Hi June, He may have been working with the Army Corps of Engineers who used snag boats on the rivers. Have you done a google search? I used the terms "snag boats" 1910 and got a lot of hits. You can look at images only to see some of them. I'm sure there is a lot of information about them. If you could find the name of the boat, you might find more about it. I hope this helps you.

In 1909-1910 my dad worked on a Snag Boat on the Missouri River by Sioux City and the Sioux River in So. Dakota . These were called Government boats. I have a picture of him in a sailor suit with a fellow I don't know. I know he was never in the Navy because in 1911 he was 18 and started on the railroad. He was not in W.W. 1. If someone might know someone who worked there at this time I wish you will write. Thanks June _____________________________________________
