June Rainfall Nearly Double District-wide Average.
Water Conservation Areas received more than twice their monthly average rainfall, leading SFWMD, DEP, and USACE to take measures to address high water emergency.
The South Florida Water Management District issued the following news release.
‘These two extremes illustrate the system’s unpredictability and showcase the alertness required to take necessary actions when drought concerns turn to flooding realities,’ said SFWMD Governing Board Chairman Dan O’Keefe. ‘This is the nature of water management in South Florida and this is why we work 24/7 to protect families, businesses and the environment.’
The District-wide average rainfall for June was nearly 15 inches or about 181 percent of average. The three water conservation areas, critical links in the system, which convey water south from Lake Okeechobee to Everglades National Park, received the heaviest rainfall. Water Conservation Areas 1 and 2 received 18.49 inches or 246 percent of average. Water Conservation Area 3 received 18.74 inches or 219 percent of average.
- Implementing emergency deviations with the approval of the U.S. Army Corps of Engineers to send more water to tide using the S-197 structure in Miami-Dade County, as well as increasing pumping at the S-332D pump station and allowing the use of the S-343A and B and S-344 structures to move more water out of the conservation areas to Everglades National Park and the Big Cypress National Preserve.
- Maximizing discharges from Water Conservation Area 1 to tide through the Hillsboro Canal in Palm Beach County.
