Welcome to the forum! If you don't have one, get yourself a paper topo map of Eldorado so you can study depth changes in areas you are able to fish.....creeks and coves will be your main areas. The map will also show you old roads leading down to the lake. You can launch a small boat in places like that so you don't have to be out on the main lake. If you can afford it, and your sonar can display it, a map card is really great when out on the water. Look for cover on creek ledges and where there are a lot of contour lines bunched together on the maps. This indicates a steep drop/rise. Dropping a buoy at a brushpile and then tightlining a jig or minnow is a lot of fun, and you will enjoy it as much as casting for crappies in springtime. Good luck!
