I've visited Wodehouse Marsh many times over the years; it's one of my favourite birding spots nearby. With a huge marsh area, a beaver dam, and Wodehouse Creek wandering through the middle, it's very diverse habitat. You can walk out on a drier peninsula between the two sides of the wetland, and you're sure to see some interesting birds.
I've always enjoyed watching the large beaver pond; the noise from the fall of water over the dam greets you as soon as you get out of the car. This time it looked like the beavers had actively been raising the height of the dam, so I went to investigate.
You could follow the creek up through the willows and grass, avoiding the ankle-twisting logs and branches that didn't quite make it into the structure of the dam, and climb right up close. The dam has certainly increased in height, backing up a large pond of open water.
Eventually I was able to climb right up on top of the dam, and look past it. Quite a feat of engineering for a few busy rodents!
