Popular Fishing Methods

Fly: Excellent fly fishing for trophie trout particularly rainbow trout, although browns are also stocked in good numbers. This lake offers great dry fly fishing when the weather is not to hot. White Moths work very well on dusk, while beetle, ant and grass hopper patterns work better during the day. Wet flies and sinking line are a must have at Thompson Creek Dam in the summer months so you can get your flies down deep around the quarried areas where the water is deep. Although midges and ant hatches can attract fish to the surface on the odd hot summer day. Best wet flies are dark coloured Woolly Buggers, and Fuzzy Wuzzy’s, as well as Zulu’s.

Spinning: Tassie Devil’s are by far the most popular and successful lure used at Thompson creek dam. Gold and pinks are the best colours with a slow retrieve. Shallow diving minnows in trout patterns work well in winter, while large Celter’s are better in the warmer months. To hook a large brown try a very large trout minnow.

Bait: No bait fishing permitted.

Boat: Boating is not permitted

Best Fishing Locations: At the base of the dam wall at the western side, the deeper quarried areas and weed beds on the eastern shore line. Most areas of the lake fish very well, so just walk the edges until you find where the fish are holding. Summer beetle hatches offer great dry fly fishing. Winter offers excellent sight fishing in close.

Camping: No Camping or Toilet facilities are available. Camping is not permitted.
