"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.

Emerald Hills Golf Course is one of the premier golf courses in the Iowa Great Lakes. Golfers throughout Okoboji will tell you that compared to the rest of the golf courses around, Emerald Hills is probably the most challenging. When I grew up as a kid, we lived just a half block from the back side of the course. We would sneak on with a couple short little clubs and balls we found walking the course and sometimes spent more time being chased by the sprinklers than trying to hit golf balls. Emerald Hills was owned by Gordy and Bette Benit many years ago and they can be credited with growing this course into the masterpiece it has become. Later purchased by Randy Rohlfsen and a few others, Emerald has flourished as one of the best courses around. If memory serves me right, Randy has been there since the early 1990's and has always had a strong conviction to help young golfers. He has taught and coached numerous high school teams, and they also put on a 5 day junior camp every year which has been a tremendous hit. I grew up on this course and can honestly say, you better be hitting the ball straight!

Referred to locally as the lake turning over the thermocline is a feature of lakes with deep water. The water on the top of the lake changes temperature much more variably during the year. On West Lake, it can reach as much as 75 degrees in July while the water below, greater than 35 or 40 feet deep is relatively stable around 45 degrees. In the fall and early winter, the top strata of the lake will cool to below 45 degrees, and then because it becomes denser, it will "sink" below the lower strata, thus, displacing it and making the lake "turn-over". In the deepest part of West Lake (near the 136ft mark), no light is availble, and hence little life is known whether fish or plant. Typically questions are raised as to why the surface water gets dirty for a short period of time in the fall, this this is the standard answer.
