I have to say I would never take a fishing report to heart. Many folks post bogus stuff to make themselves look and feel better or just the opposite, they dont want others on the lake so they say there are no fish.
as for how to locate the active fish–there are so many things to learn that in a life time you wont know all the secrets.
some folks will look for the first group of boats and do the “monkey see–monkey do!” kind of thing.
That works now and then and is ok if you are only going to fish this lake once a year.
If you plan on fishing a body of water often, then you will definitely want to dissect the lake starting at home.
get yourself a map and/or an H2o unit.
I know for “eyes”, they are always going to go where the forage is. You’ll need to know what the forage base is in your lake system. If there is shad or cisco’s, expect some kind of suspension going on at least some of the time.
if you are dealing with bullheads, perch, crayfish, etc, then know when and where they will spawn and what they do throughout the year. where do they congregate.
I have to say, that for walleyes, there is a 5 book series called “Critical Concepts” that has turned my walleye fishing around. I can honestly say I have increased my catch rate 10 fold after reading these books. I take them with me when i go for a week long trip into the northwoods just for reference.
You can ask at a bait shop, but remember the bait shop guy is stuck in his shop and is getting his info from other anglers. He might be able to tell you where they spawn, when they spawned and some weather patterns as of late, but his info is limited as well.
you will also need to take the lake type into consideration. Is is Oligotrophic, Mesotrophic or Isotrophic? Is it some of each and what does that mean to you?
Keep in mind that in any body of water, not all fish are doing the same thing at the same time. fish in one area may be responsive to leeches while others across the bay prefer red tail chubs on a jig, and others may prefer more of a slower presentation such as a slip float and crawler.
I wouldn’t go by what is happening on another lake because no two systems are the same. The only info i would take from a different lake is the date of spawn if they are located within an hour from each other. Water temp can very by more than 10 degrees in a single body of water so taking two different bodies of water and comparing them is like apples and oranges.
