitreus). 

Northern pike is a local sport fish, well known for its large size and predatory nature. Despite its reputation as a top predator, northern pike are particularly sensitive during spawning and are often subject to high egg mortality; therefore, it is crucial to ensure that suitable spawning habitat exists to support this species. Through a multi-tier approach, the goal was to create and maintain a suitable spawning and nursery site for northern pike along Jebbs Creek, while helping to improve shoreline stability, riparian habitat and water quality. The feature also provides a small riverine wetland embayment along Jebbs Creek which will provide important habitat for breeding birds, amphibians, turtles nesting habitat with a goal to increase overall biodiversity.

2018 Construction highlights: 

  • 5 days of construction 
  • 1600 m² of fish habitat created
  • 5.5 kg of shoreline and wetland seed mixes were installed around the wetland feature
  • 5.0 kg of meadow seed mix installed in the fill deposition area for pollinator habitat
  • 15 volunteers participated in the planting day for a total of 75 volunteer hours
  • 125 native shrubs and trees planted around the new wetland feature

Post Construction Phase monitoring is scheduled for the spring/summer in 2019, 2020, 2022 and 2024.

Thank you to our Otty Lake Association volunteers!

Project Objectives

  • Enhance fish habitat by creating new spawning, nursery, rearing and feeding habitat for the fish community of Jebbs Creek (target species northern pike)
  • Improve food supply for aquatic and terrestrial species through increasing overhanging vegetation along the shoreline.
  • Improving the function of adjacent wetland habitats for aquatic species
  • Create a quiet backwater area adjacent to the main current of Jebbs Creek.
  • Provide winter and summer refuge areas for fish.
  • Protect water quality and enhance wildlife habitat by establishing a naturalized buffer with native species of trees and shrubs
  • Altering elevations to create conditions more suitable for more diverse submergent and emergent aquatic vegetation
  •  Enhance recreational and educational opportunities at the site by installing educational signage
  • Engage and educate community members by involving volunteers in the process and providing a demonstration site that shows a variety of cost-effective methods to protect and enhance shorelines and wildlife habitats.
  • Partnership opportunities with various groups and the Conservation Authority.

Walleye spawn in the spring for one to two weeks, depending on water temperatures, and return to the same spawning site each year which means they have high site fidelity to their spawning areas.  This project consisted of placing round river stone on the bed of Scanlan Creek to restore an impaired walleye spawning bed. This work will further enhance the productivity of the walleye that spawn in Scanlan Creek and return to Wolfe Lake.  By restoring this spawning bed site to a functional riffle habitat we will improve the recruitment success of spawning walleye from Wolfe Lake.

Construction Phase

Two locations measuring five metres by 10 metres were determined to be in need of augmentation with appropriately-sized river stone. Staff and volunteers installed 100 tonnes of six-inch round river stone for walleye spawning on the bed of Scanlan Creek in the fall of 2019, when water levels were lower.

What are the anticipated outcomes?

  1. Create a greater awareness about the threats to the local walleye population and how simple costs effective measures can improve spawning success and recruitment.
  2. Engage with volunteers on Wolfe Lake and in the Westport area, building enthusiasm and environmental awareness while reinforcing a strong sense of community, particularly involving youth in the hands-on element of the project, providing them a valuable learning experience and opportunity to positively impact the world around them.
  3. Educate lake residents on how habitat enhancement efforts can improve the local walleye fishery on the lake.
  4. Promote the goodwill and partnerships formed through the enhancement project.


In order to implement this project a partnership was formed between the Wolfe Lake Association (WLA), the Westport Area Outdoor Association (WAOA), the Rideau Valley Conservation Authority (RVCA), Rideau Valley Conservation Foundation (RVCF), Camp IAWAH (Youth camp located on Wolfe Lake) and TD Friends of the Environment.

Stillwater Creek Slope Stabilization Project

RVCA was contracted by the City of Ottawa to design and implement remediation of an eroded bank of Stillwater Creek adjacent to Nautica Private and Carling Avenue and into the Ottawa River. Erosion of the slope is being caused by fluctuating flow and velocity in the creek and this project will help prevent potential slope failure.

Erosion 1 copy   Erosion 2
East Bank Erosion    East Bank Erosion 

The headwaters of Stillwater Creek begin in the National Capital Commission’s Stoney Swamp. Stoney Swamp is almost 2000 hectares in size, and is a mix of woodland, wetland and regenerating fields. From Stoney Swamp, Stillwater Creek runs through a heavily channelized and impacted area adjacent to Robertson Road. The creek turns into its natural morphology downstream of Robertson Road until the Highway 417 crossing. It then becomes channelized again, as it runs through Wesley Clover Park on Corkstown Road. The creek flows through another large wetland before Moodie Drive crossing, and from there runs parallel between Highway 417 and Corkstown Road until it turns north flowing through residential neighborhoods before emptying into the Ottawa River between the Nepean Sailing Club and Andrew Haydon Park.

The first phase to be completed is on the west bank of the creek in the treed area. The highlighted blue area is the East bank portion of the work to be completed as the second phase.

Map of the Work Area

Further erosion of the bank of Stillwater Creek at Nautica Private could be detrimental to the properties on Nautica Private and to the safety of the residents. 

Rock Toe Berm Construction

RVCA looked into multiple alternatives for the slope stabilization of the banks of Stillwater Creek. RVCA decided on the construction of a rock toe berm to stabilize the east bank of the creek. Once the design was complete, RVCA had it checked by a third-party local geotechnical engineering firm.

The rock toe berm has been designed to make a “key” at the base of the slope to be filled with large “rock protection” sized stones. The slope will then be backfilled at a 1.5:1 (h:v) slope and the large stones will extend above the creeks assumed 100-year flood elevation. The work is expected to protect the properties on Nautica Private from further property damage due to erosion.

Timing

The project took place from approximately December 22019 – February 28, 2020.

The Rideau Valley Conservation Authority in partnership with the Otty Lake Association collaborated to enhance fish habitat in Otty Lake — specifically spawning, nursery and feeding habitat for smallmouth and largemouth.

What was done?

Phase 1 (2013)

  • Installed 75 gravel spawning beds a using round river wash stone
  • Deposited wood branches and small trees anchored in cement as well as brush bundles — this wooded debris created habitat for many food sources such as crayfish and aquatic insects as well as places where fish can rest, find shelter and feed

Phase 2 (2014)

  • Installed 83 spawning beds and sank 185 wooden clusters as shelter and feeding habitat
  • Placed 58 large rocks (cornerstones) various nests providing additional cover for dedicated smallmouth bass fathers as they brood their young

Phase 3 (2015)

  • 49 spawning beds, nine brush piles were placed in shallow weedy bays to provide more shelter and feeding habitat
  • 75 cornerstone were placed at various nests which provides cover and shelter for the guarding male and fry

Through all three phases 228 bass nests were installed, 133 cornerstones added, 335 trees/branches and nine brush bundles placed in shallow areas. A total of 840 volunteer hours were accrued. In addition, 20 wood duck nesting boxes were installed.

Monitoring:

RVCA staff and volunteers monitored the success of the project with site visits in spring and summer. This entailed counting active nests, making observations on the integrity of the gravel and observing the wood structures using an underwater camera.

The Results:
successful/confirmed spawning on nests

2014 — 41%
2015 — 43%
2016 — 55%
2017 — 36%
2018 — 56%
2019 — 58.5%

The Rideau Valley Conservation Authority (RVCA) partnered with the National Capital Commission (NCC) to design and construct a small wetland adjacent to the Ottawa River. This new wetland is located close to Remic Rapids along the Sir John A. Macdonald Parkway. The feature is 0.15 hectares and consists of a shallow basin that is a water supply for wildlife as well as amphibian breeding and bird foraging area. Volunteers and NGO community groups provided clean up and planting assistance. The wetland provides a unique and highly visible habitat feature along the National Capital Commission Ottawa River Pathway.

Benefits of the Project

  • Altered elevations creates areas for more diverse aquatic and terrestrial plant life
  • Provides new and enhanced habitat for wetland wildlife
  • Provides quiet area for water fowl and shorebird nesting, rearing and feeding
  • Installed woody structures creates more diverse habitat
  • Installed sand and pea stone creates turtle nesting and basking areas
  • Common buckthorn (invasive species) removal allowed for more native plant growth

Hogs Back to Kars & Kars to Burritts Rapids

The Rideau Valley Conservation Authority (RVCA) has completed two hazard mapping studies for the Rideau River: Hogs Back to Kars and Kars to Burritts Rapids. These studies update existing mapping in some areas and new mapping in others.

These maps are typically known as “floodplain mapping” and they show areas that are prone to natural hazards such as flooding, erosion and natural environment features such as wetlands. Both Rideau River studies look at identifying two main types of hazards along these stretches of the watercourse: flooding and slope stability. 

When completed, the mapping will be used by the City of Ottawa and the Municipality of North Grenville when updating their Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. RVCA will also use the mapping to guide the review of development applications submitted under the Province’s Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.

Members of the public are encouraged to attend our open house and/or provide comments on the mapping below. Conservation Authority staff welcome historical records of past flood events, news clippings, photographs and even anecdotal stories to help confirm the reasonableness of calculations and resulting hazard mapping. For those unable to attend the open house, comments can be sent to Ferdous Ahmed, RVCA Senior Water Resources Engineer at .

These mapping studies are being completed as part of the City of Ottawa Hazard Mapping Project.

These studies are being done through a collaboration — known as the City of Ottawa Hazard Mapping Project — involving the City of Ottawa and the Mississippi Valley, Rideau Valley and South Nation Conservation Authorities. The City recognized a need to update its zoning schedules based on up-to-date flood risk mapping and has provided contributions enabling the Conservation Authorities to move ahead with these studies sooner than would otherwise be possible. The RVCA is currently working on several studies in the Ottawa area.
