Fort Wayne, IN: Canal Feeder Dam and Robison Amusement Park, 1896-1919 posted February 5, 2020 on Towns and Nature blog included a September 2020 Facebook post that stated: Dam was in middle of “S” curve (see an arial view) on St Joe River by former site of Swift-Goshorn mill at Paradise Lagoon, just downstream from feeder canal (Summit Point). The earthen dikes are on both sides of the river, if you know where to look. This area is undeveloped floodplain, just east of Northpointe Woods clubhouse. I believe some of that is now private property, but it used to belong to City of Ft Wayne, before that it was the old Kroemer farm. I used to go back there in the seventies. Interesting thing is that area was meant to be the originally proposed site of the Fort’s backup water supply. They had planned to dam the river again in the twenties/thirties, but instead opted for the Cedarville Reservoir further upstream.
