Hi guys, I am looking for some advice. I have access to about a 40 acre lake, that I know, or feel, has to have some good size crappie in it. Problem is, I have only caught 3-4 the last several years, but I can catch hand sized fish quite often. How do I go about locating these bigger fish, and when would they start getting ready to spawn in a lake of this size? As of right now, I don't have a depth finder, but seems like the average depth is around 15-18ft,as I have run jugs in this lake. I have found some submerged timber, but it seems like that it usually has a thick grass mat all around it, and along the shore. This is an old watershed, and has a rock lined dam, but there agian, it usually has a grass mat around it. Can someone give me some tips on how ti fish it? I am currently looking for a small cheap depth finder to use on my little jon boat. Thanks guys!!
