A blog for runners in and about Addison County, VT

Authoring this blog has had the benefit of keeping me from getting in ruts (figuratively, not literally) on my runs – I can’t keep writing up the same routes, so I am constantly on the lookout for new places to run, or potentially interesting variations on old favorites.  Today’s run is an example of the latter.  My first run description early last summer described a route which skirted the north end of Silver Lake, a popular local outdoor destination and one of my favorite places for summertime runs.  I couldn’t help but notice numerous side trails which looked runable without pondering what their destination would be.  In particular, I have always wondered how to get to the curious structure visible part way up the ridge.  This smokestack structure, which looks like the remnants of a postindustrial redoubt on the hillside when viewed from the beach on Branbury State Park, had always seemed somewhat mysterious and elusive, but I reckoned that some of these trails must lead in its direction.

With this destination in mind, I pulled into the Silver Lake parking lot near Branbury State Park.  Descriptions how to find this parking lot can be found in the aforementioned Silver Lake post.  After a few minutes of climbing, I passed under the first pipeline crossing, but a quick assessment of the its path indicated that following it this low on the hillside would be more a challenging scramble than a trail run, so I continued up the main trail.  After completing most of the switchbacks and most of the climbing, I noticed a major side trail traversing the hillside to the right, so I made this turn rather than continue on the main trail as I had in runs past.   After a few easy minutes on this level trail, I reached the destination of my curiosity.

Mystery structure

I am still somewhat mystified as to the role of this tower.  I first presumed it was some sort of pumping station to bring the water from Silver Lake to the precipice required for power generation, but there were no sounds emanating from the structure indicating that is was actively doing anything, and I certainly was going to respect the “Keep off” signs on the structure and the small adjacent building rather than explore it further.  If any readers know the role of this structure, please post your insights.

A short jog up the grassy knoll behind this structure led to the pipeline itself stretching out into the distance.  Looking down at my feet I noticed that a small patch of opportunistic flowers had made themselves at home in the first of the massive fittings holding this pipeline together.  Perhaps my colleague at The Middlebury Landscape blog can inform us as to their identity?  It is comforting, however, to see nature reclaiming the woods without damaging the functionality of our necessary structures.  A little symbiosis is a good thing!

The Pipeline

silver lake pipeline 010 I ran along the top of this broad pipeline for a few hundred yards.  The footing along the pipeline was generally good, but in the few places where it was dicey, there was ample room alongside.  The pipeline eventually crossed the powerline clearcut, and a short run on the obvious path up this hill led to a beautiful viewpoint overlooking Lake Dunmore.  While this is not as airy a vista as the better known Rattlesnake Cliffs viewpoint, it does have the advantage of being open to hikers and runners during much of the summer when the Rattlesnake Cliffs are closed due to Peregrin Falcon nesting.

Completing the pipeline segment of this run, I came up to the base of Silver Lake Dam, looped around to its crest, and chose to circle the lake on this run.  My distant memory of less traveled trail along the west side of the lake was that it was rarely used, and pretty rough.  My distant memory proved correct!  While the next mile or so would have made for a pleasant hike, the rough rocky trail on a sidehill proved pretty much impossible to call a run, even by trailrunning standards.  Very slow going!  Nonetheless, persevering over the next mile or so to the south end of the lake provided a wilder view of the lake than most visitors get.

    That “strange” structure is the surge tank for the Silver Lake hydroelectric project. It’s basically a huge pressure relief valve in the event the flow through the penstock changes abruptly.

    Great blog btw!

    Hi Jeff,
    I really enjoy your column, as they revive fond memories of when I was younger and traveled many of the routes you write about. Keep up the good work. Peace JC

    Thanks JC! I hope you can find the time and ability to get out and relive some of those memories.

    Steve Costello from CVPS just sent us a response to your question about the pipeline. Looks like you’ve already gotten this answer, but here’s what he says:

    “The tall black structure is a surge tank for the CVPS hydroelectric
    facility at Silver Lake. The tank is normally empty. It is designed to
    prevent damage to the penstock, the black pipe that runs along the ground
    from Silver Lake down to Route 53 near Branbury Beach. It works by acting
    as a relief valve. Put another way, if pressure gets too high in the pipe
    due to a sudden shutdown of the system, the surge tank allows water to go
    up inside it, taking the pressure off the penstock itself. You’ve
    probably seen the giant black tower along Route 7 in Rutland Town, just
    before the city of Rutland. That is a larger version of the tower below
    Silver Lake, and serves the same purpose for a penstock that comes down
    from Chittenden to Rutland.”

    Thanks for your effort in digging up the answer Andrea!
