On this rainy Monday I decided to spend some time “rummaging” through my digital photo collections. Interspersed among the plethora of photographs was a reasonable sized video collection of creeks and streams around Peterborough. With windows movie maker in hand, I decided to put together a relaxing 2 minute cut of the clips that I found. We could all use some relaxation these days, don’t you think?

If you walk along Jackson Creek in the coming days, you may see a unique little insect crawling along the surface of the snow. These are winter stoneflies. This time of year, the emerge from the bottom of creeks and rivers where they have lived the first year of their life. Although they have wings, they choose instead to crawl along the surface of the ground in search of a mate.
To keep from freezing while under the water, they stay in pockets of air under the ice that only reach about 0°C and promote supercooling in their cellular structure. This allows their bodies to reach temperatures several degrees colder than 0°C before freezing. They also produce some anti-freeze compounds when they are adults and ready to emerge.
In the coming days and weeks, be sure to check out this cool creature along the banks of Jackson Creek.
This time last year, wildflowers were in full bloom across the Kawarthas. This spring has been rather slow to start the bloom. I wanted to be prepared for the eventual blooms of wildflowers throughout the city, so I started with the closest park. Jackson Park isn’t exactly prime wildflower habitat, I suspect that nearly a century of heavy human use has probably had an impact on their diversity in the area. Nevertheless I was able to find some early signs that Trout Lillies and Marsh Marigolds will be blooming soon in Jackson Park!
The willow is starting to put out buds and the poplars and birches have catkins weighing down their branches. I also noticed that two of the mighty white pines adjacent to the pond are in rough shape, and may in fact be dead… A sad day for sure. Also plenty of signs of woodpeckers in the park. Noticed a beautiful Pilliated Woodpecker high up on a dead tree.
Today Steward’s Notes is pleased to announce a successful bid to replace the Simcoe St. parking garage with a natural outdoor park! This will provide an excellent opportunity to bring daylight back to Jackson Creek and create outdoor space for the downtown community! After working with municipal counterparts it was agreed that the parking garage was underutilized and should be replaced with a showcase of Peterborough’s Natural heritage and beauty! Once again daylight will shine on Jackson Creek for the first time since the 1960s. The multi-million dollar contract will enable the total removal of the parking garage and subsequent replacement with outdoor greenspace. The bus terminal will be relocated to the King St. Parking Garage once construction begins. The benefits of this park promise to be immesurable and include:
About two years ago I was having a conversation with a friend and he asked me about a small little creek that ran through his backyard at the time. Knowing where he lived, I knew it was a tributary of Jackson Creek, but nothing more.
I’ve passed by this creek countless times, small creeks have always fascinated me but I’ve never had the opportunity to explore this one in particular. Small creeks and streams are some of our most fragile yet least understood aquatic ecosystems, yet they make up a large part of our watersheds. As Peterborough was built, countless small creeks were filled in, many people have wet basements because of it, but this small creek remains.
Having recently acquired a copy of a historical atlas of Peterborough, I wanted to understand how some of these environmental features of early Peterborough might still be visible today. This little creek seemed like an excellent starting point.
Blessed with a sunny day and high spirits, I decided to go out exploring….
At the base of Hidden Creek you can see where it spills out into Jackson Creek. The culvert has clearly been installed for several decades. Its nearly invisible this time of year, with Jackson Creek’s levels so high. Its not clear if any water is actually spilling out from underneath the bicycle pathway.
One block north on McDonnel St. it is possible to see where the embankments have been stabilized to make room for more construction. The heavy concrete construction seems to indicate that this creek may have been a bit of an engineering problem at the time. I suspect that before sewer system upgrades this little tributary received a lot of rainwater runoff from the city to the north. Continuing several blocks to the north, you can see how this little creek has been tucked away between lotlines, hidden from view. Neighbors have attached their downspouts to the channel to quickly convey rainwater away. From street level there are sometimes ornate iron bars that prevent passers by from falling into the channel. As you approach the head of the stream the water is not frozen, perhaps there is a hidden spring feeding this creek from below the city.
Finally upon reaching Parkhill road, is the most natural portion of the creek. Its “headwaters” you might say. From underneath the roadway Hidden Creek spills forth into a small grassy space. Apparently this land is municipal property! A great opportunity for a community group to install a pollinator garden or do a small tree planting along the creek’s edge!
Peterborough is full of long forgotten creeks, and this is but one of them. Do you know anything about this tiny Hidden Creek? Do you know of other little environmental hotspots in the city? Perhaps as the summer progresses I will try to discover more of these forgotten places.
This spring so far has not given us much in the way of precipitation, but that’s not to say that we can’t see our surrounding environment hard at work. In Peterborough we have a long history of flooding in our downtown and surrounding neighborhoods. Looking at old maps of Peterborough, it is easy to see why this is the case. When the area was first settled 200 years ago, Jackson Creek meandered through a wetland located where the downtown currently resides. The river still carries memories with it, when the downtown flooded in 2004 the path of the stream passed through buildings and shops in much the same way as it did in times gone by.
Every spring with the influx of water caused by spring melting, we can witness how Jackson Park keeps water on the landscape and out of basements downtown. When the ice first melted this spring, giant dams of ice formed along the creek, water spilled over the banks of the river, and flowed through the trees and brambles that line the side of the creek. The water was slowly released back into the stream to travel towards the Otonabee. It made quite the sight to behold, however the implications are clear:
“Water is held in Jackson Park and the Lilly Lake Wetland instead of the basements of downtown homes and businesses”
(ed. The Previous) City council has had this explained to them on countless occasions, however it is clear they are not listening, or don’t care. Actions that reduce the ability of the wetland and park to properly function are at the direct expense of Peterborough business and home owners. The next time Peterborough proposes filling in wetlands or clearing forests, remember that you are the one who may be paying the bill.
With a new city council that may be willing to keep a closer eye on the natural assets of our community many hope that our natural assets may be accounted for in the same ways that our fire hydrants, sewers and hydro poles are. Just the same way that these assets depreciate, if we do not care for our natural spaces, they too will lose value over time. There are many groups and cities in Canada, such as the municipal natural assets initiative that are working to find ways to account for the value that spaces such as Jackson Park provides. Hopefully in the coming years we can find a way to include the value that natural features bring to our life in Peterborough!
Today I took a stroll up to the Lilly Lake Subdivision to discover what had come of last week’s events. I knew that on Friday there had been activity on site, but I didn’t feel like popping my head into an active construction site, one that my actions may have precipitated. It seems that the construction company has fixed the giant hole in their sediment fencing by adding several more layers. Sections of the fence now are 4 layers thick. In addition, a wall of boulders was constructed at the outlet of a giant erosion scar. It will be interesting to see if even they can hold the water back. (more…)
Today I received word from City Councillor Henry Clarke stating that a sediment fence had failed on the site of the Lilly Lake Subdivision and that as he wrote the email they were working to repair it. With another rain storm headed our way I decided to go up and have a look at the work as it was being completed. I walked up the Jackson Creek Trail through the park. As I walked along the trail I noticed that giant sheets of mud had been left next to the trail from all of the water that had flowed through the site.
Sheets of mud deposited along Jackson Creek Trail
I ascended the slope out of the river valley to notice the first spot where the erosion fencing had failed. Across the huge swath of property there was nothing but bare soil. No erosion control had been implemented on site.
Failed silt fencing.
No erosion control on site
I continued further along the southern boundary of the property, the mud was thick and deep, more than once I stumbled and fell. Just as I was about to leave, I noticed where a huge swath of grass leading into the river valley had been washed out by water. I approached and discovered one of the largest erosion scars that I have ever seen.
The silt fencing had totally failed and you could see that possibly hundreds of tonnes of sediment had escaped the property and flowed down the valley into Jackson Creek.
I’m disappointed that this hasn’t been dealt with. Fish are currently spawning and this could lead to a massive kill of the eggs this year. In the mud I didn’t see any evidence that any humans had actually investigated since the last storm. I’ll be taking more action in the coming days and I’ll be sure to keep you posted.
This past week my partner alerted me to the fact that things in Jackson Creek looked a little off. “Like chocolate milk” is how she described it. I’ve seen rivers that looked like chocolate milk before, but never Jackson Creek. I decided to go have a look to see what was causing the phenomenon. First I went down to the creek near the entrance into Jackson Park. Indeed the water was murky with silt and mud.
Murky water like this is bad for fish and other aquatic organisms. It can suffocate fish, decrease light reaching into the water to allow plants to grow and can mean increased nutrients will lead to algae blooms and decreased oxygen concentrations.
After discovering the milky water that had found its way into creek I wanted to see what the water looked like upstream of any housing developments. I drove outside of town to see what the water looked like where the river crosses under Ackinson Road.
Sure enough the water was clear and crisp. Some tannins were in the water that gave the water a “tea like” appearance. This is a natural phenomenon and no immediate cause for concern. It was obvious that there was something along the banks of Jackson Creek that was causing the pollution in the area.
Flowing into a small tributary along the North side of the housing development on Lilly Lake road was one of the most egregious cases of poor sediment control. Along the slopes of the new construction, huge gullies of sediment had been carved out of the embankments and sediment was pouring into a failed stormwater pond to be deposited in Jackson Creek.
I’m not sure what how to fix this situation, city council is consistently unwilling to take action on these issues, Peterborough is home to several failed stormwater ponds. And it seems like the problem is not getting better any time soon. Perhaps a new city council will be willing to make the changes required to ensure the continued health and wellbeing of our waterways, and ultimately our community as a whole.
