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.

Oh that is horrible. I would suggest taking to City Council. Election coming up all candidates, especially in that ward should be aware I would think.

Please contact Fisheries and Oceans Canada. Waterways are a federal issue. Where I live near Millbrook, a subdivision was to go in, but there was a problem with a well spewing silt that got onto a strea and F and O were on the scene for quite some time!

This happened last year too, after some heaven rains the silt barrier gave way. They repaired it with a second row of silt barrier, but it has given way also.
