After a wet July, portions of the District left abnormally dry


While some areas in the central and northern region of the St. Johns River Water Management District received more than 10 inches of rain, portions of the District, including parts of Brevard and Osceola counties, were left abnormally dry as reported in the U.S. Drought Monitor.

A full report outlining July hydrologic conditions was presented at the District’s Governing Board meeting Tuesday. Highlights include:


  • Districtwide, July rainfall averaged 7.02 inches, which is 0.18 inches above the average for the month.
  • Nassau County had the most rainfall, with a countywide average of 9.1 inches.
  • Brevard County received the least amount of rainfall at only 4.9 inches.
  • Districtwide, the cumulative rainfall total for the past 12 months is 49.53 inches, which is 1.48 inches below the long-term average.


  • Upper Floridan aquifer conditions (groundwater levels) at the end of July were mostly in the normal range across the District, except for eastern Duval and northern St. Johns counties, where conditions were in the low or very low range.
  • Groundwater levels expressed as a single Districtwide index are at the 65th percentile Districtwide. This means that since 1980, aquifer levels have been higher than they currently are about 35 percent of the time. 

Spring flows

  • The mean monthly flow at Silver Springs decreased to 593 cubic feet per second (cfs), or 383 mgd, which is a 25 cfs decrease from June’s mean, but still in the normal range for this time of year.
  • At the Blue Spring station in Volusia County, the mean monthly flow was 145 cfs, or 94 mgd.
  • At Rock Springs, the monthly mean flow increased 1 cfs to 58 cfs (38mgd), which is in the normal range for July.
  • Mean monthly flow at Wekiwa Springs decreased to 69 cfs (45 mgd), which is in the high range for the time of year.

    Apopka sure is getting famous....at night, I'm usually watching Monster quest on the Quest network, and doing something else, but half listening. The other night, the program was all about the invasive dangerous pythons, and they started talking about one of the biggest ones ever, and then they pinpointed Apopka, FL. on the map, and zoomed in, and I was like, OMG, No!!! It was one kept as a pet, in a chain link kennel in a backyard on Lake Apopka. 20 feet long, over 300 lbs. and would woof down seven live rabbits per meal, oh, and had escaped at least twice! My worst kind of a nightmare. Tonight, I was half listening again to the program, and they told of a man with snorkeling goggles on, exploring underwater in very clear water, and a 6 foot gator popped him in his back, took him down, until he saw a bunch of bubbles, and the gator's white belly, and he bit him in the back of the head, and had to go to the hospital, and get his head stapled up....Kelly Park swimming area!!! I didn't hear of that before. The guy's name was Michael Diaz, and it was in June 2006. I looked it up. Very freaky watching Monster quest, when I would expect monsters around the globe, and they keep bringing up Apopka, FL. !!!!!
