May 10 on the Bitterroot River – flows are stepping up

May 10 on the Bitterroot River – flows are stepping up

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.

Links to snowpack and USGS river flow gauge stations are in the right side bar.

2012 spring runoff has begun in Bitterroot River late April

2012 spring runoff has begun in Bitterroot River late April

Air temperatures were in the 70 degree range beginning about April 20. These photos were taken April 24. Look at the graphs and you can see how the rivers have been rising. The last two days the Bitterroot Valley air temperatures have been over 80 degrees. These photos were taken when Bell Crossing flows were at about 4,700 cubic feet per second (cfs) – 2 pm. Right now it is 6:30 pm and the flows at Bell Crossing are at 5,480 cfs. That is a big jump. The gauge downriver (north) near Missoula measured 8,190 cfs at 8:45 am and now at 6:30 pm it is measuring 9,280 cfs – closing in on 10,000 cfs!!!
The snowpack in the Bitterroot River Basin earlier this month was over 100%. Today it is 89%.
The photos are all taken from Bell Crossing starting upriver looking southwest and rotating counter-clockwise to the east, then south, finally southwest into the parking lot. As I was there, a LOT of large woody debris was moving down the river.

Here are photos of the Bitterroot near Bell Crossing on February 26, 2012. The cubic feet per second (CFS) was about 570. Temperature was in the low 30 degree range. Beautiful day. We like to give the fish a break in the winter while they are struggling to survive the cold, low water but I do like to chronicle the river in photos. Interesting to look back from year to year and compare winter conditions with spring, summer, and fall fishing observations. We love our rivers and all that lives in and on them. It is exciting to watch them as they change through the seasons.
All the river photos are taken from Bell Crossing Bridge looking north.
