British Columbia’s Interior Rainbow Trout Fishery on the Fly

Posted in General on by .


We are very fortunate here in our Province with the immense amount of incredible fishing opportunities that surround us 12 months of the year, and our Interior Rainbow Trout fishery is one of those incredible fisheries. Between the months of April and October, there are lakes that can be fished for trophy sized Rainbow Trout, with the Spring and early Summer months generally seeing the best fishing in this time period.




It is not uncommon to find trout exceeding the 10lb mark in various lakes throughout the Interior, and this is what draws anglers from all over the province to come fish these bodies of water. Another main attractor that draws anglers in is that these fish can be pursued very efficiently with a fly. On most days, a well presented fly will out fish all conventional gear methods.


Setup & Gear Selections

There really does not need to be a lot that goes into your gear and setup selections, but it is a good idea to make sure you are well prepared for a variety of scenarios. In the next few sections, you will see what you should be equipped with in order to get the most out of this fishery, and to be the most successful at it.


Fly Lines

Your fly line choices will vary depending on your method of angling, the depth, the time of day, current hatches, and what lake you are fishing.

Three lines you must not be without:

  • Full Floating Line (Does not sink)
  • Intermediate Clear (Sub-Surface)
  • Full Sink (Varying Sink Rates)

Full Floating: Full floating fly lines are designed for a variety of purposes in a lake scenario. This particular line has become a staple for Chironomid Fishing with indicators, Dry Fly Fishing, and Casting Wet Flies in shallower water.

Intermediate Sinking: A clear intermediate fly line can only be fished in certain scenarios, and is not going to seemingly be the most effective line at all times. ALTHOUGH, there are many cases where these lines are incredibly effective for fishing wet flies along shoals and shallower areas that trout may be feeding in. They give the angler the opportunity to present the fly very naturally to the fish.

Full Sinking: A full sinking line is one of the more common lines used when it comes to lake fishing trout, and is generally fished with leeches, chironomids, dragonflies, and more.



When it comes to fly fishing fishing the interior lakes, anglers should be fishing rods between the 9ft to 10ft range on average, with rod weights varying between 4 and 6 weight. While these are only guidelines, you can definitely stray from these recommendations and use a shorter rod for example, with a lighter line weight, although one thing to remember is you do want to match your setup to be the absolute best for the lake(s) you are fishing.



Reels should be capable of holding at least 50 yards of 20lb backing, and when targeting much larger fish, even upwards of 100 yards of backing can be ideal.

Fly Fishing Tools


A variety of tools are essential for your next lake outing whether it be a day trip or a week long trip. Things you will want to pack along to give you the upper hand include:

  • Forceps
  • Scissors or Nippers
  • Pliers
  • Measuring Tape
  • Stomach/Throat Sampling Kit (Stomach Pump & Glass Vile or Jar)
  • Gear Bags


Fish Finders

An absolutely critical tool when it comes to being a successful lake angler, Fish Finders (or Depth Sounders) will not impede any of fishing, but will only improve it. In order to find out your exact depth, read bottom structure, and even finding out where the fish are laying in the water column, having a good solid Fish Finder is most anglers key to success. With changing hatches, and ever changing water temperatures throughout the course of a day, anglers can see what is going on below the water surface, as opposed to trying to guess what is going on.

Fly Fishing Boats

Frameless Outcast Boat


Virtually a necessity when it comes to these lakes due to their contour and vegetation along the waters edge, a variety of boats may be used to give you the best advantage and upper hand when it comes to fishing successfully.

  • Outcast Inflatables (Pontoon & Frameless)
  • Watermaster Inflatables (Grizzly or Kodiak)
  • Spratley Aluminum Boats (8, 10, or 12 footers)



It is virtually impossible to name some flies that will be your best flies as when it comes to any Interior fishery, the hot fly can change hour to hour, or even minute to minute. As a general rule of thumb, general patterns include the following:

  • Chironomids
  • Leeches
  • Dragonflies
  • Damselflies
  • Scuds/Shrimp

Fly Fishing & Fly Casting Lessons

It can be a bit frustrating for a newer angler to try and pick up a fly rod and put the line and fly where they want it. Here at the store, we offer a large variety of courses to help get you dialed in, and especially dialed into this particular fishery. Two courses that may help you with this fishery if you are a beginner is our Beginners Fly Fishing School. In our Beginners Fly Fishing School, students will learn about Rods, Reels, Lines, Knots, Entomology, Flies, and Instructional Fly Casting. If this is something you have been at for a while, but would like to brush up on your casting skills, we recommend booking a Private Casting Lesson with our “C.C.I.” (Certified Casting Instructor) Brian Braidwood.

Fly Tying
