Specific information for catfishing in the Boyer Park area below Lower Granite Dam

Below Lower Granite Dam there is access on both sides of the river for about a mile. The south side of the river has some decent fishing around Illia Landing (boat launch).  The water here is fairly deep close to the shore and the Catfish will travel along the drop off as the move up and down the river. 

From Illia to the dam - any area you have a point of shore line jutting into the river or an obvious cut line where there is a flow change you will probably find catfish. This type of water condition gives the fish an area where food tends to settle. 

The north side of the river around Boyer Park and the grain elevators upstream to directly below the dam can also produce cats. You are again looking for any area that presents a potential feeding area. 

Cats will congregate and feed in the vicinity of the grain elevators. They predate small fish or actually eat the grain itself when it is available.

There is no one place that will always produce fish as they tend to migrate throughout the entire area. You will need to try spots and be willing to move if there is not fish in the immediate area you are fishing.  

  • Recommended equipment:
  • Fishing rod that is capable of casting at least 2 to 6 ounces of weight.
  • Line weight 12 to 15 pounds.
  • Recommended hook would be 2/0 Khale hook.


If you only fish quieter water then a lighter rig will work but it will limit potential fishing areas.

Catfish will aggressively feed during the early part of the day and night fishing can also be very productive.
Become familiar with the roads and shoreline on both sides of this area. Either side can produce some nice catfishing so do not limit yourself.


  • Baits that produce consistent results in catching catfish in the Snake River are fresh cut bait. This includes trout parts, Smallmouth Bass parts, Pike Minnow strips and sucker strips and fresh liver. Bait should be fresh and as bloody as possible. Replace baits often. Worms are always good but this bait will bring bites from every fish in the vicinity. Empty hooks are the result.
  • Use river maps to find channels and drop offs.
         Fish edges marking depth changes. Catfish use these edges to find food and it a natural                        area for their travel.
  • Feeding Activity.  Catfish in the impoundment areas will often feed during the day time hours with a decrease in the bite usually noted during the midday (11:00AM - 3:00PM). Mornings and afternoons can produce numerous bites and should not be ignored.
          Catfish in the free flowing areas of the Snake River tend to bite primarily during the night,                                very early in the morning with limited activity during the day.
         The bite can be tentative and very light in the slack water areas, setting your rig up to slide                             through the weight will allow fish to pick up and move with the bait. This will result in better  and more              successful hook ups.
  • Use stretchy thread to anchor the bait above the hook to prevent cut baits from covering the hooks point.
  • Main lines heaver than 20 pounds are not necessary and can be counter productive when the fish are not aggressive in their feeding.
When fishing for Catfish if you find an area that produces fish, pay attention to water conditions, depths of the river and flow patterns. If you see the same conditions in other areas they should be your first choice in trying new spots.

In many areas of the impounded waters there are fresh water clam beds. These can be outstanding areas to find fish as catfish will utilize clams as a food source. Fishing slightly down river from the beds you can intercept catfish coming into the area to feed.
