Putnam County Florida map readers can organize the county around Palatka and the St. Johns River, then extend outward to Interlachen in the west and Crescent City, Pomona Park, and Welaka in the south. Settlements are separated by lakes, forest, and wetlands, so the waterways and highway corridors matter as much as the place labels.

Government and the largest urban concentration sit in the Palatka area, but most of the county consists of low-density communities, small lakes, and unincorporated land. The 2020 density of 100.7 residents per square mile explains why large spaces appear between town labels.
What the Map Shows
Palatka occupies the west bank of the St. Johns River in northeastern Putnam, opposite East Palatka. County offices and several state routes converge there, making it the most effective starting point for interpreting directions to the county’s smaller communities.
Interlachen lies west of Palatka along SR 20. Hollister falls between the two, while Florahome and the Putnam portion of Melrose are farther northwest. This sequence clarifies the western interior, where scattered lakes can otherwise make the settlement pattern look disconnected.
US 17 strings together Satsuma, Pomona Park, and Crescent City in the south. Welaka and Georgetown occupy a separate line along CR 309 on the west bank of the St. Johns, so the Crescent Lake highway corridor should not be confused with the riverbank corridor.
Putnam borders Clay to the north, St. Johns to the northeast, Flagler to the east, Volusia to the southeast, Marion to the southwest, Alachua to the west, and Bradford to the northwest. Despite lying between coastal counties, Putnam itself is inland and has no Atlantic shoreline.
County Layout and Location
US 17 is the principal north–south line on the eastern side. South of Palatka it connects Satsuma, Pomona Park, and Crescent City; northward it feeds into the lower St. Johns and Jacksonville road network.
SR 20 extends west from Palatka through Hollister and Interlachen toward Gainesville. East of downtown it crosses the river to East Palatka, combining the county’s main inland east–west route with one of its limited river crossings.
SR 19 runs southwest from Palatka past the Rodman Reservoir and Cross Florida Barge Canal area toward Marion County. SR 100 connects Palatka with Flagler County and Bunnell to the east, while SR 207 leaves East Palatka toward St. Augustine in the northeast.
Together, these routes establish Palatka as a junction rather than merely a river town: SR 20 points west, SR 19 southwest, US 17 south, SR 100 east, and SR 207 northeast. Welaka sits away from this state-highway fan, so CR 309 must be identified separately for access along the southern riverbank.
Local Context
The St. Johns begins in southeastern Florida and flows north. Putnam marks the start of its lower basin, which continues to the river mouth in Duval County. Near Palatka the broad channel and limited crossings make bridge locations and roads on each bank especially important.
The Ocklawaha approaches from the southwest and enters the St. Johns south of Welaka. Rodman Reservoir occupies the Ocklawaha system west of SR 19, linking the county’s southwestern reservoir landscape with the river junction near Welaka.
Crescent Lake is the large water body in southeastern Putnam. Dunns Creek runs roughly six miles between the lake and the St. Johns, which means Crescent City is a lakeside community connected hydrologically to the main river but is not located directly on the St. Johns channel.
Sandhills, pine flatwoods, and wetlands occur around Dunns Creek, while many small lakes punctuate the Interlachen side of the county. A county-scale reference graphic is suitable for the relationship among major waters and roads; wetland limits, parcel access, and minor lanes require current Putnam County GIS data.
Ways to Use This Map
- Place the communities: Set Palatka as the anchor, then locate Interlachen west, Crescent City south, and Welaka southeast on the river.
- Read the road system: Find US 17 and SR 20 first, then compare the directions taken by SR 19, SR 100, and SR 207 from the Palatka area.
- Trace the waters: Follow Dunns Creek from Crescent Lake to the St. Johns and locate the Ocklawaha confluence south of Welaka.
- Continue across boundaries: Pair eastbound routes with Flagler or St. Johns maps, southwest routes with Marion, and westbound routes with Alachua.

Frequently Asked Questions
What is the county seat of Putnam County?
Palatka is the county seat. It stands on the west bank of the St. Johns River and combines the county-government role with the county’s most important highway junction.
How does Crescent Lake connect to the St. Johns River?
Dunns Creek leaves the north side of Crescent Lake and travels about six miles to the St. Johns. On the map, the narrow creek between the large lake and main river establishes the connection.
Are Welaka and Crescent City on the same highway corridor?
No. Crescent City is on US 17 beside Crescent Lake, while Welaka lies farther east on the St. Johns River and is reached by CR 309. Their apparent proximity does not translate into one direct highway line.
Which roads lead from Palatka to Interlachen and Crescent City?
SR 20 is the basic route toward Interlachen, and US 17 is the basic route toward Crescent City. Because they leave the Palatka area in different directions, identify the route number before tracing the destination.
