I took these pictures a few summers ago on a camping trip at Bean Lake near Iatan, MO.
This very shallow lake used to be the Missouri River until the current cut a new channel and the river "moved" a half-mile to the west. The lake is choked up with lily pads, but we were able to go tubing and water skiing that weekend. (See the photo below).
Another fact that is really interesting to those who love history, as I do, is that the Lewis and Clark Expedition of 1804 camped along the shores of the Missouri River in this vicinity. Records indicate this area was an overnight stop, though the exact location is vague due to the changing of the river's course over the centuries.
Enjoy your weekend!
