I have been fishing Osborne for more than 25 years and there are still times I can go out there and get skunked.
-I would concentrate in the evening, between 4pm and dark.
-You will be hard pressed to find any place to fish from the shore once you get south of Lantana road, unless you trespass in someones back yard.
-The main lake, off lake worth road where the boat ramp is, is starting to develope grass along the edges. Like I said before, I would concentrate in the NE section of the main lake. In this area, throw a rattle trap, pointer minnow, senko or 6-7 inch black worm. Here's a tip- use the lightest line possible with your soft plastics.
-The next body of water south of the main lake is known as church lake, because of the church next to it, DOH. I don't care for this part of Osborne but it has the most area to fish from shore. Your max depth around this part of the lake is about 9-10 feet and 2-5 or 6 feet around the edges.
- If you continue south from there, along the roadway on the east side of the lake, you'll see a big grassy island in the middle of the lake. Stand on the east shore and cast towards the west to the island. Use rattle traps or topwater. There is a bunch of sht grass on the bottom in sporadic areas so start reeling your trap as soon as it hits the water, You'll get a sht load of snot grass if you try bouncing it on the bottom, but there's bass in this area.
-Next stop will be Lantana bridge. Walk down to the waters edge from the bridge and fish cranks, worms or traps. Fish the NE, NW, SE and SW sides of the bridge.
-Another tip- If you fish worms or senkos, make sure you fish them SLOW and use light line (6-8 pound test). You won't need much weight because Osborne is a shallow lake. Average depth is 5-7'. I don't use more than 1/8 ounce weight.
That about covers everything so don't ask me again until you go out there and try it a few times. Good Luck.
P.S. If you see the illegal immigrants usning a cast net, make sure you kick'em in the ars.
