West Fork updated 4 remote PIT antenna sites for the Kalispel Tribe in tributaries of the Priest River in Idaho. These new antenna arrays are an upgrade from the older half duplex system and provide a reliable data set for the monitoring of Westslope Cutthroat Trout in the watershed. These new sites operate on the IS1001 reader and MTS system as well as a robust solar array to power the sites all year.
