We are dedicated to protecting and restoring our region’s waterways and estuaries. We believe our 52 community watershed can have it better. We wo

rk with towns, researchers, and local organizations to offer scientifically-informed solutions to improve the health of our waters. Through region-wide collaboration and a non-regulatory approach, we’re here to tackle big clean water challenges. We are not an advocacy organization and do not impose regulation. We offer grant funding, process facilitation, workshops for skills-based planning, and outreach (like community building and project guidance). We also conduct habitat restoration to help our ecosystem bounce back, monitor our estuaries–from eelgrass acreage data to water temperature and plankton samples–and publish publicly available data about health trends that impact the entire watershed. Every five years, we publish our findings in the freely and publicly available State of Our Estuaries Report. This report includes data and best practices the whole watershed can use in their decision making. We are housed within the School of Marine Science and Ocean Engineering at University of New Hampshire and are part of the National Estuary Program (NEP), a place-based program to protect and restore 28 estuaries of national significance. Our work is guided by a Management Committee of local leaders across varied organizations. This Committee drives the development of our Comprehensive Conservation and Management Plan (CCMP), a plan detailing strategies and actions to tackle environmental challenges and promote sustainable estuary and watershed resources.

Climate Ready Kittery Concept Designs Workshop: Share Your Input on the Future of Kittery’s Coastal Roads on June 9th!

The public is invited to join the Town of Kittery and the Climate Ready Kittery project team for a Concept Design Public Workshop on Tuesday, June 9th from 5-7 PM at the Kittery Community Center.

The workshop is free and open to all Kittery community members, and dinner and refreshments will be provided. Attendees are asked to register online before to the event to ensure an accurate attendee count for food

Over the past year, the Climate Ready Kittery project team has been working with engineers and partners to evaluate current and future flood risks at Whipple Road near Gate 2 to the Portsmouth Naval Shipyard and Route 1 at the Spruce Creek crossing near the Kittery Outlets.

With initial site assessments and flood modeling now complete, the Climate Ready Kittery engineering team has been developing conceptual-level designs for potential infrastructure improvements to help adapt each roadway to be resilient to future coastal flooding.

During the workshop, the project team will share draft designs for flood resilience upgrades for both roadways, as well as invite feedback and questions from the public. Public feedback on the concept designs will be integrated into preliminary engineering (50-60%) designs for each site, which can be used by the Town and partners to pursue future funding, advance engineering projects, and move towards implementation of resilience improvements.

What incredible news! BIG Congratulations to the Town of Durham New Hampshire Administrator and PREP Management Committee Member, Todd Selig; close partner at Great Bay National Estuarine Research Reserve Chris Peter, and PREP former Management Committee Member Jim Chase who is the retired President of the Seacoast Science Center after many years of service! They are three New Hampshire recipients at this year’s 2026 Gulf of Maine Council Awards.

Eelgrass has been at the center of many of our conversations across the Great Bay Estuary this spring. While eelgrass beds along the coast have remained relatively strong, meadows within Great Bay proper experienced a significant decline over the past year and continue to face serious challenges.

In response to the release of PREP’s latest of three 2025 eelgrass monitoring reports, PREP Director Dr. Kalle Matso shared a public letter providing important context around the findings, what they mean for the Great Bay Estuary, and where we go from here.

If you are new to the eelgrass conversation, the letter is a helpful place to start. If you’ve been following along and have additional questions, we've compiled a question-and-answer style resource to support you. It includes many of the common questions we’ve heard from community members and partners across the watershed.

Access and use the resource: https://buff.ly/OlKNAhk

We also recognize that one webpage cannot answer every question or address every concern. PREP continues to extend an open invitation to meet with your community. We will listen to your concerns, and share information, resources, and tools that could support you. Please reach out to PREP Director Dr. Kalle Matso ([email protected]) to start the conversation.

🎨🗑️Marine debris → public art. 🎨🗑️ What if 50lbs of marine debris became the canvas? Earth Tones, a subgroup of the New Hampshire Art Association, partnered through Project Builder to explore turning marine debris into artwork. That idea quickly grew into a collaboration with one of PREP's Climate Impact Grantees focused on debris removal and education.

Now, collected materials from local cleanups are being transformed into an upcoming art exhibition, connecting environmental stewardship with storytelling and creativity.

This effort is also helping open doors for artists to engage in regional climate conversations, including the New Hampshire Coastal Adaptation Workgroup Climate Summit.

📣 Project Builder helps ideas like this take shape, build partnerships, and reach new audiences. Book office hours with Annie if you want to chat before you apply!

➡ Project Builder is a grant proposal incubator designed to help communities develop strong, fundable climate resilience projects. Through a mix of mentorship, strategy-building, and creative problem-solving, the program supports participants in refining their ideas, building partnerships, and identifying funding opportunities.

➡ The program is open to 52 communities across the Piscataqua Watershed who are looking to address extreme heat and/or flooding. Apply by July 1, 2026 (5PM EST): https://buff.ly/Jfs3w6n

If you are new to the eelgrass conversation, the letter is a helpful place to start. It provides context for what PREP is and our role in our community, what the monitoring report tells us and doesn’t, and how we determine trends overtime. It also informs readers what eelgrass is and why it is importance to our Great Bay Estuary. The letter also highlights actions we encourage our communities to continue to take because they support the protection of Great Bay while providing co-benefits to people.

We also recognize that one webpage cannot answer every question or address every concern. PREP continues to extend an open invitation to meet with your community.

PFAS is one of those topics that can feel overwhelming to even start thinking about. That’s why we’re glad that the Great Bay Changemaker Program will host another conversation on the topic this on June 16, 2026 from 5:30–7 PM at the Great Bay Reserve.

Join a panel discussion designed to help NH Seacoast residents better understand how PFAS enter our wastewater systems and agricultural fields, as well as what can be done to reduce risks.

What a weekend at the 2026 Exeter Alewife Festival! 🐟🌊 Recently, PREP had a blast celebrating the return of alewives with the community alongside Dr. Kelsey Meyer-Rust at The Nature Conservancy in New Hampshire. Huge thanks to the Town of Exeter and the Exeter NH Sustainability and Planning / Conservation Commission for hosting such a fun and fish-filled day.

Our Habitat & Water Quality Manager, Trevor Mattera, spent the day chatting with attendees about migratory fish, estuaries, and the many ways healthy rivers connect to healthy coastal waters.

Alewives are pretty incredible. These migratory fish travel from the ocean back into freshwater rivers and streams each spring to spawn, helping move nutrients between ecosystems and feeding everything from ospreys and herons to striped bass and bluefish along the way. They’re basically the estuary’s seasonal delivery service. 📦🐟

Their return is also a reminder that restoration efforts matter. Improvements like dam removals and better fish passage are helping more alewives make their way home. In fact, more than 260,000 river herring returned to Piscataqua Region tributaries in 2021, about a 30% increase from 2016.

Thanks to everyone who stopped by to talk fish, rivers, and clean water with us. Until next migration season. 👋🏻 🌊
