Sycamore (formerly, Loch-loch) is a former settlement in Colusa County, California. It lies near the mouth of Sycamore Slough, at an elevation of 49 feet (15 m). Sycamore was a farming community in the late nineteenth century and once had a mill, church, school, and a nearby station on the Northern Electric railway branch to Colusa.[1] The Sycamore post office operated from 1871 to 1960.[2] Today nothing remains at the Sycamore townsite, which is located on California State Route 45 on the south side of its crossing of Sycamore Creek.
