Milwaukee River Trip   4 comments

Stephen Rose and I visited the Milwaukee River yesterday afternoon. Look at that picture down there. Isn’t that a beautiful place? That could just a well be the West Fork of the Chippewa River in Vilas County. But it’s not. It’s in Milwaukee.

Stephen and I have talked frequently about what it means to have “non-invasive” non-native fish in our water system. I found out that the village of Grafton, which had a referendum on what to do with the dam in their community, voted to keep the dam in place, but to put in a fish way to allow fish passage up and down the river. The DNR, later on, determined that it would be a bad idea to allow fish to migrate upstream of Grafton because of the risk of invasive species like Asian Carp invading the upper Milwaukee River system. At some level I agree that it would be good, if Asian Carp were to make their way into the Great Lakes, for them to be prevented from invading the upper Milwaukee River. But I also think it would be a good thing for Brook Trout to be able to migrate from spawning areas in the Northern Kettle Moraine creeks all the way out to Lake Michigan and back. We’re not going to get anywhere in reintroducing native Coaster Brook Trout into the Lake Michigan Tribs if they can’t get from the lake up to the creeks at the upper reaches of watersheds like the Milwaukee River.

So, how do we all determine what’s best? How is the presence of large, non-native predatory salmonids in the Great Lakes appropriate? Salmon and Steelhead are certainly admirable creatures. Their migrations are awe-inspiring and spectacular. But how does their presence negatively affect the native Bass, Pike, Suckers, and Whitefish, not to mention Brook Trout and Lake Trout, both of which are also native?

These questions are larger than me. Many people don’t even care, or don’t even know. Maybe it doesn’t matter. Maybe we humans are programmed to reshape our world to our liking, and introducing Salmon and Steelhead into the Great Lakes is just part of our role in the world.

Anyway, a couple of boys were fishing along the bank and were slinging lures at Salmon. They didn’t know what they were doing. They weren’t having any luck. One ended up snagging one in front if its tail and was having trouble getting it to hand. I asked if I could lend a hand, and waded over to collect the fish, pull the hook out, and give it to the boy for his buddy to take a picture. He was genuinely in awe of the creature, a large, toothy fish half his height in length.

He asked if I’d caught any and I said no, I hadn’t. He wished me luck and as I left he expressed his love for the Milwaukee River. So, did that Salmon get him to fall in love with the river? It probably had a lot to do with it. And that, to me, seems like a good thing. If people care about a place because of their experiences there, it makes sense to provide them with cool things to experience in that place. It’s hard to fall in love with a polluted and fishless river. But a clean, swift moving river full of big fish will draw a lot of visitors to it. Those visitors will want to see that the river is taken care of. So maybe introducing Salmon and Steelhead is overall a positive. It’s hard for me to say. Perhaps you have some ideas? I’d love to hear what you all have to say.

Native “Coaster” Brook Trout in Milwaukee River   5 comments

I checked the Mequon-Thiensville Fishway Camera website this morning and got a big surprise. A picture of a native Coaster Brook Trout swimming upstream in the Milwaukee River.

This would not be so shocking to find in a tributary of Lake Superior, but I never imagined a Brook Trout would be swimming up the Milwaukee River. It goes to show that tearing down dams really does allow a river to support more wildlife.

If Grafton and West Bend would tear down their decrepit dams these Coasters would have a true shot at making their way up to Brook Trout spawning habitat in the Northern Kettle Moraine headwaters. Can you imagine the Milwaukee River being home to the only native anadromous salmonid? How cool would that be? Could West Bend become the Coaster Capital of the Midwest?
