Flows are bouncing around below Gross Reservoir, but as of this posting the flows are amazing. Flows are currently hovering around 90cfs, but keep an eye on the gauge in case they make a big increase/decrease. Midges and BWO's are what's hatching right now, but don't be too surprised to see a caddis or two. Like Clear and Bear Creek, we like to start with a light hopper-dropper setup to search for fish. Once we see them rising, we'll switch over to a single dry.
