"The Tressle" bridge used to carry the old railroad that traversed the area. Now the tressle is home to some of the areas best fishing. Served as a hot spot for fisherman, and a trail for walkers and bikers, the tressle is a classic structure of the Okobojis. We spent days jumping off of the tressle doing cannonballs, preachers, flips and the like. I know in my life my friends and I have caught literally tens of thousands of crappie and blue gill off the tressle bridge.
