Lake Juliana anchors Auburndale's north-side lake country between town and I-4 — and unusually for Polk County it drains toward the Withlacoochee River watershed rather than the Peace. Its giant neighbor Lake Mattie sits immediately east: about 1,100 acres with no documented navigable connection to Juliana and, as of July 2026, no public boat ramp anywhere on it — which makes Juliana's county ramp the closest public launch to both lakes.
A fertile, eutrophic lake (Water Atlas trophic index 63) that fishes like classic Central Florida: bass push shallow through the winter and early spring, specks stack in the cool months, and bluegill and shellcracker carry the warm half of the year. The June 2026 chlorophyll reading of 28 µg/L sat right at the lake's long-term average — green, fertile, normal. Summer play is dawn and dusk, and Juliana is one of the few lakes around where dawn can legally start at 4 a.m.: FWC lists the county ramp as open 24 hours (the county's blanket parks line says 6 a.m.–10 p.m. — see the ramp page for how to read that). This is also water-ski country: USA Water Ski & Wake Sports runs its national headquarters from the Lake Myrtle sports complex next door, so expect recreational traffic on summer weekends.
Plain English Summary
| Ramp hours | FWC's inventory lists the Lake Juliana ramp as open 24 hours; Polk County's blanket parks page says boat-ramp hours are 6 a.m.–10 p.m. The county explicitly allows after-hours launching at several of its ramps, so treat the FWC per-ramp listing as the specific one — and follow anything posted on site. |
| Fees | No launch fee — the county ramp is free (FWC inventory, status Open for Business as of July 2026). |
| Boating restrictions | No FWC boating-restricted areas are on the books for Polk County waters in chapter 68D-24; any local no-wake zones would be city or county ordinance, so honor posted buoys and signage. |
| Fish consumption | Lake Juliana is listed in the Florida DOH 2021 mercury guide (black crappie, bluegill, largemouth bass, redear). Limits vary by species and population — check the current DOH guide rather than a summary. |

Auburndale keeps its big water on the north side of town, where the lakes drain — unusually for Polk County — toward the Withlacoochee rather than the Peace. Lake Juliana is the flagship: roughly 930 acres, green and fertile at a trophic index of 63, with the Lake Juliana Landings community and its private marina on the shore. This is water-ski country in the most literal sense — USA Water Ski & Wake Sports runs its national headquarters from the Lake Myrtle sports complex next door — and the county's ramp page calls the lake 'filled with bass, bluegill, shellcracker and specks.'
The ramp is the practical story: free, concrete, one lane at 500 James Place, listed 24 hours by FWC — the county's blanket parks line says 6 a.m.–10 p.m., so treat posted signage as final. The county lists an aluminum dock; FWC's inventory shows none — treat the dock as probable rather than promised. Be on the water before the ski boats wake up: dawn bass on the fertile flats, bluegill and shellcracker once the sun climbs, and a speck rig in the rod box from Thanksgiving to Easter. Looming just east is the lake you can't launch on — Lake Mattie, about 1,100 acres with no public ramp anywhere as of July 2026.
