In the wake of a storm, rivers, creeks and other bodies of water can become hot spots for pollution. Make sure trash always makes it to the garbage bin to prevent trash from reaching our waterways. 🚮🌧️ 🔗 Visit the link in our bio to learn more about how you can help reduce pollution. #ThinkBlueSanDiego #PollutionPrevention

San Diego is home to many beautiful watersheds that all serve a purpose in maintaining a healthy water supply and ecosystem. Watersheds are not just bodies of water; they include the entire body of land that drains to a common body of water, like the Pacific Ocean. 🏞️💧 The San Dieguito Watershed connects the Volcan Mountains near Julian to the Pacific Ocean through the San Dieguito Lagoon. This watershed is home to a diverse range of habitats and wildlife, encompassing approximately 346 square miles. 🔗 Click the link in our bio to learn more! #ThinkBlueSanDiego #SanDiegoWatersheds

Community Partners
Think Blue San Diego is proud to partner with the following organizations to help educate the public on the importance of the stormwater system and conduct cleanup activities throughout the region.
Founded in 1954, this nonprofit aims to inspire San Diegans to actively conserve and enhance the environment through example, outreach and involvement.
This advocacy group helps educate San Diego’s students about watersheds and wildlife, hosts beach cleanups year-round, and pushes for legislation to improve stormwater health.
Solana Center for Environmental Innovation is a San Diego-area 501(c)(3) nonprofit organization that envisions a world with landfills and oceans free of discarded resources. To achieve this they empower innovative solutions to climate change through education, community engagement, and research.
Started by a group of concerned citizens 20 years ago, this foundation acts as a steward for the San Diego’s namesake river and is dedicated to making it a truly regional asset valued by all San Diegans.
This organization recently challenged San Diegans to take the “ 52 Ways to Love Your Water” pledge and take small weekly actions to help protect our waterways.
