Cold Spring, High Snowpack Means Late Runoff For Anglers

California’s snowpack remains stubbornly opposed to melting, and the latest figures are startling; the Northern Sierra snowpack/wetpack is at 465% of normal for this time of year (May 31). What’s it mean? It suggests California’s fly fishermen will be seeing high runoff…

California’s snowpack remains stubbornly opposed to melting, and the latest figures are startling; the Northern Sierra snowpack/wetpack is at 465% of normal for this time of year (May 31).

What’s it mean? It suggests California’s fly fishermen will be seeing high runoff flows far later than normal — and that the flows on many rivers now are only precursors of what’s to come.

What’s going on?

Couple a record snowpack (170% of normal at the end of the April 1 snow year) with a very cold, wet spring, and you have a situation where the snowpack is melting very slowly. In fact, recent cold storms have added to the snowpack at higher altitudes.

With rivers like the Upper Sacramento — which often features flows in excess of 10,000 cfs this time of year — still flowing around 2000 cfs, it’s clear that anglers better fish now, because once high flows arrive, they’ll stay high for some time.
