Here's an easy set-up for you and your kids to try:

Main line to a three-way swivel, 30" of leader attached to a small "Wicked Willie" spoon (hot pink on one side, pearl white w/ small red dot on the other), and 8"-12" of dropper to a small one-ounce cannon-ball weight. Might need to adjust the amount of lead depending on the river flow.

If you find a good place to anchor up in a humpy travelling lane, you should have some good action. Just make sure you're working your weight down on the river bottom, letting it bounce a little bit.

This is a proven set-up a certain guide-friend showed me years ago, and proven to catch many a humpy on the lower Skagit.

Enjoy those little ones while they're still young. My little fisherman isn't so little any more...and he out-fishes me most of the time.

Good Luck \:\)
