Fish species in Thornton Lakes

Thornton Lakes is a lake in Whatcom County, Washington and covers about 52 acres.

Thornton Lakes can be broken down in a few passes: shallow cover, the first break, and the deepest useful water.

Fish and Baits

Fish listed for Thornton Lakes include Brook Trout, Brown Trout, Cutthroat Trout, and Rainbow Trout.

During a short evening pass near a soft-to-hard bottom change with stable weather, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.

During a check of nearby water near the edge of deeper water beside useful cover, work a small minnow bait, spoon, or streamer along cool breaks and moving water for brown trout.

How to Read the Water

During a cool spring morning near a soft-to-hard bottom change while the water is rising, use wind as a clue; a light push can carry food toward a bank, but hard wind may muddy it, so look for a clean edge near a point or protected pocket.

Season by Season

While using a short pass along useful shoreline near a clean gravel patch with a moving bait, spring fishing starts with warming banks, creek mouths, and shallow cover; summer usually pushes the better bite toward the outside weed edge or a nearby drop; fall can bring bait back to windblown points, while winter calls for smaller moves and a slower pace.

A Simple Tackle Plan

During a check of nearby water near a shallow shelf in clear water, a light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control.

During a steady fall day near a small drop with a slow lure, record the wind, water color, depth of the first good pass, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
