Join us for fun!

Our annual Tip Top Run featuring World Water Day is coming up on March 12, 2016. This event celebrates the eradication of Caulerpa taxifolia and helps to raise friends, funds, and awareness about this amazing resource. These unique courses have one of a kind views of the Agua Hedionda Lagoon and Pacific Ocean. This is a fun run/walk, but it is not a chip race. During the finish line celebration, runners join the World Water Day Festival with live music, education, a beer garden sponsored by Coronado Brewing Company, and lunch from the run’s namesake Tip Top Meats. Lunch includes award winning bratwurst, barbeque chicken, ribs, potato salad, and much more.See you at the lagoon!

Welcome to the Agua Hedionda Lagoon Foundation

Welcome to the wonder of the Agua Hedionda Lagoon. This 400-acre lagoon is home to a wide array of flora and fauna and invites us to appreciate our water resources through such uses as a YMCA day camp, recreational boating, a mussel and oyster aquaculture facility, a white-sea bass hatchery, and a power generating plant. It connects us to a greater world in so many ways. Come join the Agua Hedionda Lagoon Foundation in our work to preserve and protect this valuable resource.

Our mission is to inspire people through education and outreach to preserve the Agua Hedionda Lagoon as an accessible and healthy watershed.
