Plaster Creek is a 25.9-mile-long (41.7 km)[2] urban stream in Kent County, Michigan in the United States.

However, local groups such as The Lower Grand River Organization of Watersheds and Plaster Creek Stewards have worked to address these issues.

"Plaster Creek Stewards is a collaboration of Calvin University faculty, staff, and students working with local schools, churches, and community partners to restore the health and beauty of the watershed".

One endangered species Epioblasma triquetra (the snuffbox mussel) lives in the Plaster Creek watershed.

[4] The threatened Beak Grass (Diarrhena americana) as well as Endangered Virginia Bluebells (Mertensia virginica) grows along the banks in some areas.
