Sparkill Creek Watershed Alliance (SCWA) is a 501c3 non-profit organization established in 2010. We obtained our 501c3 designation in 2015.  Our community effort brings together creekside neighbors, family, friends, community organizations and businesses to learn how to care for our creek, so that it is here for generations to come.Water quality is a local, even hyper-local issue that can be addressed with local solutions.  Please join us at our next Citizen Action Meeting to learn how you can help.
