Jackson Creek Pollution Update

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.

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. P_20181009_182132

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.

See How The Lilly Lake Subdivision is Impacting our Waterways

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.

The Environment, Jackson Park, Springtime, and Elections

With the upcoming provincial election possibly having a dramatic impact on the jewel in our city that is Jackson Park, I decided to take a stroll along the creek to explore the lush green valley that has recently sprung to life. The polls seem to suggest that the Progressive Conservatives will be the ones to lead the province for the next 4 years. Thus far they have not indicated in any capacity that the Natural Environment is of concern or a priority. Tomorrow, make the effort to go to the polls and cast your ballot with the future of Ontario and Peterborough’s natural environment in your mind and in your hearts. In the meantime, enjoy the eye candy that is Jackson Park in the spring!

Night of the Salamanders (And Newt)

This past week the Peterborough Field Naturalists and the Kawartha Land Trust hosted the 4th annual salamander night at the Ingelton Wells property. Despite the rain it was incredibly well attended. By the end of the night we catalogued 3 different species of salamanders on the property and a couple more on the way home! If you’re interested in salamanders and other excellent field trips in the Kawarthas and beyond, definitely consider becoming a member of the Peterborough Field Naturalists!

3D Printing Peterborough Watersheds

Within the sphere of 3D printing there are a plethora of examples of how to print topographic maps. Much of this interest comes from the reproduction of topographies from popular video games or modeling significant landscape features such as mountains or canyons. The standard format has been to display these models using arbitrary or aesthetically pleasing boundaries, often a square or a circle (or even puzzle pieces)

One of the primary motivators for my acquisition of a 3D printer was the ability to reproduce landscapes with the natural watershed boundaries that already exist. This turned out to be a much more daunting task than I had initially anticipated, however I think the results were well worth it! Now that I have started to refine my techniques, I hope to be able to reproduce interesting watershed topographies for all of Peterborough and beyond!

The Mississippi River model as seen from the air (US Army Corps of Engineers, 2006)

Watershed models have a long history in the management of water resources. The US Army Corps of Engineers produced a gigantic scale model of the Mississippi basin to assist in flood prediction and management long before computers were able to complete the task. Even today, physical models are able to produce results that computers are unable reliably recreate. Perhaps with the refinement of 3D printing technologies we will once again see the models that assisted our resource planning in the past reemerge as a common element of our watershed planning future.

Stewards Notes Now Airing Live

Last week I had the opportunity to show Hayden Watters from CBC the natural heritage system map of Peterborough. I had never intended the popularity of the map to take off in the way it did, I simply needed a visual aide. Follow us around the city as we explore the different “transit stops” along the different transit lines. If you’re interested in the interview or want to learn more, head on over to CBC Ontario Morning and check it out. The interview starts at 12:22.

Peterborough’s Natural Heritage System Metro

One of the obvious metaphors for a natural heritage system is a road or subway network for species that aren’t humans. Just as you require pathways to to work each morning, species need a pathway to move from their homes to their feeding grounds, water, and breeding areas. As a fun little project I decided to create a fictional metro system for all of our feathered, furry and slippery friends in the city. Each of the metro lines correspond with a real corridor that may be used by foxes, birds, snakes, and others to move between the core natural areas in our city. When we discuss the protection of our nature areas, we must not forget the metro system that connects these important natural spaces.

Building Turtle Habitats in Jack’s Marsh

In Ontario and Canada there is a plethora of funding opportunities for protecting species at risk. Grants from the Federal, Provinical governments and NGOs assist organizations in protecting species at risk across a wide range of habitat types. Turtles are among some of the most threatened species in the province, and the Northumberland Land Trust is working to protect them. Unfortunately we don’t know what turtle species are out there on our properties.
