Group: Save Eastern Lake
Walton on tap to restore coastal dune lake
By HEATHER CIVIL heatherc@nwfdailynews.com

SEAGROVE BEACH — Walton County is taking steps to restore Eastern Lake, but the effort cannot happen soon enough for some. Members of the Eastern Lake Neighborhood Association want to make sure the county is doing all it can to help save the rare coastal dune lake.
The group has sent a petition to the county with about 300 signatures on it from residents and property owners who say the lake needs human intervention to restore water quality and preserve the lake’s aquatic life. The lake is facing two problems. One is overgrowth of ditch weed in the water, which scientists say is a result of the ongoing drought.
The other is the partly man-made problem of sand buildup. “The lake’s been stopped up for two years,” said ELNA member Bill Mancil.
Sand trouble
Eastern Lake is one of 11 coastal dune lakes that are found almost exclusively in South Walton County. The lakes periodically open to the Gulf of Mexico, creating an estuary that mixes salt water with fresh water, resulting in a unique aquatic environment. Eastern Lake has historically opened to the gulf when the water level in the lake reaches a high-enough point. But sand blown into to the lake during Hurricane Dennis has blocked the lake from outflowing as it should.
****Some of the sand now piled up on the bottom of the lake was just beach sand. Some of the sand was put on the beach by Dallas-based property owner Worth Williams, who wanted to create larger sand dunes next to his property.
****Mancil said Eastern Lake has not opened naturally to the gulf since the hurricane.
****“I’m not sure we’ll live long enough for that sand to be pushed (out naturally),” he said.
****Mancil and other ELNA members concerned for the health of Eastern Lake have been pressuring the county to remove the excess sand.
****The county plans to dredge the sand from the lake.
****However, whether the work gets done hinges on several property owners who live adjacent to the lake.
****Before the county can get a state Department of Environmental Protection permit to dredge Eastern Lake, the county must get permission from the owners to use portions of their property for the project.
****Officials are discussing the matter with the property owners, but it is unclear how long it could take to get their permission.
****In the meantime, the county is seeking an emergency permit from the DEP to use equipment to dig out the outfall and help Eastern Lake flow into the gulf. There is no timeframe for that yet.
****Water weeds
****Mancil and others believe the sand in Eastern Lake is contributing to an overgrowth of ditch weed.
****The plant matter can be seen carpeting the lake just beneath the water’s surface.
****But scientists are not convinced the sand is the root of the weed problem.
****As of yet, there has been no direct evidence that the excess sand in Eastern Lake has caused any permanent damage to the water or its aquatic life, said Julie Terrell, biologist with the Choctawhatchee Basin Alliance.
****Studies to determine the overall health of the lake are under way.
****The CBA, the DEP and the University of Florida are gathering data that will reveal how Eastern Lake has functioned historically, but that information is not yet available, Terrell said.
****“I don’t have clear data on that,” she said.
****The plant overgrowth likely stems from a lack of rain, and not from the buildup of sand, Terrell said.
****The water in Eastern Lake is normally a brownish-black color resulting from tannic acids that are washed into the lake from surrounding plant life.
****The lack of rain for the past several months means the acids are not washing into the lake. During the past several months of drought, the lake water has cleared, Terrell said.
****Clearer water allows the sunlight to penetrate deeper into the water. The weeds are thriving off the extra light, Terrell said.
****“We’ve had very clear water, which is, in my scientific opinion, what’s contributed to the plant growth there,” Terrell said.
****That situation can be resolved only when rain starts coming again, she said.
****The weeds should die off, and the lake will recover once there’s enough rain, she said.
****“We’ve got a lot more sunlight entering that system (than usual),” she said.

(I've been working with the University of Florida and the Choctawhatchee Basin Alliance, studying the Lakes during the last two years, so I speak with a little bit of knowledge on this subject.)

Finally, an article with scientific balance. By the way, the only evidence of Eastern Lake water quality given by the homeowners around Eastern Lake is that their docks get underwater. Frankly, that isn't much reason at all to open the lake. I believe the costs to open the Lake the last time they did it was around $75,000 .

I have been watching the Coastal Lakes for some time now, and the "problems" with Eastern Lake exists on all but two of the other Coastal Lakes in Walton County, and this was recently confirmed by another involved and caring local who knows quite a bit about the enviroment. Granted, Worth Williams added sand which should have never been allowed in my opinion and this contributed to some blockage of the Lake. However, Eastern Lake is not different from the other Lakes in it's recent lack of opening. With most of the Lakes, the inflow of salt water doesn't occur until we are hit with large storms. The Lake elevations are probably 6-10 ft higher than the Gulf, so the inflow just doesn't happen too often. The outflow of the Lakes will happen more frequently, but rain is needed to do that. I guess the Eastern Lake property owners have their heads so deeply buried under Worth Williams' sand that they do not see that the other Lakes have not had the exchange in the recent two years.

The Ditch Weed is growing like mad in the other Coastal Lakes, and I can verify with scientific data which I've been collecting, that as Terrell stated, due to the drought, the water clarity has changed, allowing the Ditch Weed to thrive. Water visibility has increased from 3' to depths of 6-8 ft, and in most of the Lakes, the depths will average around 8 ft, so light is getting to the bottom of the Lakes.

Oyster Lake is dying too...but it's problem is a man made cement girder....i wish the state would acknowledge how precious these lakes are...AND DO SOMETHING!!!

What is the difference between a dying lake, and a lake that is different than it has been in the previous x number of years. I haven't heard any discussions of things actually dying, but plenty of discussions on how things are different. Are there fish kills and toxic algal blooms? I guess I am just curious on a definition of dying in this case.

Also, how long have people been around these lakes to be able to say what has changed? I thought it was less than 100 years. Needless to say, I am glad CBA is looking into the changes to try and determine what is happening and why.

The cement girder is only a small part of the problem with Oyster Lake. The real problem is that 30A cuts off the Lake from the beach.

There was also a thoughtful letter to the editor in the 6/16 Walton Sun.

To SJ's point, I've wondered if the other lakes were in similar condition. Eastern Lake can easily gain more attention due to having a neighborhood association and probably the most lake-front houses.

But not to take anything away from the rest of them, I'd hope the current swell of attention helps to create an improved scientific understanding of all the lakes. And then a resolution of the Worth Williams-caused problems, preferably without enriching him as a reward for creating the problem in the first place.

FYI - for anyone who wants to see them, I do have photos taken on Sept 01, 2005 of the County opening Eastern Lake, along with Worth Williams creamy colored sand dune in the background. There is nothing natural about the method the County uses to open the Lake, nor does the opening cause the water from the Gulf to come rushing into the Lake. I was disappointed to read another letter to the editor of the Walton Sun in yesterday's paper, in favor of "returning the Lake to it's natural state." If we did that, all of the houses around the Lake, and their grassy lawns, would need to be removed and replanted with shrub.

On a side note...my boys caught some great fish from Eastern Lake 3 weeks ago! I will see if my hubby will post pix. They were quiet large and were caught while casting from the sand. It is an amazing place!
We have made some priceless family memories there over the past few years ( as I am sure other folks have done forever) We need to do all we can to keep our world healthy! Many thanks to those who are actively working to do so!!
