Jebbs Creek Wetland Embayment Creation Project
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.
Project Description
Project implementation was carried out by the RVCA and partners. A variety of techniques/applications were carried out, including:
- The removal of fill from the existing shoreline to create a series of small embayment’s with a variety of slope conditions
- In-water planting of aquatic sedges and grasses known to be favorable for northern pike spawning
- Installation of wood structure to further enhance nursery habitat
- Re-vegetation of the riparian area by planting native trees, shrubs and wetland vegetation
- Maintain the pathway system adjacent to the embayment feature to continue access for recreational use
- Deposit the excess fill in specified areas in the adjacent field outside of the regulatory area and seed these areas with a pollinator seed mix to support pollinator habitat
- The installation of an interpretive sign along the adjacent existing pathway, with partner logos, describing the project benefits from a watershed management perspective
Project Timeline
- (2015-2018) background data collection to inform the detailed design process
- December/January 2017/18 Refine and further develop the wetland embayment proposal
- February/March/April 2018 prepare Detailed Design (contour plan, cross section plan, landscape plan, structures plan)
- April 2018 site visit with RVCA/MNRF staff

Information:
April 11, 2018 – A weather system out of the mid-west U.S. has the potential to bring several forms of precipitation in significant amounts in to eastern Canada over the next week.
Snow, rain and freezing rain may fall beginning tonight with showers or flurries. Tomorrow, rain is forecast to fall through the afternoon. Rain is expected to begin again late on Friday morning and continue into Saturday, changing to snow in the early morning finishing with as much as 20 centimetres. Rain is presently expected to resume on Sunday and continue into Monday.
If the full amount of forecast precipitation falls, there is the potential for minor flooding to occur in the Long Reach of the Rideau near Kemptville. The lower lying communities in that area may have access issues.
Water levels throughout the watershed are below average for the time of year so there is capacity to accommodate some of the runoff with little impact. Cooler than normal temperatures are forecast which could mean that the runoff process will be slowed to an extent with freezing temperatures overnight. Temperatures closer to spring-like are not expected until the end of next week.
This weather system has the potential to develop into a more significant event over the next five days. RVCA staff will continue to monitor and further statements will be issued if conditions warrant.
Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Streambanks are slippery and any remaining ice cover on streams, ponds and lakes will be hazardous. Parents are advised to keep their children and pets away from all watercourses as levels fluctuate with the spring weather.

Flows in Rideau Valley to Fluctuate from Latest Weather
April 3, 2018 – Rain in the order of 20 millimetres is forecast for today and into the night that will cause water levels throughout the Rideau valley to increase beyond levels reached after rain on Saturday.
How much levels increase will be limited by dropping temperatures and the changeover from rain to freezing rain or snow overnight and tomorrow. Peak flows from this weather are still expected to be less than average for the spring freshet. These may not be the actual freshet maximum flows.
The Long Reach of the Rideau River, between Manotick and Kemptville, could have levels over the banks as a result of the rain but access is not expected to become a problem in the small river side communities such as Hilly Lane and Cedar Beach.
Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which have been weakened as a result of the warming conditions.
RVCA will continue to monitor conditions and will issue further statements when or if there is an indication that the situation can be expected to change significantly.

Below Average Spring Freshet Expected
March 29, 2018 – Barring a rain event not presently in weather forecasts, it is appearing that the spring freshet of 2018 in the Rideau valley may have already occurred on March 2 as a result of the above normal temperatures in the latter half of February that removed all of the snow.
The snow that fell after the early March thaw, has gradually declined over the month with several sunny days and above freezing daily temperatures. With little snow and minor rainfall forecast, there is not expected to be enough runoff to cause significant increases in water levels in the Rideau valley. A flow in the order of 115 +/- cubic metres per second (cms) is possible at the monitoring station Rideau River at Ottawa if the weather that is forecast for the next four days arrives. That would be less than 50% of the long-term average spring flow.
Such a flow would cause flooding of only the lowest lying shoreline in the watershed but no residential flooding. Still, waterfront residents are advised to secure any of their possessions that could float away and ensure that sump pumps are operating properly.
Colder temperatures and snow are forecast for next week which will prolong the passing of the freshet but there is nothing indicated that would raise levels significantly.
