LAGOON SYSTEM

Lagoon Lowering Update: April 2025

As many owners are aware, the ongoing bridge project in Leamington requires the lagoon to be lowered beyond its normal levels for extended periods. One of the reasons the water level is much lower than during past repairs is due to the lower clearance of this bridge than other bridges worked on in the past. As a result, you may have noticed increased exposure of the shoreline and lagoon bottom, with some boats temporarily resting along the shore due to reduced water levels. This deeper-than-usual lowering was scheduled to continue on a weekly basis for approximately the next month.

To find a solution that can be beneficial for all parties, we have met with the contractor and Leamington’s representatives and have reached a compromise. The lagoon will be raised to normal levels this weekend and will remain at normal levels for all next week through April 19th, so that many of you and our visitors can enjoy the lagoon during Heritage/Easter week. The lagoon will be lowered to the necessary level to perform the work the following week, April 21 – April 25. The lagoon water levels will return to normal height for the week of April 27 – May 2 and will again be dropped the week of May 4 – May 9. 

The Leamington Bridge project is expected to be completed by May 9. With this work complete, the need for extended lagoon lowerings will come to an end, and water levels will be maintained at their normal height moving forward. As a result, the previously planned May 14 lagoon lowering has been canceled. Routine monthly lagoon lowering will resume on June 11 as scheduled. 

With more debris now visible, PDPOA is taking this opportunity to improve lagoon safety and aesthetics. A professional debris removal service has been on-site daily, working to clear large pieces of wood and other potential hazards that are typically submerged and go unnoticed.

We appreciate your patience and understanding as this important work continues. These efforts are part of our ongoing commitment to maintaining the health, safety, and long-term function of the lagoon system.

Lagoon Water Quality Update and Maintenance Actions: April 2025

The association is aware that some discussion has been circulating amongst the membership with concerns regarding the condition of the water in our lagoon system. We want to assure you that lagoon care remains a priority for PDPOA. Our maintenance staff continues to manage the waterway system with diligence and consistency.

In response to concerns and in line with our proactive maintenance schedule, PDPOA has recently re-engaged a professional vendor—previously used several years ago—to conduct debris and organic matter removal throughout the lagoon system. This service had not been performed in 2024 and is currently underway this week.

Additionally, we coordinated with our water management vendor to take updated water samples at four locations across the lagoon system. These locations were selected to represent a variety of areas within the system:

  • Queens Folly Bridge
  • Carnoustie Bridge
  • Queens Way Bridge (Leamington)
  • Leamington Court

The association is pleased to share that the test results, received today, show excellent water quality across all measured indicators.

Key Results:

Turbidity: Ranged from 1.9 to 2.6 NTU
Interpretation: This is consistent with drinking water standards and typical trout waters (though, of course, lagoon water is not intended for drinking). Lower turbidity indicates high clarity and minimal suspended particles.

Alkalinity: Ranged from 188 to 192 mg/L as CaCO₃
Interpretation: These levels are well-buffered, meaning the water is resistant to sudden pH changes, which helps protect aquatic life.

E. coli & Total Coliforms: Both returned below measurable limits!
Interpretation: This indicates very healthy conditions from a bacterial standpoint.

pH Levels: All readings were at 7.4
Interpretation: This is considered neutral and ideal for water stability.

We are proud of the ongoing work to care for this vital system and will continue to monitor water quality, remove organic debris, and respond to resident concerns. Thank you for your continued engagement and interest in maintaining the health of Palmetto Dunes’ natural resources.

Two freshwater lakes and an 11-mile lagoon system – the second largest in the U.S. – meander through Palmetto Dunes with over 40 species of birds and fish.

One of the goals of the PDPOA and especially the Lagoon & Lake Advisory Group is striving to ensure that the water quality of our lagoon is maintained. Therefore, we test the water at various points to assess the salinity, oxygenation, and the level of fecal matter. The periodic lowering of the lagoon level helps us to improve these areas. We usually lower the lagoon once a month (unless a major storm comes or a need arises, such as the work on Bird Island) to enhance the water quality.

Whether you are a bird watcher, fisherman or boater, your continuing enjoyment requires maintenance of and vigilance over our waterways. Abundant bird life is an excellent indicator of our stewardship of the unique waterways of Palmetto Dunes.

Lagoons are for the pleasure and enjoyment of Palmetto Dunes Property owners. This 11-mile interconnected lagoon system may be used for boating and fishing. Pontoon boats and other small watercraft can be used so long as the propulsion systems are limited to hand powered or electric engines. The PDPOA reserves the right to raise and lower the water level in the lagoons as drainage requirements dictate.

COMMUNITY OBSERVATION DECKS, DOCKS, AND LAUNCHES

There are two community kayak/canoe launches. One is located on the west side of the bridge just after the North Gate on Mooring Buoy in the Mariners section of Palmetto Dunes; the second is located on the east side of St. George to the inside of the small island in the Inverness section of Palmetto Dunes. An observation/fishing deck is located just beyond the Queen’s Folly inbound bridge on the outside of the leisure path.

SWIMMING/PADDLEBOARDS

Swimming and the use of paddleboards is prohibited.

WATERCRAFT: NO-WAKE

Electric boats must be registered with the PDPOA and are subject to size and height limitations promulgated by PDPOA from time to time.

The entire lagoon and freshwater lakes are no-wake zones. Care should be taken to keep engine throttles in the low position in order to preserve our shorelines.

Why Palmetto Dunes is a “No-Wake” Lagoon & Lake System

When an object like a boat moves through the water, it displaces the water creating waves, also known as a wake. The wake is caused by the boat hull pushing the water out of the way. Significant wake is defined as a wake with “white water” immediate to the vessel, in waves created by the hull moving through the water. This requires that all boaters properly regulate and vary their speed based upon boat weight and hull shape so as to minimize erosion of lake banks. Wakes accelerate shoreline erosion, resulting need for costly dredging of the lake bottom and potential lake bank repairs, and can cause damage to wildlife, other boats/kayaks and the people in them.

Because of this, boaters need to understand the impact of excessive wakes to the environment and to our community. The effects of erosion go beyond the loss of property, which includes individual homes’ shorelines as well as common areas that impact the berms, trails, and roads. Wakes lead to increased sedimentation in the lake, which means that expensive dredging will be needed sooner than through natural erosion.

So, what can boaters do to minimize wakes? The solution is simple: Slow down!

When you’re out boating, check your bow wake (wake coming off the front of your boat). If you see white water, you are creating an excessive or prohibited significant wake. Adjust the speed of your boat until your bow wake no longer has any white water, to reduce the effects of wake and wash. Doing so will ensure that you avoid the problems of accelerated shoreline erosion and damage to personal property.

COMMUNITY BOAT RAMP

The Palmetto Dunes community boat ramp is located on the south side of Queen’s Folly Road just beyond the inbound bridge. The boat ramp may only be used by owners of property in Leamington and Palmetto Dunes Resort. Guests, renters, and others are not allowed to use the boat ramp. Property owners must register their boat with the PDPOA and arrange for access to the boat ramp by contacting the PDPOA at 843-785-1120. The boat ramp is intended for launch and retrieval of boats permanently in the lagoon. Daily launches and retrievals are not allowed.

FISHING

Property owners, guests, and renters are allowed to fish in the lagoon and lakes from boats, kayaks, or canoes from the launches and observation decks, and from land in the common areas of Palmetto Dunes and Leamington. Owners of property and their guests with direct access to the lagoon or lakes may also fish from their own property. Fishing from bridges is not allowed due to safety concerns. Fishing from golf course property is not permitted. All fishing is subject to the following requirements:
all people age 16 and older must possess a valid fishing license from the South Carolina Department of Natural Resources, and abide by all state and local fishing regulations; all fishermen shall practice “catch and release” to preserve the fish population
commercial fishing by members or guests is prohibited.

WILDLIFE

Feeding or harassing of wildlife within or upon the lagoon and lake system or any other common property of PDPOA is prohibited.

Discharge, Release or Dumping. The discharge or release or dumping of any substance into the lagoon and lake system which might in any way impair its operation or water quality or endanger the health and welfare of the aquatic life therein is prohibited. Such substances include, without limitation, swimming pool and/or spa water or waste, fertilizers, pesticides, or chemicals; grass clippings; leaves; pine straw and/or other landscape bedding material.

TREES AND BUSHES

Property owners are responsible to keep bushes and trees from hanging into the lagoon and lake system and must remove any that fall therein.

DOCKS, RAMPS AND BULKHEADS

All docks, ramps and bulkheads shall be maintained in good repair to prevent any unsightly, unclean, unsafe or unkempt condition.

The Palmetto Dunes Property Owners Association takes very seriously its role in preserving and protecting the quality of our waterways. For more information regarding these Regulations and policies and procedures of the lagoon and lake system, reference is made to the Lagoon PP&G.

PROTECTING WATER QUALITY

Palmetto Dunes’ lagoons and lakes capture stormwater runoff from roads and yards. This allows sediment and pollutants to settle, moderates storm surge, and prevents flooding. The spillways and storm drains trap and treat runoff to protect water quality and they need to be free of obstructions like large trees and debris that impede the flow of water. It is important to prevent plants from growing over inlet pipes and outfalls.

It is important not only to keep the lagoon and lakes looking beautiful, but also to keep the water quality healthy for the fish and wildlife habitat.

There is a twenty (20) foot vegetative buffer on every waterfront property in Palmetto Dunes. This buffer protects our lagoon system by filtering fertilizers, pesticides and other pollutants before entering the water.

Removal of any tree/shrub/vegetation from the buffer requires Town approval prior to being approved by the Palmetto Dunes ARB, and may require mitigation.

The following activities are prohibited in the wetland buffer without prior Town and ARB approval:

  • Removal, excavation, or disturbance of the soil;
  • Dumping or filling with any materials;
  • Placement or replacement of any sod;
  • Placement of any garden of any type (e.g., vegetable, fruit, ornamental);
  • Placement of structures or other pervious or impervious surfaces (except pervious pedestrian walkways with Town and ARB approval); and
  • Removal or destruction of trees, plants or grasses.
