Watershed Awareness

A watershed is described by the US Geological Survey as a “precipitation collector.” It is, by definition, a geographical area within which all flows to a common point. For example, each of the Great Lakes is the drainage destination of their own watersheds, which in turn combine to form the Great Lakes Basin watershed, draining into the St. Lawrence Seaway and ultimately the Atlantic Ocean. Essentially, all but the smallest watersheds are connected. Click on the images below for links to examples of NBN’s local watersheds.

Every household within a watershed has the potential to influence the quality of water flowing out of it. Storm-water runoff from roofs, across driveways, and into sewers is often discharged straight into water bodies, carrying pollutants picked up along the way. Small actions such as reducing fertilizer and pesticide use on lawns, installing rain gardens, and planting buffer strips along shorelines can have big impacts on water quality.

Our many inland lakes and rivers are the precipitation collectors and a point of heavy activity throughout the year. Shoreline habitats are critical to the health of the entire lake yet this is where the pollutants concentrate and cause the most harm. What we lakeshore homeowners do while “fixing up” our lakeshore property can add to the end result of destroying one of our states invaluable resources, the fragile habitat along lakeshores.

Some changes we make that may damage the habitat are:

• Trucking in sand used to make a beach may end up covering natural gravel which is used by frogs for laying eggs, fish for spawning and by various insects for hatching.
• Removing aquatic vegetation for boating and swimming can create an unstable habitat that is needed for bass to spawn, loons to nest, waterfowl to eat and insects use to live underwater in! Songbirds use shoreline shrubs for nesting while ducks use shoreline grasses for laying eggs.
• Removal of dead fallen trees along the waters edge where bass and various pan fish love to hide also makes it difficult for the turtles and other wildlife who sit atop the tree to sun themselves and take a break from the water.

Do what you can to minimize use of toxic chemicals and fertilizers on your property. Make the switch from traditional mowed lawn to native grasses and wildflowers that require less maintenance. Avoid synthetic fertilizers and pesticides and limit the use of organic ones.

In fact, your property may have enough space for a lightly developed shoreline and a stunning buffer garden such as the one pictured below. The lush plantings on the right were installed two-three years prior to the plantings on the left. Keep in mind that it will take a few seasons to grow your garden. A skilled gardener experienced in native plants is important to keeping unwanted weeds out while the natives become established. See our previous “Sound Up” post to view pollinators enjoying the late summer Asters and Goldenrod seen here.

This Walloon Lake buffer garden is populated with native perennials, grasses and sedges aiding in the reduction of potential runoff from the lawn.

It may sound counter-intuitive: the idea that a “clean” lawn and shoreline may make a “dirty” lake but complicated things are often that way. The experts at North by Nature Landscapes specialize in natural shorelines and landscapes using native plants and materials to stop erosion and replace lost natural shoreline habitats.

Construction site restoration services focus on cost-effective, ecologically responsible, and successful restoration of impacted habitats. At the location illustrated, plants are establishing well and will be blooming with new growth in time for early summer occupation of the residence.

Lake Shoreline Erosion, Emergency Repair, Natural Shoreline Restoration: Short-rooted turf grass is no match for waves or flowing water. Over 90 cubic yards of soil washed into Black Lake over a 14-year period. Within 4 days we stabilized the bank and created a seedbed for deep rooted plants.
