E coli Level (INP and Rosedale)

Weekly monitoring of bathing water quality has been resumed for Summer 2022. 

The Commissioner of Health Services has established that concentrations of the E. coli indicator organism less than or equal to 235 per 100 mL is generally considered satisfactory. A single sample of the indicator organism greater than 235 per 100 mL is in excess of that which is normally considered acceptable for bathing. Factors that may influence the growth of this organism include large populations of waterfowl, the number of bathers and the amount of rainfall received at the time of testing.

Buffers/Rain Gardens with Native Plants

A rain garden is a depressed area in the landscape that collects rain water from a roof, driveway or street and allows it to soak into the ground. Planted with grasses and flowering perennials, rain gardens can be a cost effective and beautiful way to reduce runoff from your property. Rain gardens can also help filter out pollutants in runoff and provide food and shelter for butterflies, song birds and other wildlife. More complex rain gardens with drainage systems and amended soils are often referred to as bioretention.

At home or prior to your next launch:

  • Dry: anything that comes into contact with water (boats, trailers, anchors, propellers, fishing equipment, clothing, dogs, etc) for a minimum of 1 week.
  • If drying isn’t possible, wash with hot water (preferably high pressure).
  • Never release plants, fish or animals into a body of water unless they came out of that body of water.
  • Dispose any unused bait in an upland trash

Concerns

Plants You See - Be Aware of the Aquatic Invasive Species (AIS)

Invasive
Aquatic invasive species (AIS) are non-native species which crowd out
or outcompete native plants and animals. They often have no natural
predators or interact with the environment in a way that allows them
to grow quickly and aggressively. AIS can create undesirable recreation conditions, cause loss of habitat for wildlife like fish, and decrease ecosystem biodiversity.\
