Eldriedge Bar is on the Willamette River about three miles downstream from Wheatland. It got its name from Freeman E. Eldriedge, pioneer settler on French Prairie who came to Oregon by way of California in 1846-47. Eldriedge School, north of Waconda, was named for the same man. The original school is now a church and a newer school has been erected near the old site.

For a time during the 1850s Eldriedge rented his farm near the Willamette River and operated a grist mill at Parkersville about ten miles eastward. He was instrumental in having the Parkersville post office established and was the first postmaster.
