Claire, Wisconsin-based bridge builder utilizes the river for the transportation of its finished products. PDM Bridge is notable for the fabrication of the Woodrow Wilson Bridge structure. The Palatka area was of early significance in accessing the interior of the state. This significance was due to its location at the end of an expansive portion of waterway at the divide between the upper and lower St. Johns River. First established as a trading outpost, tourism would eventually boom and fuel growth for decades. The decline of waterborne travel in Northeast Florida, and the United States in general, ultimately reduced the importance of tourism in the city. Nowadays, large international airports and bypassing interstate highways carry vacationers to destinations further south. Only 7.1% of Palatka's labor force works in arts, entertainment, recreation, accommodation, and food services, compared to Florida's 15.5% across tourist related industries. In recent years, the Putnam County government has adopted policies focused on facilitating Ecotourism in the region. Nature trails are being expanded and kayaking waterways have been improved and mapped. Portions of the Florida Trail runs through the area and connect local hiking trails to other trail systems in parks throughout the region. Ocala National Forest is the second largest National Forest in the state. Other large parks include Welaka State Forest, Etoniah Creek State Forest and Dunns Creek State Park. Other conservation areas exist under the management of the Putnam Land Conservancy and St. Johns River Water Management District. Both entities operate regionally and identify and protect ecologically sensitive areas. If progress continues, and ecotourism creates a vibrant local economy, economic incentives could drive further preservation of the natural habitats, benefitting the environment as a whole. Of residents aged 16 years and over, 53.3% were in the labor force; 45.6% were employed and 7.6% unemployed. Compared to Florida's average, Palatka has a higher percentage of unemployed.

The Palatka area is bordered on all sides by four separate metropolitan statistical areas. Of those, the Deltona-Daytona Beach-Ormond Beach, Gainesville, and Jacksonville metropolitan statistical areas all had better performing unemployment statistics than Palatka in 2011, when the unemployment rate in the Palatka Micropolitan Statistical Area was 13.8%. Gainesville showed the most favorable conditions with an unemployment rate of 8.7%.
