http://www.dnr.state.mn.us/lakefind...apid=B0050 And this map in particuilar...
http://files.dnr.state.mn.us/lakefi...050011.tif Leech has a MASSIVE amount of structure...depending on the wind...and water temps PRIOR to when you get there...there COULD be several things happening.
Since you are targeting ALL species...look for areas on the map that have MANY kinds of structure CLOSE by.
In other words...IF you can target a small area that has a point...and a couple of underwater humps (islands)...AND both shallow AND deeper water nearby...IMHO..that area would get you action of SOME kind for sure.
