What is Project 366? Read more here!
The water level has been dropping in the Whitemud Creek and the flow of the water has slowed down substantially from oily a week ago. It is remarkable how the level of the water and speed of the flow closely reflects the current precipitation regime. As soon as there is a break in the weather, it does not take long for the creek to adjust. On a few occasions I have tried to track the upstream meandering and branching network of creeks in Google maps but once one gets past the airport (about 30 kilometre away) there has been so many bifurcation and the creeks are so small that one is starting to loose track of them. What this exercises has revealed, however, is that the watershed of the Whitemud Creek is quite large and much of of it spans agricultural fields. This probably also means that there is likely quite a bit of fertilizer and herbicide run off ending up in the creek. In addition to this I have also come across several outfalls that flow into the creek… so, yeah…, I would pass on drinking the water or going for a bath.
