After conducting tests, Parks and Recreation staff have found the presence of aquatic life that can produce swimmer’s itch in the Echo Dale Regional Park swim lake and boat lake.
Swimmer’s itch is an itchy rash people may get from shallow, warm water. It may appear in outdoor water bodies during warmer weather.
Staff are working to further treat the water in the swim lake to reduce its presence.
We’ve posted signage on-site, and it’s still ok to enter the water. If you do, here’s what you need to know:
• The rash isn’t contagious or dangerous, just itchy.
• It typically disappears after about a week
• Shower and towel off right after swimming to reduce the chance of getting it

What is swimmer's itch?
Swimmer's itch is a rash caused by an allergic reaction to the larvae of certain parasites. The parasites can get under your skin when you swim in freshwater (such as lakes and ponds) and sometimes salt water. But you can't get swimmer's itch from swimming pools that are treated with chlorine.
The tiny parasites infect birds or mammals and lay eggs. Bird and mammal droppings that contain the eggs get into lakes and ponds. The eggs hatch into larvae, which then infect snails. The snails in turn release the larvae into the water, where the larvae look for a host. If they come in contact with people, the parasites can burrow under the skin. This causes an allergic reaction and a rash.
But the larvae can't survive in humans, so the parasites die. As a result, the rash usually goes away on its own and doesn't need treatment. The rash can't be spread from person to person.
What are the symptoms?
Symptoms of swimmer's itch include:
A rash that usually goes away in about a week.
An itching or burning feeling on your skin.
Bumps on your skin that show up minutes or even days after you were in the water. The bumps may later turn into blisters.
How severe the rash is may vary for people exposed to the same parasites.
How is it diagnosed?
A doctor can diagnose swimmer's itch by looking at your skin and asking if you've been swimming in ponds or lakes.
How is swimmer's itch treated?
In most cases, swimmer's itch goes away on its own, so you don't need to see a doctor.
To treat the itching at home, you can:
Put cool wet cloths (compresses) on your skin.
Use anti-itch creams that you can buy without a prescription in a grocery store or drugstore.
Put calamine lotion on your skin.
Add a handful of oatmeal (ground to a powder) to your bath. Or you can try an oatmeal bath product, such as Aveeno.
