Beaver Protocol Pilot Project No.1 - Hyde Park Stormwater Pond No. 1

The Hyde Park Stormwater Pond No. 1 is currently the home of a family of beavers. The beaver activity has led to a blockage of the stormwater pond’s outlet impacting the functioning of the stormwater pond. Upper Thames Conservation Authority staff will be installing a flow device that will allow for the beaver family to remain in the pond and allow the stormwater pond to perform as designed.  Following this work, seeding of the exposed soil and beaver food tree plantings will be undertaken. Photos will be included below as the project proceeds.

Beaver Flow Device Operational Chronology


May 30, 2015 - Beaver Flow Device shortly after installation.

May 31, 2015 - A small rainstorm has raised the water level in the pond.
The beaver flow device is functioning well.

June 1, 2015 - The day after the small May 31st storm. The flow device
worked well and the pond level has come back down to its normal level.

June 3, 2015 - A day after another small rainstorm. You can see the beavers

have done some work to block the sides of the cage around the outlet drain.

The device is functioning well. In the foreground you can see the seeding

undertaken to ensure invasive species do not take hold. The seed mix

includes rye grass and mix of native plant species.

June 12, 2015 - The beavers have packed more material around the flow
device cage. The flow device continues to work well. An unexpected benefit
of the beavers work has been that floatables (empty bottles,
dead vegetation, styrofoam) are being prevented from clogging the outlet
due to the surrounding wall of mud.

June 23, 2015 (Morning) - During the night of June 23, 2015 the City received
a massive storm event. This photo was taken in the morning. The flow
device is completely under the water. This was expected due to the large
magnitude of the storm.

June 23, 2015 (Afternoon) - This photo was taken at 7:00 p.m. following the
massive storm. The flow device performed well following the storm and
allowed the pond to function as it was designed.

July 17, 2015 - The seeding along the edge of the pond has become well
established. The flow device is working well.

August 24, 2015 - Positive aquatic plants are starting to re-establish. Beaver
device continues to work as anticipated.
