How to read the Tremont Gauge
So they cut the bottom part off of the bottom meter, the middle and top meters are fully present.
So each meter stick is divided into 10 units, or 10 decimeters. Each decimeter is marked with 10,20,30, etc. as you go up the meter. These numbers indicate height in centimeters. So at any medium to low flow, the water will be somewhere on the bottom meter stick, and if it is on the middle meter stick it is medium to really high. If on the top, you may not be able to drive up the road.
We ran it on Sunday at what was considered a fun minimum. This was 82 cm on the bottom stick. So 80 cm, or 0.8m is a good minimum. Let the next meter stick be 1.0m through 1.99m. So if it got on the next meter stick at say, 20cm, that would be 1.2 meters.
Now we can start dialing in what different levels on tremont mean to each and every one of us, and instead of high and low being thrown around, actual concrete numbers can be used to convey river levels, despite inconsistencies in interpretation from one person to the next about what the number might mean.
My guess on levels are something like this:
80cm, or 0.8m - minimum
90cm, or 0.9m - a good low
100cm, or 1m - a medium low
110cm, or 1.1m - solid flow
130cm, or 1.3m - medium high
150cm or 1.5m+ - high
Lets dial this in.
