Summer Rainbows: Tactics for Catching Trout

By Mack's Lure Staff

Summer is one of the most enjoyable times of year to be on the water. Stable weather, long daylight hours, and family vacations make it the perfect season to chase rainbow trout across the Pacific Northwest's lakes and reservoirs. But while conditions are comfortable for anglers, they can present unique challenges when targeting trout. As water temperatures climb, rainbow trout adjust their behavior, often moving deeper and becoming more selective.

Success comes from understanding where they're holding, what they're feeding on, and presenting lures that trigger strikes. Fortunately, with the right tactics and the right gear summer can produce some of the year's biggest trout.

Think Outside the Box

By midsummer, rainbow trout have seen countless lures pass overhead. Fishing pressure is at its peak, especially on popular lakes, and trout can become conditioned to the same presentations day after day. That's why summer is the perfect time to experiment.

Changing lure colors, attractor styles, leader lengths, and trolling speeds can often be the difference between an average day and one you'll remember for years. Sometimes all it takes is showing fish something they haven't seen before.

Follow the Temperature

One of the biggest keys to summer trout fishing is understanding water temperature. Rainbow trout are most comfortable in water between 55 and 65 degrees. As surface temperatures rise, fish typically settle into the thermocline, where water temperatures, oxygen levels, and forage all combine to create ideal living conditions. Use your sonar to monitor water temperature and suspended fish. If your electronics don't clearly display the thermocline, increase your sensitivity until you locate consistent schools of fish. Then experiment by trolling just above, within, or slightly below that zone until the trout tell you where they want your presentation.

Fish the Structure

Summer trout aren't randomly scattered throughout a lake. Look for creek mouths, underwater points, weed edges, and sharp drop-offs where cool water and food naturally concentrate. Inlets deserve special attention because they introduce cooler, oxygen-rich water while washing insects and other food into the lake. These areas often attract baitfish, making them prime feeding locations for larger rainbow trout.

Contour maps are equally valuable. Fast-dropping ledges allow trout to rest in cooler water while quickly moving shallow to ambush prey. Trolling along these transition zones consistently produces fish.

Early and Late Still Win

The old saying about fishing during the first and last hour of daylight remains true, especially in summer. Early mornings and evenings offer cooler water temperatures, reduced boat traffic, and actively feeding trout. As the sun climbs higher, recreational boating, wakeboarding, and jet skiing increase dramatically, often pushing fish deeper into the water column.

Midday trout can still be caught, but anglers typically need to fish deeper and slow down their presentations.

Match the Hatch with Mack's Lure

One lesson remains constant regardless of the season trout feed on what they're seeing naturally. For surface-oriented trout feeding on insects during cooler periods, few presentations are more effective than the Mack's Lure Smile Blade® Fly, Koke-A-Nut™ Glo®, or Wedding Ring® Glo® Fly.

These proven trout producers closely imitate emerging insects while adding subtle flash and vibration. Pair these lures with a Flash Lite® Troll, Sling Blade™, or Double D™ Dodger to increase visibility and create the erratic action that often convinces following fish to strike. Leader length also plays an important role.

Dial In Your Speed

Rainbow trout are active predators that generally prefer faster trolling speeds than many anglers realize. A speed between 1.5 and 2.0 mph is an excellent starting point. Rather than trolling in a perfectly straight line, weave gentle S-turns across the lake. These subtle turns naturally speed up outside rods while slowing inside rods, allowing trout to reveal whether they prefer a faster or slower presentation without ever touching your throttle.

Get Away From the Boat

Surface-feeding trout can become wary of boat traffic, making lure placement just as important as lure selection. One of the most effective tools for spreading lines away from the boat is the Double D Dodger. Its unique design allows anglers to position presentations off either side of the boat while maintaining the dodger's signature action.

When fishing downriggers, longer setbacks of 100 to 150 feet combined with the Double D Dodger can move lures 20 feet or more away from the boat's path. Additional rods rigged with Sling Blades can be fished even farther back sometimes as much as 200 feet to cover untouched water.

When targeting deeper summer fish with downriggers, however, shorter setbacks of 20 to 30 feet often provide better control and reduce tangles while allowing anglers to precisely target fish suspended at specific depths. Adding a Flash Lite Troll directly to the downrigger ball provides additional flash and attraction, drawing trout toward your presentations.

Summer Success Starts with Confidence

The Pacific Northwest offers some of the finest rainbow trout fisheries anywhere in the country. From neighborhood lakes perfect for introducing kids to fishing to expansive reservoirs holding trophy triploids, every body of water presents an opportunity. The key is understanding seasonal fish behavior, adapting your presentation, and having confidence in proven tackle.

When you combine proven products with smart seasonal tactics, you'll spend less time wondering where the trout are and more time reaching for the net.
