wussup I got a cottage on Sparrow Lake in the bay just east of Lauderdale..
You got 2 launch points at the Blue swing bridge in the river or at Lauderdale marina
All the bays are roughly 6-12ft depending how close you are to shore. You'll mainly find pike, large and smallmouth bass and perch (senkos, spinners and top waters)
The mouth of the river is a good spot to fish (bring live bait)... pickerel, pike, catfish, perch, large and smallmouth bass, muskie, bowfin.. theres been reports of lake sturgeon too
Watch out for sunken island at the north part of the lake entering the river (its marked pretty well)... All and all I darn love fishing sparrow lake.
