Johnston is unusually well-set for the outdoors: more than 45 miles of city trails, the paved Neal Smith Trail running along the west side toward Saylorville, and quick access to Big Creek State Park and the High Trestle Trail just north. Details in our guides to Saylorville Lake, the Neal Smith Trail, the High Trestle Trail, and Big Creek State Park.

Saylorville Lake, in our backyard

Along Johnston's northern and western edge sits Saylorville Lake, a large U.S. Army Corps of Engineers reservoir on the Des Moines River with swim beaches, campgrounds, boat ramps, and miles of paved trail along the water. When the reservoir runs high after heavy rain, the Corps' releases raise the river downstream - we track it in our river & lake levels guide.

The almanac

How Johnston began

The land was first settled in 1846, when Ezekiel Hunt built a sawmill on the west side of what is now Johnston. The community grew up around a rail stop - it took the name Johnston Station after John F. Johnston, an agent on the Interurban Railway - and the city formally incorporated in 1969. From a whistle-stop on an electric commuter line to a suburb of more than 24,000, in a little over a century. That's Johnston.
