Summer time is a great Rain washes anything that’s on driveways, streets and paved surfaces down storm drains and into lakes and rivers. Chemicals on dirt and gravel can also soak into groundwater, which is a source of drinking water for 75% of Minnesotans. Help protect our water:
Goldfish are a non-native, invasive species that interrupt normal ecosystem processes when they become established in a waterbody. They actively disturb pond bottom sediments in search of food, causing low water clarity. This also makes nutrients like phosphorus available for algae to use, leading to unwanted blooms. It is very important that goldfish are not […]
Have you seen this purple flower before? While Purple Loosestrife may look appealing, it is an invasive plant, causing ecological havoc. Purple Loosestrife (Lythrum salicaria L.) is a highly invasive plant that is often found along shorelines. The plant was introduced to the US in the 1800s as an ornamental species native to Europe and Asia. […]

Each year in Minnesota, we spread about 445,000 tons of de-icing salts on our roads, sidewalks, driveways, and parking lots. These road salts are made of chloride and are the number one cause of chloride pollution in Minnesota waterways and groundwater. But there are ways to prevent further chloride pollution. De-icing with chloride salts is […]
Could harvesting biomass of cattails reduce nutrients and improve water quality in Armstrong Lake? The South Washington Watershed District has launched a pilot program to find out. Cattails are a species staple of Minnesota lakes and ponds. The aquatic plant grows tall and dense, quickly dominating shoreline environments. While cattails may all look the same […]

What’s in your drinking water? Groundwater provides 100% of drinking water to those living in the South Washington Watershed District, whether it’s city pipe or a private well. While city piped water or tap water and well water in the area both come from the same source, how they are handled is different. Tap water […]
Have you ever been walking near a pond or lake and spotted what looked like a green, slimy substance on the water’s surface? You may have been seeing Blue-green algae, a harmful bacteria bloom that can occur when the temperature goes up, and nutrients are high. While Blue-green algae is often referred to as algae, […]
