Rain Gardens 101

You may be thinking, why an article on rain gardens? Well what if I were to tell you that rain gardens were a way to better protect our waterways from pollutants and illicit discharges. As rain falls our roads and buildings become victim to potential flooding where it erodes away stream banks, and carries pollutants damaging to human and aquatic life’s health. By creating rain gardens around homes and local businesses, it can reduce the negative impacts of rain by slowing down and soaking up the runoff flowing from roofs and paved surfaces. Well I still have answered your question of why rain gardens? Rain gardens are an effective, as well as an attractive way to do reduce all of these negative issues. It is cost effective and provides low-maintenance feature to your yard.

Creating a Rain Garden

Rain gardens are like bowls or basins in your yard that captures rainwater and allows it to soak into the soil instead of polluting local watersheds. Rain gardens should be located approximately 10 feet away from foundations where water already flows towards (usually a depression in the ground or a spot at the bottom of a slope). Avoid areas where water already pools because it could mean either the water table is too high, or the soil has a low infiltration rate. (To test, dig a 6-8″ hole and fill it with water. If it does not drain completely within 12 hours, it is not a suitable (location).

After find the appropriate location for your rain garden, begin by digging out your rain garden ensuring

it is as level as possible. A rain garden can’t do its job if water just flows out of it, so if there is any slope at all a berm must be built to prevent water from escaping. Be sure the sides have a gentle slope and are rounded, as well as properly compacted the ground to prevent erosion.

Planting your Rain Garden

Pennsylvania is blessed with many beautiful native plants that thrive in our environment along with developing strong root systems. When choosing your native plants, it is best to select species that are grow well in moist soil and are tolerant to influxes of large quantities of water. To make sure you create a beautiful and low-maintenance garden, choose a diverse blend of plants and incorporate native grasses or sedges and shrubs. It is always best to do your research first before buying your plants and having a layout already in mind.

Streamside Buffers

– A Strategy for Pollution Reduction in Our Watershed

When people think about pollutants in a local stream like the Paxton Creek they don’t often think about dirt.  Dirt, or sediment – solid fragmented material, such as silt, sand, gravel, chemical precipitates, and fossil fragments – that makes its way into the stream channel is considered to be a source of pollution.  The Environmental Protection Agency lists sediment as the most common pollutant in rivers, streams, lakes and reservoirs.  Sediment can cause numerous issues in the aquatic environment. In stream beds it disrupts the natural food chain by destroying the habitat where the smallest stream organisms live, causing massive declines in fish populations.  Sediment can clog fish gills, reducing resistance to disease, lowering growth rates, and affecting fish egg and larvae development. 

Sources of sediments include urban stormwater runoff, soil disturbance by construction activities, and farming.  Some sediment comes from natural erosion of flowing water, but severe storm events can cause heavy erosion to unprotected streambanks.  The roots of trees and other plants are the key to stabilizing the banks and keeping soil in place.  That is why re-creating streamside buffers in places where they have been removed has become a very effective strategy to repair damaged streambanks and reduce sediment pollution.

A consortium of government agencies recently pooled their resources and undertook sediment removal and streamside buffer restoration projects within the Paxton Creek Watershed. Participants in the projects included the City of Harrisburg, Susquehanna Township, Lower Paxton Township, and the PA Department of Transportation.  An example of a streamside buffering / restoration project occurred at Shutt Mill Park in Susquehanna Township in 2021.

If you are a landowner with a stream on your property, or if you know one, the PA Department of Conservation and Natural Resources has stream buffer experts who can help you protect and enhance your land.  You can contact them at ra-nrstreambuffers@pa.gov or call 717-705-2820.  Your local municipal stormwater department may also have additional resources to offer.  Not only will you be helping to reduce pollution in your watershed, but you will also be creating better conditions for wildlife on land and in the water.

You can become part of the solution to cleaner water by joining the Paxton Creek Watershed Education Association and helping to spread the word about streamside buffers and other good stewardship practices.  Check our website www.paxtoncreek.org or send us an email at stream@paxtoncreek.org.

News from the Tree Nursery

Seedlings
Potted trees at the Nursery

In the Spring of 2019, our nursery was restocked with 100 new tree seedlings.  Each seedling is about 18 inches in height.  The seedlings were potted in the nursery and will continue to grow until a resident or group in the watershed is ready to plant.  The seedings were obtained from the Dauphin County Conservation District (DCCD) and are native to the area.  They include white oak, red maple, black cherry and winterberry.  Recently, DCCD generously provided additional trees for the nursery.  PCWEA also has trees of varying sizes, up to five feet in height, available from stocking in past years.

Potted trees can be planted anytime of the year as long as they are watered regularly.  Trees that are in locations that cannot be watered regularly should be planted in the early Spring or Fall when they have the greatest chance to survive on their own.

To request a tree or trees for your project, please contact the PCWEA through this website.    

The PCWEA nursery is located in Susquehanna Township and can provide small quantities of trees to groups or individuals wishing to plant trees in the Paxton Creek Watershed. 

Thanks to Gary, who ordered, picked up, and transported the seedlings. And another thanks to all of the volunteers who helped pot them.
