East arm is an excellent choice for a bass opener trip. The smallies there are skillfull fighter's and will test your gear. The bass will just be moving off their redd's and be in attack of the many baitfish in that deep spring fed lake, concentrate on the shore lines and drop offs not to far off, there are some excellent sunken logs and boggy lilypad areas back in Annie's bay. I have had great success with just conventional jerkbait's this time of year, cast toward shore and cover areas and rip hard through. (Bring some rapala's perch imitations, deep diver's, suspending whatever), sunset/ cloudy days are good to bring some topwater out. I have found the East part of the arm the best, but they are strong populations throughout, concentrate on inlet too Annie's Bay and all through it. No need for too much gear, simplify...Suggest a watertaxi to a site near, this is a long trek from the outfitters. Call Opeongo outfitter's they will fix you up. Have fun
