The lakes in the downtown Orlando are part of FWC's Fab Five program (Clear, Ivanhoe, Starke, Turkey, and Underhill).
I can't help with Clear Lake as I no longer fish there after friend's SUV and trailer were vandalized the last time we went. The ramp and dock are in a bad section of town. FWC has actually removed the fish feeders as angler's weren't using them. Any guesses why?
Ivanhoe is a good lake that sees quite a bit of fishing pressure on the weekends. Weekdays there is hardly anyone there. The ramp is on the east side of the eastern lobe of the lake. However, there are parking spots on the west side (I-4 divides the lake east and west) on the perimeter road as it approaches towards I-4. If you use hardbaits like a jerkbait, throw something you wouldn't mind losing. Ivanhoe has a very health population of chain pickerel and gar.
Starke is still dealing with a bad algae issue that is causing the water to be green. It is getting better, but until it is resolved, not a lake I frequent. The last 2 years, FWC haven't hit their fishing numbers on this lake because of the water quality issues.
Turkey is probably the hidden gem of smaller lakes. Yes, Lake Toho, Lake Kissimmee, and Lake Okeechobee hold the giants, but Turkey Lake is the giant keeper of the Fab Five program. It is a boat deed restricted catch and release lake for bass, so you won't be able to bring your own kayak or boat. If you do, the penalties are the same as if you were poaching. However, the city of Orlando runs a boat rental program for around $30 for 4 hours of fishing in the mornings (7AM-11AM) Thursday-Sunday. This time of year, you can call a day or two in advance and get a spot. The lake has been set up by FWC for a fishing quota of 1 fish for every 2 man hours spent fishing. I've always surpassed the quota. They just recently started a kayak and canoe rental program, but don't have any details on it. If you call for info or to rent, be persistent as the entry gate handles the boat rentals, campsite reservations, and park entry.
Underhill is the other catch and release lake in the Fab Five. There is no boat restriction on this lake. The lake almost always has a couple boats on it every day of the week, and sees lots of boat traffic (fishing and waterskiing) on the weekends. I am catching less fish at this lake than I have in years past. Since it is a catch and release for bass, it isn't restocked like Ivanhoe, Starke, and Clear Lake are with bass. Part of the issue have been from an otter and large gator (probably both since removed as I haven't seen either in a while), but not before they along with people not abiding by catch and release have done a number on the bass population. I wouldn't be surprised when FWC does their next survey of the lake to see the numbers down and a potential re-stock in the future. FWC has stepped up the law enforcement patrols here, and last time I was out, had signs warning about poaching.
Hope this helps and good luck!!!
