Stormwater Drainage & Swim Advisory in Myrtle Beach
Yes, our beach is safe. Sometimes the news media causes “alarm” about beach water, those of us who live here understand what is really going on and we hope the information below will help educate you. Please read the facts below.
Most important take away: after it rains really hard for a period of time, the rain drains more quickly, and that does not give nature enough time to “clean” the storm water draining off yards, parking lots and roads. Generally, it takes less than 24 hours for bacteria levels to return to normal (OLFC’s is usually 10 or less – the trigger is 104+). AND you only need to avoid the outfall pipes (those little streams of warm water draining onto the beach): “Swimming is not advised within 200 feet in each direction of this swash/stormwater outfall.”
Know the Truth, Know the Facts
DHEC samples water at the state’s beaches twice a month starting May 1 to October 1. Beaches in the Myrtle Beach area are sampled weekly. You can see test results here. Ocean Lakes has two swashes that are tested.
Guests are confused by some recent headlines and social media posts regarding a no swim advisory. Sadly there has been some misleading information on the web and our team would like to address the issue. When concerned guests and home owners call Ocean Lakes with questions, we want to make sure our teammates are giving them the correct information. We know that vacations are important, but that health and safety come first. As local residents we understand the stormwater drainage issues and the swim advisories, we need to help Myrtle Beach guests understand.
Is it Safe to Swim in Myrtle Beach?
Yes! It is safe to swim in Horry County (including Myrtle Beach). Know the facts! Below are some tips for families and the facts about the issue.
OLFC continues to be in communication with SC DHEC’s Beach Management in the Myrtle Beach Office, located on Shine Ave., (843) 238-4528 to discuss what Long Term Swim Advisories mean and bacteria levels.
Here are the facts that SC DHEC stated to Ocean Lakes Family Campground:
- The beach is not closed because of high bacteria levels, that information was incorrect. The news stories started due to one source/story.
- The beach [all of the Myrtle Beach/Grand Strand] is open for swimming.
- DHEC installed caution signs in 2007/2008 at the request of the City of Myrtle Beach to forego the need for press releases every time a stormwater discharge location tested high for bacteria after strong rain storms.
- We have been under a constant (long term) advisory since the signs were installed at the swashes/outfalls/stormwater discharge locations in 2008 (in Horry County) in 2007 (City limits).
- BASICALLY: If the signs were taken down, the long term swimming advisory would go away!
- The swimming advisories are only for the areas directly adjacent to the outfalls (200 ft range).
- When a swash/outfall location tests high for bacteria it is only high for a brief period of time before it dissipates (about one day).
- Water is tested May 1 – October 1 when the weather is most conducive to bacteria growth.
Water Tested to Dispel Any Concerns – We Live and Play Here, too
Myrtle Beach takes water quality seriously. DHEC collects more than 40 water samples from various locations in Horry County along the Grand Strand (Myrtle Beach area). Learn more about SC DHEC’s Beach Management and monitoring.
What Areas of the Beach are the Swimming Advisories located in?
They are located where the pipes to the drainage systems (carrying storm water) end. These pipes located along the Grand Strand beaches are referred to as swashes/outfalls/stormwater discharge locations. You see them along the sand dunes line. They often have a shallow stream or gully of water meandering it’s way to the surf. Some people assume they are small tidal pools, but they are made of water draining off the inland. You can view a map of the stormwater discharge locations that are monitored by DHEC on their website.
See Caution Signs on the Beach?
READ them carefully! LOOK closer at WHAT they actually say. The KEY word is “MAY.” These signs were posted in Myrtle Beach and Horry County in 2007 – 2008. Some news sources are making a big deal about a “long term swim advisory.” It was explained by DHEC officials that these SIGNS are the reason it is called “long term” advisory. As far as coastal states go, South Carolina is exceptionally vigilante about monitoring the bacteria levels along its coast.
The signs say:
- “High bacteria levels may be present at this location, especially in days following rain due to storm water runoff.” See the photo to the left, we circled this in yellow and see the green arrow.
- “Swimming is not advised within 200 feet in each direction of this swash/stormwater outfall.” This copy is located inside the pink box in the photo on the left.
- “Wading, fishing, and shell collecting do not present a risk.” Also stated in the pink box to the left.
What Causes the Bacteria Levels?
Animal pollution (waste) can be a major source of bacteria and excess nutrients in local waters. (This is one reason that Ocean Lakes strongly encourages guests to pick up after their pets, see our iCare Program and Policies.) Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. Learn more about stormwater on DHEC’s site or the EPA brochure. Learn how to help prevent runoff/stormwater pollution.
Tips for Ocean Lakes Family Campground and Myrtle Beach Guests:
- Each Swim Advisory is short lived, bacteria levels generally return back to normal range within a day or so.
- Understand it is not the beach/ocean water that is testing high, it is the water draining out of the stormwater discharge.
- Do not play or swim in the swashes/outfalls/stormwater discharge locations. We often see young children and parents gravitate to these areas because the water there is warm, shallow and gentle. Avoid these areas on the beach. We have two areas in along the mile of Ocean Lakes beachfront, one at the far northern perimeter, and one more central south of the basketball courts and playgrounds (see slide photo at the top of the page).
- The biggest concern is with young children or people with compromised immune systems. They can still enjoy the beach! Just avoid the water in the swash areas.
- Understand that Swimming Advisories are not unusual. They may only be “active” at one or two locations, depending on the test results.
- Signs are posted to alert beach goers and bacteria levels may or may not rise within 200 feet of these signs immediately after a rain event.
Facts from the Myrtle Beach Area Chamber of Commerce:
- The beaches throughout the Myrtle Beach area are open, the water is fine and swimming is allowed.
- We do NOT have a “no swimming” notice or advisory for any beaches in our area.
- We do test the ocean water twice a week in the summertime at various locations along the Grand Strand. Only during testing, a short-term advisory applies to small areas (200 feet north and south) at the testing locations, out of an abundance of precaution.
- Hundreds of thousands of locals and visitors swim in the ocean every weekend during the summer with no issues.
