Angler on Lake Pend Oreille with rainbow trout

Interested in winning prizes for fishing? The Lake Pend Oreille Angler Science Program might be for you!


Anglers on Lake Pend Oreille can enter to win prizes by participating in an Angler Science Program for rainbow trout (also called Gerrards or Kamloops)

If you have spent much time fishing on Lake Pend Oreille, then maybe you’ve been lucky enough to catch a monster rainbow trout. If not, you’ve likely seen pictures of the truly impressive fish that reside there. 


In recent years, Lake Pend Oreille has been producing more rainbow trout over 20 pounds than anywhere else on Earth! This world-class trophy fishery is firing on all cylinders right now, and Idaho Fish and Game is working hard to keep it that way.   


To effectively manage this trophy fishery, Fish and Game monitors the rainbow trout population and angler fishing success; however, it’s hard to get all the information we need through traditional fish survey methods.

Anglers, this is where you come in - we need your help! Fish and Game is inviting fisherman to participate in an Angler Science Program where we work together to gather information that will help us manage the trophy rainbow trout fishery. 

The Lake Pend Oreille Angler Science Program is comprised of anglers who help Fish and Game collect monitoring data for fish in LPO, mainly through completing logbooks and reporting tagged fish.


To-date, we have learned some important information from the Angler Science Program. For example, we learned that 17% of the fish caught in 2021 were larger than 30 inches, compared to only 7% in 2020.

To sweeten the deal, you can win great prizes by participating in the program!


What you can win

By participating in the program, you will receive a custom Lyman lure and sticker. In addition, you will be entered into a free raffle for the following prizes:

  • Yeti Tundra 45 coolers
  • Bubba electric filet knives
  • Work Sharp electric knife sharpeners
  • Custom RTIC 20 ounce tumblers
  • Custom hats



How you can participate

Complete a fishing logbook – Anglers must record information while fishing for rainbow trout on Lake Pend Oreille during two time periods that coincide with local fishing derbies. 

  • Nov. 2-6 the Lake Pend Oreille Angler's Club is hosting its Fall Derby
  • Nov. 19-27 the Lake Pend Oreille Idaho Club is hosting its Thanksgiving Derby

There will be a free raffle associated with each time period for participants who submit their logbooks by Dec. 10.  

Rules for the raffle are the same as last year, but logbook pick-up locations have changed. Logbooks will be included with the purchase of all derby tickets. If you are not participating in a derby, don’t worry. Free logbooks can be picked up at the Panhandle Regional office at 2885 W Kathleen Ave in Coeur d'Alene. For full details, check out this link.

Report tagged rainbow trout –To better understand rainbow trout catch rates, harvest rates and survival rates, Fish and Game is conducting a tagging study in Lake Pend Oreille.


If you’re fishing on Pend Oreille, please keep your eye out for tags located in the backs of rainbow trout.  Each tag has a unique number printed on it, as well as a phone number, URL and reward value (on select tags only).

Tags can carry a reward value of $25, $50, $100 or $200, so cross your fingers and hope you catch that reward fish!

If you see a tag, please report the tag number and location of where you caught the fish to Fish and Game.
