Here's a mini ride report buried in the DAM-IT! thread:
A short ride less than 1/2 mile from my house, including two earthen dams, two multi-hundred acre reservoirs, an 8300' penstock, a water tower, and a 5 Mw unmanned power plant. All right in my town, I live less than 1/2 mile from one of the reservoirs.
We'll follow the water...... That powers Green Mountain Power, Marshfield Station No. 6.
We start here, Peacham Pond. Manually controlled.
no overnight camping, but dirt bikers are ok.
crank handle for valve
water comes out here:
Next stop, Marshfield Dam (Mollys Falls Pond) second reservoir in the chain.
This is located off of US Rte 2
The gate here has a house. No access to this one, gated off. So sad.
Water comes out here:
The start of 8300' of wooden penstock.
Who wants to climb in first?
here it goes underground, crossing US Rte 2
coming out the other side:
Last summer they replaced some of the old wooded penstock with steel. Here is where they meet up:
looking the other way, towards the water tower:
from the water tower, the water goes here:
water exits here: (power plant is "offline" in this shot)

Here's a really cool engineering link to the re-building of the vertical Francis turbine a few years back. This stuff intrigues me, so if this is a bit much detail, so be it.
The whole system was built in the late 1920's, privately, by Green Mountain Power before the depression work program era stuff started up.
