A Special Message from our Executive Director:

First and most importantly, thank you for your continued support. Everything we do to protect the quality of our water in southwest Florida is made possible due to dedicated and gracious donors, like yourself. Thank you, thank you, thank you.

Since taking on the role of Executive Director four months ago, I have been listening to donors, businesses, and leaders in our community. The good news is that I have learned so much from the feedback. Most importantly, I have realized the importance of being clear to you about who we are, what we do, what we have accomplished, and our future plans. Communication is critical, and because of your feedback, I am providing some clear information on the work of Calusa Waterkeeper.

Calusa Waterkeeper

Who We Are. What We Do.
What We Have Accomplished.
And, Calusa Waterkeeper’s Plans for the Future.

Cassani shallow water testing


Calusa Waterkeeper and its supporters LOVE our waters and are fighting to protect human health, aquatic life, our local economy, and our piece of paradise in Southwest Florida. We do all of this through science-based research, public education, advocacy, social innovation, water and air monitoring, the hard work of countless volunteers and listening to our community. All of this is made possible solely by the support of gracious donors such as yourself.

We are Calusa Waterkeeper, and we are guided by science
to protect our water quality and human health.

What Makes us Unique

• We utilize science-based research and education to guide our work and advocacy
• We focus on water quality’s impact on human health
• We work on specific issues in our own community, like Billy’s Creek, Manuels Branch, the Caloosahatchee River, Cape Coral Canals, the Estero Bay watershed, and others impacting our communities
• We have a community of volunteer Rangers monitoring local waterways and advocating on behalf of improving water quality

Distributed Leadership

Innovative solutions demand an innovative model, and at Calusa Waterkeeper we are uniquely designed for a “leaderful” operation to create greater regional impact. With Waterkeeper John Cassani, the volunteer Board and Executive Director Trisha Botty leading the way, we are more resilient, attentive, and vigilant to the needs of our community.
