And now, finally, the ascending upward trend in the run-off from the upper South Fork Boise River Basin. Flow usually peak just after Memorial Day.
Thanks to Art Butts at Idaho Fish and Game we have the data of the rainbow trout fishery from the last five population sampling efforts, conducted every three years since 1997. We display each sampling effort in a separate chart and it automatically cycles through the slide show.
Each chart displays the percent distribution of trout by size for each year of sample. The information is useful to visualize shifts in population characteristics.
A couple of warm days signals the beginning of spring run-off. And a set of charts assembeld above provides insight on what the near term holds for Anderson Ranch Reservoir. And there are implications for the South Fork Boise downstream of Anderson Ranch Dam.
Here’s a rather unexpected fly fishing video from the South Fork Boise River.
It’s a water short year measured by snow in the mountains, but Anderson Ranch Reservoir has more water stored than last year.
Woolly Bugger Meeting
Tuesday, December 15, 2009, 6:30 p.m.
Idaho Fish and Game Department Headquarters, 600 S. Walnut St.
Program: Archeology of the South Fork Boise River, the Danskin Rockshelter
“There is more to fishing than catching fish,” is the Woolly Buggers’ slogan. We believe it is important to know the history of our rivers, lakes and streams. Knowing what happened before our time adds to our enjoyment when we go fishing.
The above illustration is from the report Genetic evaluation of population structure and individual movement of rainbow trout in the lower South Fork Boise River and associated tributaries.
Make plans to attend an open joint meeting of TU and Boise Valley Fly Fishermen on Thursday, November 12, 2009 at the Boise Public Library to see a presentation on the genetic profile of the South Fork Boise River (SFB) fishery as well as hear a panel discussion of agency and angling community perspectives on Southwest Idaho’s greatest fishing water. Doors open at 6:30 p.m. and the program will begin at 7:00 p.m. Enter in the doors on the 8th Street side at the southwest end of the building.
Helen Neville with the TU national science team based in Boise will present her findings based on the laboratory analysis of the genetic information sampled from more than 300 rainbow trout, and compare that information with dozens of wild trout populations in the North and Middle Fork Boise Rivers.
Idaho Fish & Game, the Boise National Forest, Bureau of Reclamation, TU and BVFF worked together in 2008 to sample the SFB fishery and adjacent tributaries to gather genetic information on redband or rainbow trout. The information presented November 12 will provide a foundation by which a conservation strategy for the SFB fishery could be developed.
