RE: April 2026 Hydrologic Conditions Report

RAINFALL

  • Districtwide average rainfall for the month was 0.88”, which was about 74 percent lower than the 1932-2025 average of 3.38” (Table 1, Figure 1). The 12-month period ending April 30 reflected a Districtwide rainfall deficit of 20.22”, which was an increase to the 19.98” deficit seen at the end of March. District counties ranged from just over 0.5” to 1.4” of rainfall on average, with parts of Taylor, Suwannee, Columbia, Hamilton, Union, Gilchrist, and Dixie counties receiving more than 2.5 inches of rainfall (Figure 2).
  • Overall, a 12-month rainfall deficit was present in all river basins, with the Aucilla and Coastal basins increasing in deficit by the end of April (Figure 3). A small area in the southern Waccasassa Basin showed a deficit of less than 8 inches. Portions with deficits greater than 29” were also observed in the Aucilla, Santa Fe, and Suwannee basins. Each river basin increased its 3-month rainfall deficit by the end of April (Figure 4). No surpluses were seen over the past 3 months, and each river basin had areas measuring anywhere from less than 6” to more than 9” of deficit. Sections with greater than 9” of rainfall deficit can be seen in all 5 of the basins.
