Protecting Lake Conroe – One Storm Drain at a Time
In May 2015, the San Jacinto River Authority (SJRA) completed a comprehensive Watershed Protection Plan (WPP) for the Lake Conroe watershed. This plan is focused on preserving the excellent water quality in Lake Conroe by monitoring current conditions, addressing challenges from future growth, and educating the public on how they can help keep our lake clean and healthy.
Lake Conroe is one of the highest quality waterbodies in the greater Houston area, consistently meeting all Clean Water Act standards for contact recreation, public water supply, and aquatic life. But maintaining these high standards takes a community effort- there are easy, everyday actions we can all take to keep Lake Conroe clean for future generations. For example, proper removal of pet waste, trash pick-up, suitable chemical disposal, and accurate fertilizer applications help to preserve the lake’s ecosystem.
Beyond these every-day actions, the public can further participate in protecting Lake Conroe through the Stormwater Inlet Marking (SwIM) Program, which SJRA launched as a part of the WPP. This nationally recognized initiative is designed to raise awareness about the effects of stormwater runoff. Many people are unaware that rainwater flowing through our streets picks up pollutants from yards, driveways, and sidewalks—and that contaminated water often flows directly into Lake Conroe. The SwIM program serves as a visual reminder: “Only Rain Down the Drain.” By marking stormwater inlets with colorful medallions, neighbors are reminded that whatever enters the drain goes straight to the lake.
This program is a great way for local groups and individuals to get involved in keeping Lake Conroe clean and beautiful. Volunteers physically apply colorful aluminum medallions to storm drain inlets in neighborhoods throughout the watershed. As shown in the graphic these four inch wide medallions feature a green and blue design and serve as a bold reminder of our shared responsibility.
