I fishh island lake alot during the winter it is closer for me then other lakes the average depth you will fish is 5 to 8 ft real shallow they have pike perch bass and crappie pike are small a big pike out of island lake is anything over 24inches 29 inches being my biggest i have got a perch out of there up to 13 inches
but they are usally anything from little dinks up to 10inches i dont get much crappie there but if you can find them they can get fairtly big i have seen 18inch crappie come out of the lake we get a bass every now and then out of season of course have to go back bass range from 2lbs to 5lbs have seen bigger come through the ice
i usally use tip ups or jigs for pike and minnows for perch and crappie not huge fish in the lake but there lots of them i have had 20+ pike days and about the same for perch hope this helps
