barriers and opportunities
We have hardly begun, and already have a long list of questions about how to "improve" the creek. If we look at Walley Creek through the eyes of DFO, our goal should be to restore its salmon-bearing qualities.
An obvious step in that direction would be to remove a large boulder that's acting as a fish barrier near the mouth of Walley Creek where it drains into the ocean. The rock is just a little too high for salmon to leap over, even with good fall flow. Describing this problem to people elicits really creative solutions. Get a crew of people together and roll it out to sea! Blast it out with dynamite! Put smaller rocks below it to create steps for the salmon to leap up! Tie a piece of rope around the rock and tie the other end to a truck and haul it out of there!
Ah, not so fast says our biologist and consultant. If we remove the barrier, what are we allowing salmon access to? Coho salmon imprint on a certain area, but they are opportunistic. They will try going up a small creek to see if it offers good spawning habitat. If the habitat is poor, they'll swim back to sea and try somewhere else. If we allow them access to Walley Creek now, we're just wasting their time unless we actually improve the spawning habitat higher up.
So for now the boulder is a low priority, while we consider our options for stream assessment. The satisfaction of removing it will have to wait.
Our group was formed when each of us independently contacted the Nanaimo & Area Land Trust wondering if any work was being done to steward Walley Creek in North Nanaimo. One of our members lives right where Walley Creek reaches the ocean in Hammond Bay; for decades she has watched and tended the stream, concerned by garbage washing downstream and the lack of care for the riparian integrity. The Executive Director of NALT, Gail Adrienne put us in contact, and we started by asking our local Fisheries and Oceans Community Advisor to help us. Biologist Dave Clough spent time with us walking the upper watershed, near Springfield Place, and the lowest part of Walley Creek, where it empties into Hammond Bay near Morningside Drive.
We came up with a long list of priorities for further research and restoration activities, including:
little stream, big problems
If you've lived in Nanaimo for a while, you'll notice that there is constant change. The desire to live in this beautiful place puts consistent development pressure on our land base. Over the last 50 years North Nanaimo has changed from the "boonies" to a sea of subdivisions. (If you want to read more about the History of Walley Creek click here.) Most urban creeks and streams have either been culverted and paved over, or treated as dumps for fill since they are less desirable areas for development. Fortunately, Walley Creek has not been paved over, but it suffers its share of degradation in areas that have not been protected as park land. Some of the factors motivating the protection of Walley Creek are - development encroaching into precious wetlands, and illegal dumping of yard waste in riparian areas. We want to protect this beautiful corridor for all the life it supports, and for the human health benefits of having access to nature.
