Not from SD but do a lot of fishing around that area. Iím in Omaha and itís a short drive for the quality of fishing. Most lakes Iíve been to around that area are just that, mostly fishing lakes. The most recreational lake Iíve seen for water sports around that part is Lake Poinsett. There are lots of lakes around that part of the country. Let me know what you like best, i may try wakeboarding around there at some point.
