Chapter 1473 appear to have been contingent that an existing roadway be
built to State Highway Standards. To that end Frenchman Lake was
completed as a California Department of Water Resources irrigation project
by 1961 along Little Last Chance Creek. The existing Frenchman Lake

was adopted as the alignment of Route 284. Notably modern Frenchman
Lake Road appears on the 1935 Division of Highways Map of Plumas County
north of Chilhoot.
