USB and Alto-Alto visual guage

Posted on May 20, 2010 by Nick

I just installed a small visual guage on south boulder creek. it’s under the railroad bridge on river left just above Trainspotting. this guage works for USB and Alto-Alto. yesterday at 9am it read 7.5 inches. The confirmed flow was 230cfs at noon the same day. I’m thinking we’ll be looking for a guage height of 8″ for reasonable minimal flow on both runs. ELF levels down to 7″ or even 6.5″ maybe. Oh, and I did clip off the excess cable ties after I took the photo.
