Fish Rainbow Lake

Rainbow Lake Rexburg IdahoRainbow Lake is located in Rexburg, Idaho. It originated as a gravel pit by the State of Idaho to build Highway 20 near Rexburg Idaho. It was later bought by a local individual that realized the potential this little gem offered. The owner later discovered that there were numerous springs that sprung into a 34 acre lake. Rainbow Lake is fed by natural springs with no outgoing or incoming water, therefore, making it a healthy clean environment for record fish. The water level rises and falls as the sub water also rises and falls as local farmers irrigate their crops. The owner first stocked the lake with Rainbow Trout, hence the name Rainbow Lake, and later added Small and Largemouth Bass. In 2004 two young Frenziers, Aaron “Chubbs” Peterson and Randy “Rudy” Garn bought the lake from the previous owner. Chubbs and Rudy grew up their whole lives fishing this little lake. Owning it was a dream come true. The plan was to have a private lake where friends and family could gather and enjoy catching record size fish. In late fall 2004 Chubbs and Randy introduced nearly 200 large Rainbow Trout into the lake. In 2005, they introduced about 50 infant Tiger Muskies. The lake currently boasts:

  • Near Idaho State Record Smallmouth Bass
  • Largemouth Bass
  • Rock Bass
  • Tiger Muskie (ranging from 30 – 40 inches in length, and still growing)
  • Record Rainbow Trout (some as big as 10+ lbs)

As you can see below, there are some huge fish in this lake. In years past this lake has been reserved for friends and family of the owners along with our fly fishing frenzy group. It is a catch and release with single barbless hook only fishery. This year the owners have decided to offer this gem on a limited basis to those that share their love for fly fishing for record fish. We will be offering a few permits to fish Rainbow Lake each month along with a giveaway on our blog for a free one day guided trip.
