Boise Valley Fly Fishers
Since 1971



BVFF sponsors several angler challenges as part of the BVFF Education and Conservation programs.  These challenges are designed to give BVFF members another reason to go fishing and to build fellowship among the members, as well as learn more about the native trout and other fish species found in and around Idaho.

There are currently five challenges.  BVFF members completing any or all of the challenges will receive a certificate and be identified on the BVFF website in recognition of their achievement.  Information on each of these challenges can be found by following the individual challenge page links.

BVFF Idaho Arctic Grayling Challenge:

Catch and release an Arctic Graying within the State of Idaho with a fly with a barbless hook using fly tackle.

BVFF 20/20 Club:

Catch and release a 20 inch fish of any species on a size 20 or smaller fly with a barbless hook using fly tackle.

BVFF Popper-Slam Challenge:

Catch and release a Largemouth Bass, a Smallmouth Bass, a Bluegill, and a Crappie using a top water fly and fly tackle.

BVFF Idaho Cutt-Slam Challenge:

Catch and release 4 native subspecies of cutthroat trout using fly tackle and single barbless hooks.

Idaho State Record Challenge:

Break one of the Idaho Catch & Release records for any fish using fly tackle.

Whitefish Derby:

This is an annual outing event and a challenge, and has been a traditional outing since the founding of BVFF.  One winner each year is honored for catching the largest whitefish during the derby period.  In recent years it has included both an outing event and a virtual derby time period to address concerns with the COVID-19 pandemic.


IDFG has created an online planning tool for finding a location in Idaho that will provide your best opportunity for catching a target species.  The fishing planner provides interactive information for locations, species observed or stocked, stocking history, and topographical maps on the locations.

Note that the BVFF native angler challenges are for native trout species, but are not currently restricted to catching them in native waters.  IDFG stocks many high mountain lakes which are not historical environments for these Idaho native species.

Safe Fish Handling

BVFF is a supporter and strong proponent of Catch-And-Release angling.  We encourage the safe return of all fish caught, and to handle fish properly for their best chance of survival.

Please consider the following:

  • Use a net to reduce stress on the fish.  Rubber nets are the best.
  • Don’t drag fish onto the bank, it’s hard on their head and gills.
  • Wet your hands before handling the fish and keep your fingers out of their gills.
  • Keep the fish wet. Minimize time out of water.
  • Have your camera and ruler ready
  • Give the fish time to recover before release.
