Exploring Jackson Creek’s Lost Tributary: Hidden Creek

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.
