Retention pits. Not all of them are created equal.

Down here in my area, the retention pits are actually fill pits to build up housing properties. There are also the smaller retention pits that are primarily flood runoff for large highways like the turnpike. Generally, these are both sprayed to control hydrilla growth. At times, this can be a good thing as well as a bad thing.

When they don't spray and the grass mats up, you can really start to nail fish punching through the mats. Generally, you'll need heavier gear for that than a small MH, though. You can get by with a heavier MH flippin stick. Those generally have a little more backbone. Down here in southern Florida, heavier gear is generally a necessity from what I've found. You're going to deal with heavy grass in most of the lakes and unmanaged retention pits. You can use the lighter rod if you selectively pitch to open spots in the grass, but be ready to really move the fish if you get bit on lighter tackle.

As far as there being no structure on your pond; there is always structure of some kind. It may be a single rock, a deep drop off, or a very defined weed edge. My lake is very similar to that. It's got grass in some sections, but for the most part it's a very sharp drop off around the entire lake. What you need to find are those irregularities on the structure of the lake. Those should be the hot spots where you'll find fish.

As far as lures go:

It's hard to beat the Senko like Evrgladesbasser mentioned. Those will always produce fish down here.  Rig it Texas style with no weight, just toss it out and let it fall.  You should be able to cast it weightless on your MH rod.  A 5" Senko alone weighs around 3/8 oz.  Most people don't realize that they're actually that heavy.  Throw in your hook and you have close to a half ounce lure that falls very slowly and naturally in the water.

Any Texas rigged worm or other soft plastic bait will work. Rig it weedless, toss it out and work it back to you. http://www.bassresource.com/beginner/worm_fishing.html Big worms are an old Florida favorite for most people.

Topwaters of almost any kind. Buzzbaits if you've got a little less stuff on the surface to get hung on. Otherwise, some kind of frog. Be it a soft plastic buzz frog (horny toad, rage toad, etc etc), or something like a Spro hollow bodied frog.

Lipless crankbaits burned over the grass, or ripped free from the grass will also produced at certain times. Try hard to match the size and shape of the forage in the lake (if you know it). Bring it back with some erratic movements and hold on.

As far as gear goes:

You can for the most part get away with a decent baitcaster and a medium heavy rod. If you start getting into really thick stuff, a heavy or extra heavy may be needed. I've got every rod I have spooled with braid, save one (my cranking rod). 30-50 pound is fine for most applications, again if you're getting into really heavy cover, you may want to bump it up. The brute strength of braid, combined with the sensitivity makes hauling fish out of thicker grass much easier.

Dont worry about expensive equipment out of the chute....Just get a MH rod, Shimano reel, 30lb braid, and learn to fish plastics by going out fishin, preferably with someone with a bit of experience....It will all come to you in short order, then expand lure choices.....Have at it!..... 8-)

You came to the right forum! These folks know the in's and out's of Bass Fishing...Welcome!!!

I have 30 lb test braid and the other day u was fishin with a couple buddies of mine while we were camping and caught my first bass on a Texas rigged senko it was a tiny bass probably like a half lb but I was fricken stoked hahahaha thanks for all of your help I have learned so much from all of you

I have pfleguer president reel is shimano better than that? And also I think I got some attractant in my reel and now my reels kinda sticky how can I fix this?
