The creation of the George's Creek Watershed Association (GCWA) began in 1995 as the Mill Run Watershed Association (MRWA). Mill Run, a tributary to George's Creek was inhabited by native brook trout in its headwaters, but became fishless in its lower half due to acid mine drainage (AMD).

Robert Miller, a retired local area school principal, joined with other concerned citizens to form the MRWA to solve problems that negatively impact the Mill Run Watershed such as flooding and AMD.  In order to expand to combat the poor water quality issues effecting George's Creek and its tributaries, the MRWA was disbanded, and reformed as the George's Creek Watershed Association. 

Since its inception in 1998, the GCWA has been committed educating the communities of the George's Creek watershed about water quality issues, involving citizens in community outreach projects and partnering with state and local agencies in their efforts to remediate these problems.  The GCWA has been effective in relieving some AMD and flooding issues in the George's Creek watershed.  However, there is still much to be done.
