The best hope for reducing these problems affecting Sligo Creek’s water quality is the increased use of good stormwater management practices in the watershed, including using fewer impervious surfaces. A denser tree canopy would also help a lot because it manages and cools storm water that enters the Creek. It also provides needed nutrients for our waterway.

The US Geological Survey reports basic water quality indicators on a real time basis from one monitoring stations along Sligo Creek. The USGS data can be found here.
The U.S. Geological Survey maintains a stream gauge on Sligo Creek near Maple Avenue. Friends of Sligo Creek is keeping a record
of the Maryland state standard for Use I waters recorded at this gauge.
Prior to June 30, 2010, the U.S. Geological Survey maintained a stream gauge on the Northwest Branch, less than a mile downstream of Sligo Creek. Friends of Sligo Creek keeps historical records of breaches recorded at this gauge.
