Paradise Pointe at Smithville Lake
There are three disc golf courses at Little Platte Park on the shores of Smithville Lake. Beaver Creek with a Par of 56, Black Thorn with a 56-60 Par and Woodhenge which has a Par of 62-65. All three of the courses change up the fairways with open, treed and yes right next to the lake. The wind blowing across the lake can make your drives less predictable so I would recommend using floating or "expendable" discs on the holes beside the lake. Or just plan to go swimming (as I ended up doing) to try and recover your disc.
The traditional golf course is just on the north side of the disc golf courses. The park also features camping areas, beaches, walking and biking trails, shelters and much more. You do have to pay a $5 per vehicle daily entry fee when entering the park area.
