Long Lake sits about six miles west of downtown Three Rivers — a naturally formed, spring-fed 211-acre lake that straddles the St. Joseph County / Cass County line. There are around thirty lakes called Long Lake across Michigan; this is the Three Rivers one, neighbor to Corey Lake and part of the same regional lake community. The Long Lake Improvement Association even holds its meetings at Corey Lake Orchards nearby, which gives you a sense of how tightly-knit the group of lakes here are.

Spring-fed water plus a mid-sized surface area gives Long Lake a quieter, more private-lake feel than the larger all-sports lakes in the region. It's a fishing-and-pontoon lake more than a wake-and-ski lake. For boaters who keep their boats at private docks and don't want to trailer six miles east into Three Rivers every time they need fuel, Dockside Fuel Service brings REC-90 straight to your dock — text LONG to (877) 257-FUEL to get on the schedule.
