Rolling sand hills are not what most people picture in Florida, but Clermont sits on the northern end of the Lake Wales Ridge, where early settlers called the terrain the High Sand Hills. Below those slopes lies the Clermont Chain of Lakes, a string of tea-colored lakes including Minneola, Minnehaha and Louisa that forms part of the headwaters of the Ocklawaha River. Hills and lakes together shape how water moves through the city: fast down the slopes, then slowly through the chain.

Milton's Overnight Rain in South Lake
Hurricane Milton made landfall near Siesta Key on the evening of October 9, 2024, and its worst effects reached South Lake around 2 a.m. the next morning. The South Lake Tablet reported an estimated 13 inches of rain in 24 hours, along with wind the area had not felt since the 2004 hurricane season. Residents of the Emerald Lakes mobile home community on State Road 50 waded through knee- to waist-deep water to evacuate. A failed storm drain behind a business on East SR-50 opened a 40- to 60-foot erosion hole, part of a trail near Hiawatha Park collapsed, the Johns Lake system overflowed, and the city's docks on Lake Minneola were heavily damaged.
That mix of flooding in low spots, erosion and wind damage is typical of how a big storm plays out on this terrain. A provider handling storm damage cleanup will normally tarp roof openings, remove soaked insulation and ceiling board, and dry the structure before rebuilding starts.
Runoff on the Ridge: Hills, Sand and Low Lots
On flatter ground, rainwater spreads out. Here, slopes concentrate it. Homes built at the bottom of a grade, or on lots cut into a hillside, can receive runoff from streets and neighboring yards during a heavy storm. Sandy soil absorbs a lot of water until it is saturated, after which the excess runs fast and can scour around foundations and driveways.
- Check where gutters discharge; downspouts dumping against a slab on the uphill side can push water under doors.
- Keep swales and yard drains clear so water has a path around the house.
- Watch for soil washing away beside slabs or pool decks after a storm.
- Look for damp baseboards on uphill walls, which can signal water entering at the slab edge.
A Fast-Growing City of Newer Homes
Clermont's population grew from about 9,300 in 2000 to more than 43,000 by 2020, with estimates topping 52,000 in 2025. Much of the housing is therefore recent, and newer homes have their own water-damage patterns. Plastic supply lines to toilets, sinks and refrigerators, washing machine hoses, and attic air handlers with condensate drains are the usual suspects. A water heater in the garage that fails overnight can soak the adjoining laundry room and hallway before morning.
Fast action keeps these jobs small. Shutting off the main valve, removing standing water and getting a water damage repair provider to dry and replace damaged materials early can often save cabinetry and flooring that would be lost after several days of soaking.
Lakefront Living and Long Wet Seasons
Clermont averages a little over 50 inches of rain a year, most of it during the summer rainy season, and humidity stays high from late spring into fall. Wet drywall and carpet in that environment can show mold within a couple of days, and closed-up rooms, such as a seasonal home or a guest suite, can develop a musty smell without any visible leak.
If you notice spotting on walls, warped baseboards or a persistent odor, have moisture levels checked. A provider offering mold remediation will typically find the source, contain the affected area and remove damaged porous materials.
After the Water: Practical Steps in South Lake
Before cleanup begins, photograph everything, including the waterline on walls and damaged contents. Contact your insurer early and ask whether the loss falls under homeowners coverage or flood coverage, since rising water from lakes or runoff is usually excluded from standard homeowners policies. Check your property on the FEMA Flood Map Service Center to see whether it sits in a mapped flood zone.

Common Questions
Clermont is on high ground. Why do some homes still flood?
Elevation helps against river flooding, but it does not stop runoff. On hilly terrain, rain collects on slopes and streets and flows toward low lots and lakes. During Milton's roughly 13 inches of rain, low-lying spots such as a mobile home community on State Road 50 flooded badly. Drainage around the individual lot often matters more than the city's overall elevation.
What should I do if my mobile or manufactured home took on water?
Turn off power at the main breaker before entering if water reached outlets or the floor system. Manufactured homes often have insulation and ductwork under the floor, which can hold floodwater out of sight. A restoration provider should check beneath the home as well as inside it. Document damage thoroughly before anything is removed.
Are the Chain of Lakes a flood risk for nearby homes?
The chain drains slowly northward through the Palatlakaha River toward Lake Harris, fed by streams and groundwater from the Green Swamp area. During prolonged heavy rain, lake levels can rise and nearby low areas can stay wet longer. Milton caused Johns Lake to overflow its banks. Check your lot on the FEMA flood map if you live near a lakeshore.
How quickly does mold appear after a leak in Clermont's climate?
In humid summer conditions, mold can begin forming on wet drywall, carpet backing and wood in about a day or two. Speed matters most in the first 48 hours. Removing standing water, running dehumidification and checking moisture inside walls usually prevents a small leak from becoming a larger repair.
