Oregon bass anglers don't necessarily envy those in Southern California or Texas, because they have Tenmile Lake. And in August, the largemouths begin an aggressive bite. The lake has produced bass up to 10 pounds, with the average fish weighing in at around two or three pounds. Your best bets are Yamamoto Senko soft-plastics, crankbaits and spinnerbaits. A brown or black five-inch Senko worm-something that falls slowly and evenly to the bottom-is a local favorite. Use a 3/0 Eagle Claw Featherlight hook, rigging it weedless. The lake has a variety of structure and cover including deep water, weeded shorelines, isolated points and docks that can all produce bass. A top tactic is to target fish in the outside weed lines in about 10 feet of water. Rainbow trout are also available in the lake, with fish averaging 14 inches. Light spinners such as Rooster Tails and Panther Martins work best in a slow retrieve. Cast to crappies and bluegills with small, white crappie jigs in the canal joining North and South lakes. Catching 20 to 30 bass per day is possible. There is a limit of five bass a day, no more than two over 16 inches. The first weekend in August is the annual Tenmile Open, a two-day bass tournament open to all anglers. Contact: Oregon Department of Wildlife (503-872-5252); Lakeside Hardware & Tackle (541-759-3448).
