Do you have a creek or stream on your property? If you do, then you are responsible for any stormwater related issues or maintenance of the stream just like any other part of your property. Neither the municipality you live in nor the Metropolitan St. Louis Sewer District (MSD) are responsible for erosion issues or maintenance of creeks.
MSD will investigate blocked creek or stormwater related complaints if you call the Customer Service line at 314-768-6260. However, MSD will only remove debris that is deemed a flooding threat. The property owner is responsible for removing typical debris and branches to keep the creek clean and clear of obstructions just as you would remove them from other parts of your lawn.
Use this Stream Care Guide for Streamside Landowners to both assess the health of waterways around your property and learn the best ways to keep them healthy. Following these yard waste tips will help keep excess organic matter out of creeks and reduce your impact on your watershed by minimizing contaminants and curbing erosion.
