SubAgency Diversion Fish Ladder

The SubAgency canal diverts water from the Wind River near the town of Riverton in Central Wyoming.  During an upgrade of the diversion, OneFish designed and helped oversee construction of a fish ladder which was integrated the new diversion structure.  In a separate project, OneFish installed a real time flow monitoring system on a Parshall flume on the SubAgency canal (see Wind River Gauging).
