During the summer of 1895, Captain Hodges, who worked under Major Jones on the improvement of the Missouri and Yellowstone Rivers, came to St. Paul as a temporary replacement. Hodges supervised completion of the Sandy Lake lock and dam and continued gage readings of water flow at St. Paul, which began in 1889. The headwaters reservoirs provided an additional foot of water for navigation between St. Paul and Lake Pepin during August, September, and October.
