From the record
“The Logan/Esterly Upper Ditch is an abandoned, artificial watercourse in the Illinois River Valley of northern California and southern Oregon, United States. Built in 1854 to supply water from the river's East Fork in California to several hydraulic mines in Oregon, it quickly returned a large profit to its investors.”
