Musselshell Salinity

The Musselshell Watershed Coalition engages volunteers in stream salinity and photo-point monitoring in order to identify and address water quality concerns in the Musselshell Watershed. During the irrigation season their dedicated core of volunteers use field meters to collect specific conductance readings at several sites along the Musselshell River. This data is entered in the MSUEWQ Data Hub where it is immediately available to the public and can be used to make irrigation decisions. The salinity data is also displayed on the Musselshell River Flow & Salinity website alongside discharge data.
