This was my first visit to the Middle Fork Nooksack River Road. It's in great condition fr the first few miles - which is all I needed to drive before I located the spur road to the diversion dam.
The diversion dam was reportedly built to divert water from the Nooksack River and into Lake Whatcom... for the purpose of ensuring Lake Whatcom will be around for a long time as it is a staple water source for Bellinghamsters.
The spur road descends about 400 feet to the dam over the course of .75 mile or so. The road is heavily eroded from water, making it impossible for vehicle travel (except the uber-4x4's, ORV's or maybe a tank). It doesn't matter though, because the road is blocked with a gate.
I was surprised to find the bridge over the river and I was surprised at the size and complexity of this diversion dam. Much more to it that I would have anticipated and I really wish I had someone with me who could provide more info about the design. Why is it so complex? So intriguing. Such a mystery.
The river channels into a pretty deep gorge after it passes by the dam. It's hard to tell from the bridge whether the gorge is natural or whether it was created/modified as part of the dam construction.
I think I pinpointed where the diverted water goes into the tunnel, but it's just a guess... and I have no idea how large of a diameter the tunnel is. Six feet? 20 feet? 50 feet? No idea.
Also, where is the other end of this tunnel? There must be an access point at the other end, right? Somebody had to build something down there... where is it? Better add that adventure to my "Rainy Day Dumpster Dive To Do List".
This was a neat little adventure to an area that is new to me and I'm looking forward to more adventures and explorations further out the Middle Fork road in the future.
Here's a video with most of the above pictures, but also some real video footage I recorded while at the dam.
Happy Trails!
