i was wondering what would be the best lure for catching walleye, and not just the lure, but the color pattern they like most..  preferably for a heavily weeded lake?... and id also like to know the time of day when they are biting the most?

 Best catching time for me has been at night, chrome cranks close to the bottom.

about what time at night?.. sun going down, just before it comes up, or right in the middle?.. and do walleyes typically prefer lighter colors like silver, white, etc?

I've caught hundreds of walleyes, but not from conventional walleye water. Most were from the murky waters of the Erie Canal with a maximum depth of 10' or so. I used crankbaits 90% of the time and grubs on jigheads the rest of the time and they readily hit both lure types in any shape or color.

 

I do know that I caught more in spring and fall, even though I caught some in the summer, and that evening fishing was better than daytime, even though I caught daytime fish as well. I never used any type of live bait but I know that many walleye fishermen use bait or tip a lure with a piece of live bait.

 

I don't know if you can apply any of my experience to your weedy lake, but good luck.

Just like with any fish, there is no one best time, best lure, best color or best pattern to catch a walleye. One day, a particular lure in a particular color at a particular time will just kill them. Tomorrow, it can all change. That's why fishermen have big tackle boxes. Better fishermen have bigger tackle boxes. There are just too many variables to say one is best. Probably the most commonly used lure is a jig and minnow, fished during low light conditions. They could be in shallow weeds, deep rock humps or somewhere in between. That's the part you have to figure out on your own.
