The 2009 Gills Creek Watershed Management Plan, originally prepared by Tetra Tech and BP Barber, was updated in order to reflect changes in the watershed’s condition over the last ten years and to provide a more explicit listing of projects within the Gills Creek Watershed, along with predicted costs and expected results. Public input allowed pollutant “hotspots” within the watershed to be identified, helping to guide many of the specific projects within this plan. The report provided herein addresses EPA's nine required elements of watershed-based plans, including information such as: pollutant causes, sources, and amounts; current and predicted future development conditions; flooding concerns; best management practices; community engagement; and a schedule for implementing the plan, as well as measures of its success. This updated plan will provide myriad options not only for GCWA, but for local governments and others in the watershed. It is meant to be a living document, adjusted as needed to reflect watershed conditions and accommodate new threats, opportunities, and community concerns.

Following development of the Gills Creek Watershed Management Plan, a more specific plan focusing on the Middle Watershed was prepared in 2013 by Wood+Partners Inc. and McCormick Taylor, with support from Richland County.

Middle Watershed Plan


Planning for better management of the Gills Creek Watershed began in the mid-1900's with a report prepared by the Department of Health and Environmental Control. However, thinking about improving the watershed began even earlier, with a report prepared at the turn of the last century.

A streamlined Strategic Plan was approved by the GCWA Board in May, 2019. It will be augmented with specific annual plans on a continuing basis. The plan builds on principles established through an earlier plan developed with input of community stakeholders, volunteers, board members, and staff, facilitated by the River Network. It has been updated annually since then.
