Elk Bend was originally established in the mid-1960s as a collection of real estate development projects. These projects were named the Salmon River Estates, with Salmon Meadows and its annex added later. While land was purchased and held on to for years, most development of the community didn't occur until the early 2000s, when residents who had previously bought land in the area reached retirement age and built houses and manufactured homes to retire to.
