There is a small [175 acre] water supply reservoir about 45 min. from my home in central Indiana. It is 2 to 3 ft deep on the river end, and about 25 ft on the dam end. Most is quick drop off with some cover in shallower water, not really very weedy, and visibility usually  around 6 inches to a foot. I have fished this place the last 2 falls, from 1st of October to Thanksgiving and have done fairly well, having some of the best number days of my year, and I have caught 5 lb largemouth. Problem is, for some reason, I dont do worth a crap in the spring or summer. Using the same methods I use in the fall will not produce the same results for me, and I have tried different lures, presentation, ect but cant seem to do any good, many times getting the big skunk.  Wanting to get out this weekend, air temps are forecast mid 60s on Sunday, I dont know what the water temps are, but I was wading in a local river 2 Sundays ago and the water temps were [or at least felt] warmer than what they did on Christmas day. I did catch several bass on an small inline spinner. I am guessing 50 maybe. Any ideas? I know there are quality fish in this reservoir, I just cant figure out why I do so well in the fall, but suck so bad in the spring.

Spring for me is spinnerbait and bladed jig time when the water gets above 50 in smaller bodies of water. Fish will be surprisingly shallow as they try to soak up the warmth from the sun. I'd look for areas of shallower water near deep water, especially those that are hit by the midday sun. Dragging a dark colored jig can be a good way to get a big bite as those big females are looking for those slow moving and protein rich craws to help with egg production.
