Where do I find a table to read a parshall flume with a 4 foot throat
Ravalli County Montana
This question recently came to me and is outside my expertise. Unfortunately, I do not have a reference for you. I am only vaguely aware that the devise is for in-stream flow measurement. I would suggest searching further online for a USGS or USDA-NRCS office in your county or area of the state for the reference you seek. You may also inquire if there is a hydrologist at the UM Forestry School.
I am sorry to not be of more help.
