On Friday, July 18th, Dr Gary Goforth (http://garygoforth.net/resume.htm) and I met at Indian River State College just after noon. I jumped in his truck, wearing my dress and heels, and we drove the back roads to find our destination. Our destination was long time Martin grove, Caulkins Citrus, located off Citrus Boulvard, near Indiantown, adjacent to the C-44 canal which of course connects to the St Lucie River/IRL and to Lake Okeechobee.

Kevin Powers, of the South Florida Water Management District governing board, longtime Martin County resident, and family friend, had invited Gary and I to see a pilot project of “water farming.” Water farming is idea that has been in the works for the past few years and is now finding its reality. If it works, thousands of acre feet of polluted water along the C-44 canal, in this case, will not find its way to the St Lucie River/ Indian River Lagoon. Farmers are paid for this service and their lands are not sold to development.

How could this be? Farmers “growing” water?

First we have to go back a bit.

In a Stuart News article dated April of 2013, Doug Bournique, executive vice president of the Indian River Citrus League, is interviewed by reporter Paul Ivice. Ivice writes:

“Diseases, (greening and canker), hurricanes and urban expansion have all cut into Florida’s citrus acreage which is down 38% from 1996…Nowhere in Florida has acreage fallen as sharply as in Martin County. It has less than 15% remaining of the 48,221 acres in production in 1994. The county has suffered the greatest loss for four consecutive years and and been declining sine 1994.”

As the citrus industry is dying, so is our economy. While farmers figure out what else they can grown on their land, the idea for some farmers to hold precious fresh, all be it polluted, waters on their lands came into being. This helps the river and it helps the farmers and it helps our local economy. Boyd Gunsalus, among other scientist at the SFWMD, has worked long and hard for the past many years on this concept.

Caulkins Citrus is in a prime location and were one of the farms that competed for a bid to try out the new technology and receive a DEP/SFWMD grant.

An example from Google Maps showing C-44's close proximity to Citrus Blvd. Hwy. 76 is south of canal and Citrus is north.

When Gary and I arrived we were met by Tom Kenny, Kevin Powers, and Ronnie Hataway. After introductions, they explained to us how the “farm”operated, how it was created, their hopes for the future, and gave us a walking and driving tour. It was pretty amazing if not surreal. Egrets and herons perched in the dying orange trees surrounded by water. A deer track was at my feet. Water was everywhere and from what I was told could one day go to the horizon.

Although Gary and I had been somewhat skeptical, we left feeling very hopeful and impressed.

So how did they create it?

Basically the grove is fallow due to poor health, and although the farm is much larger, (thousands of acres) a  berm was constructed around a few hundred acres of the grove for the pilot study. Then water was/is pumped from the C-44 canal into the old grove. The berm holds the water inside.

The water can go as high as four feet but according to Mr Kenny it is percolating so well through the soft sandy soils that basically the pump can stay on all the time. The nitrogen and phosphorus and other pollutants are cleaned and eaten by healthy bacteria as the water filters through the earth.

The pilot’s long term goal is to hold 6600 acre feet of water but things are looking like they will be able to hold more. The water is slowly filtered into the water table replenishing the aquifer about 40 feet below. Caulkins is installing a number of apparatuses that they call “wells” that will read where the water is going and what is happening underground. If things work out, Caulkin’s acreage to hold water will be expanded.

Although this is wonderful, we must note that it would take many water farms to offset the water flowing into the SLR/IRL.

Dr Goforth states in a recent writing: “For the 34 days between June 13 and July 17, approximately 51,000 acre feet of C-44 runoff was sent to the St Lucie River…”

With that in mind, if a water farm similar to Caulkins could hold 10,000 acre feet, we would need five just to hold the water that has come in this summer SO FAR from C-44 basin runoff. Of course in time, 2020 maybe, the C-44 Storm Water Treatment and Reservoir and Storm Water Treatment Area will be one line, and hopefully working, and that is said to hold  about 56,000 acre feet. (http://www.tmba.tv/broadcastanimation/everglades-restoration/everglades-restoration/)

In the end, really though, no one knows how much water can be held until these projects are working. Hopefully all of them, like Caulkins Grove seems to be so far, will exceed expectations. 

As we tied up our tour, shook hands and left the property Mr Hataway said, “I have been telling them for years to keep this fresh water on the land….”

Mr Kenny noted, “The goal is to have less water going into the river and out the inlet…”

It is an ironic twist of fate. We worked for 100 years to drain the lands so we could grow agriculture. Now we are trying to keep the water on the land for the health of the river, because fresh water is extremely valuable, and because the citrus industry needs a new crop. 

Words such as these about “keeping the water on the land,” especially from successful agriculturally minded businessmen, are an inspiration to me, and give hope for a better water future.
