When I got back from Texas, a week after John and I sprayed, looking at the lake was pretty discouraging. Earlier this week, I was driving past our lake on I35E and I could have sworn I saw the outline of the route John and I took with the canoe and Roundup. Friday, we canoed out into the lake and discovered that canoeing is possible. Today, my wife and I ventured out on the lake with a camera and took some pictures of our lake and, I hope, you can see where John and I whipped up on the lilies; and where we didn't.
The recommended 2nd round of spraying would have really cleaned out the open areas. But you can easily get around the lake and if it's far from perfect it's also far from completely jammed with lilies. The large treated center section is considerably less populated than the untreated edges. Some of the pictures show the difference pretty clearly. The path around the island is less obvious, but in the right light from the right angle, you can see where we were. On the canoe, the cleared area is the only path around the lake.
Some of my wife's pictures show how badly the lake is infected with milfoil. I have no idea how we're going to beat back this contamination, but I suspect that we need some more life in the lake to help with this; animals and fish. There was more life on the lake this afternoon than there was all summer. We spotted a dozen geese, the same number of ducks, a couple herons, and a couple of least bitterns. If we can get an early start with the herbicide next spring, maybe some of the birds and animals will stick around for the summer. The lily infestation pretty much forces the birds to look elsewhere for habitat and hunting.
