A ferry that operated from about 1882 until 1903 just east of where where Highway#10 now crosses the Souris River at Riverside.
Sheppard's Ferry was on 21-6-19. When Iscouted the area there were only a few spots where a gentle approach and low banks would alow for a ferry site. This site, just easy of the old bridge site is the most likely.
Here's another view taken near the site of the old bridge.

A Sheppard's Ferry Post Office was opened nearby in 1883 and closed in 1885. Maps show it on the south side of the river.
Sheppard's Ferry was replaced by a bridge - the remains of which can still be seen.
