Rock Creek Stream Flows

In spring, river flows tend to be quite low. As the snow and ice melt, flows can fluctuate and trend higher in April. Pre run-off trout fishing can be very good, especially if stream flows rise gradually. River flows can spike following a big rain event or temperatures above 60 degrees and/or nights that do not drop below 32 degrees.

Run-off

High water, also known as run-off, occurs in May and can last into June. Typically in late- May or June, the water clears. Although it can still be high, clear water is often very fish-able water. The salmonfly hatch occurs in early June and is best fished from a raft.

Summer and Fall

Rock Creek stays clear with a steady but slight decline in the river flows. Seldom affected by Hoot Owl restrictions, Rock Creek enjoys cool water temperatures due to the narrow and tree-lined canyon. In autumn, the cottonwoods along the creek become brilliant yellow; a stunning backdrop for a Montana fly fishing trip.

Winter

The creek can be fished in winter. Choose wider sections of the valley where ice does not form. Fish low and slow.
