Mud Lake — Polk County and the Water Atlas both spell it 'Mudd' — lies just west of Polk City off State Road 33, in the Withlacoochee watershed at the edge of Green Swamp country. No navigable connection is documented, so treat it as landlocked. The lake runs elongated north–south, with the county ramp at its north end on the highway. Florida reuses the name Mud Lake all over the state — make sure this Polk County one is the lake you mean.
Crappie seasons rule a lake like this: the cool months are the show, and the county explicitly allows after-hours launching, which puts the pre-dawn speck bite in reach. It's shallow — the Water Atlas gives a 3-foot mean — so by high summer, heat and vegetation own most of the bowl and dawn is the only sensible window. The water runs fertile and green: the lake's state water-quality file carries impairment listings for biology, chlorophyll-a, nitrogen and phosphorus. No DOH consumption listing names this lake in the 2021 guide. As of July 2026 the ramp is FWC 'Open for Business,' with 'Needs Repair' noted on both the ramp and the parking area (the survey's date isn't published).
Plain English Summary
| Ramp hours | 5 a.m.–10 p.m. per FWC's inventory — and the county's own page adds that 'boat launching and retrieval [are] available after hours.' The blanket county parks line (6 a.m.–10 p.m.) is the loosest of the three; follow posted signage. |
| Fees | No launch fee — free county ramp (FWC inventory, Open for Business as of July 2026). |
| Ramp condition | Concrete, but FWC's survey rates both the ramp and the gravel parking 'Needs Repair' (survey date not published). Expect worn edges and pick your line. |
| Boating restrictions | No FWC boating-restricted areas are on the books for Polk County waters in chapter 68D-24. A 3-foot-mean lake enforces its own speed limit. |

Is it Mud Lake or Mudd Lake?
Which Mud Lake is this? Florida seems to have a dozen.
Is the ramp actually usable?
Can I launch before dawn?
How shallow is it, really?
What's worth catching?
Mud Lake — 'Mudd' with two Ds on Polk County's own ramp page and in the Water Atlas, 'Mud' to the federal gazetteer and FWC — is 160 acres of shallow, fertile water stretched north–south along State Road 33 just west of Polk City, out where the plateau starts dissolving into Green Swamp country. Mean depth is about 3 feet, the water runs green and fertile, and the county ramp at the north end is worn concrete with 'Needs Repair' noted in FWC's survey. This is jon-boat water for people who know exactly why they're here.
The county's pitch names black crappie and bass, and adds the line that matters: 'Boat launching and retrieval available after hours.' Shallow, fertile bowls are speck factories in the cool months, and a county that blesses pre-dawn launching has endorsed the way this lake actually gets fished — dark-thirty, jon boat, minnows, four gravel trailer spots that were never going to fill anyway. Bring the jon boat, not the glitter rig; ease down the worn concrete (the edges are the rough part) and drift the middle with minnows from Thanksgiving through the spawn. Skip high summer, when three feet of green water and July heat argue with each other all day. If the morning leaves you wanting bigger water, Lake Juliana's 24-hour ramp is five miles south — a different lake in every sense.
