Big River, Mendocino – Aftermath of Flood

In the late 1800’s and early 1900’s there were quite frequent floods along the Mendocino coast. Whilst I haven’t actually found pictures of places flooded I did find this pic which shows what had to be cleaned up after a flood on Big, River Mendocino.

River Log Drive

Alas, I have yet to find a vid of logs being “driven” down Big River in Mendocino – the only river along the Mendocino Coast susceptible to such an operation. I know logs jams were routinely “blown up” with gunpowder – I have pics of that happening. Therefore any vid showing a river log drive is definitely of interest. This clip is an excerpt from “Timber on the Move: A History of Log Moving Technology,” a documentary film from the Forest History Society: https://foresthistory.org/documentary…

Hell’s Gate Dam on Big River

Dams were used by the Mendocino mill on Big River to bring the cut logs to the mill. The Mendocino Lumber Company was “famous” for damming Big River. With rare exceptions, dams along Big River were used only during the winter season. Logs were stored in the stream beds. Winter rains furnished the freshet (body of water) for floating the logs down river, but in most cases, did not. Dams were then used to build up a reservoir of water. When the dams were tripped (blown up), a flood was created along with a “head.” A head is similar to the shore side of an ocean wave. Near the dam, a head might begin as high as 10 feet dropping to three-foot height 15 miles down river. A higher head, which would result in being able to float more logs a greater distance, would be obtained by tripping/blowing up more than one dam in succession. This, for sure, was in the days before environmentalists were invented.

We have modeled Hell’s Gate dam on our layout without much help in the form of old photos. Hence these three photos will be very valuable when we work on our Big River diorama in the coming winter. Click on the photos to enlarge them
