We decided to depart from the Oahe Marina just below the dam and end at Griffin Park in Pierre. I met them at Griffin Park, where we loaded my boat and gear into their van and trailer. We left my pickup and Cory's sister's (Dee's) pickup at Griffin Park and drove up to Oahe Marina.
We took a leisurely pace to enjoy the day on our way downstream. The high temp was in the mid 90s and the wind was from the southeast in the mid teens with 20 mph gusts, relatively calm for my trips. We made a few stops at sandbars along the way and noticed many buffalo/bison bones and teeth in the water just downstream of the stilling basin. When we reached the causeway boat ramp, we helped Cory's wife, Janey, and his sons, Sam and Aiden, over the causeway as a shorter option to our trip. Cory, Dee, and I continued on around the La Framboise island and back up to Griffin Park. Our total mileage was 11.3 miles.
