MONTANA SNOTEL Snow Water Equivalent Update Feb 2013

Snow pack in the Bitterroot is 82% of normal as of today, Feb 25, 2013. Right now, a winter snow storm just blew in and there is a white-out outside my office window. That is GREAT news!
Here are the tables showing the data. See the links below the photos for the NRCS site.

May 16 Bitterroot 2nd runoff pulse

May 16 Bitterroot 2nd runoff pulse

Bitterroot air temperatures have been in the high 80’s for the last three days and the snow melt is increasing the river flows. The air temperatures are supposed to drop in the next few days and rain is predicted next week. This will be interesting.

Here are some photos at Victor Crossing taken the afternoon of May 16.
Victor Crossing is about 5 miles upriver from the USGS water data gauge
at Bell Crossing and about 40 road miles down river (north) of the USGS
water data gauge at Darby. Below are photos of the river at Victor
Bridge, the charts for both gauges, and a snow pack map.

The Bitterroot had clarity on May 7 and still on May 8 – also terrific caddis hatches! But now the weather has been much warmer and the flows are stepping up. See the charts below.

Bitterroot River on May 7 north of Angler’s Roost
Darby gauge station is upriver from Angler’s Roost – on May 7 flows at Darby were about 1900 CFS
Bell Crossing gauge station is downriver from Angler’s Roost. On May 7 flows were about 3,000 CFS
Still snow in the mountains!!! Bitterroot is 89 % of normal.
