Exciting news! NOAA Fisheries, in partnership with the U.S. Fish and Wildlife Service (USFWS), has released a new guidance document to help scale up coastal marsh restoration in the mid-Atlantic. This is a big step forward in protecting these vital ecosystems!

#HappyThanksgiving! Today we are thankful for our hardworking staff, our partners, and all of our supporters!

After over 200 years, the lower Bushkill Creek is now free-flowing, reconnecting with the Delaware River and the Atlantic Ocean! This is a major win for nature, bringing huge benefits for migratory fish, freshwater mussels, and overall river health. Watch the before and after of the removal of Dam 2. By restoring these vital habitats, we’re improving water quality in the Delaware River Basin — which provides clean drinking water for millions of people!

Had an amazing time at the 2024 SePRO Corporation Stewards of Water Advanced Skills Training at the SePRO Research & Technology Campus in Whitakers, NC! The seminar covered everything from water quality sampling and monitoring, to algae & plant identification, and new tech for improving water quality in ponds, lakes, and reservoirs nationwide. We learned about nutrient inactivation, aquatic plant & algae control, and so much more to help keep our waters clean and healthy.

We are incredibly grateful for the opportunity to present at this year’s North American Lake Management Society Annual Conference! Our team had the honor of sharing insights and research with industry leaders, lake enthusiasts, and environmental experts. Our Director of Aquatics, Michael Hartshorne, led an in-depth discussion on our ongoing "Swartswood Lake Aeration System Investigation."

Scientists have discovered rare Stone Age engravings depicting net fishing! These intricate scenes were found on stones at the G?nnersdorf site in Germany, dating back roughly 16,000 years. This discovery sheds light on the fishing practices of our early ancestors.

The Connecticut River Conservancy has announced the first-ever detection of DNA from the endangered shortnose sturgeon in the Connecticut River. This discovery was made during an ongoing investigation between Turners Falls, MA, and the Bellows Falls, VT/Walpole, NH area.

A huge thank you to the Maryland Water Monitoring Council for having us present at their 30th Annual Conference! Our Director of Aquatics, Michael Hartshorne, gave a fascinating talk on how climate change is reshaping lake ecology. The impact on our water resources is real, and monitoring these changes is key to safeguarding our lakes and preventing future environmental crises!

Cheers to Chris and Colorado Lake and Reservoir Management Association (CLRMA)! Chris L. Mikolajczyk, Senior Project Manager of Aquatics and Certified Lake Manager at Princeton Hydro, has been appointed President-Elect of CLRMA 2025 Board of Directors. Chris will serve a one-year term as President-Elect, followed by a term as President. In these roles, he will collaborate with CLRMA members to host educational events and promote the conservation of Colorado's lakes and reservoirs. Princeton Hydro is thrilled to support Chris as we continue our mission of delivering sustainable, science-based solutions for water resource management and lake restoration across the country. This mission has recently extended to Colorado, where we completed our first project—a bathymetric assessment of Fairplay Beach Reservoir in partnership with the Town of Fairplay. https://bit.ly/3Zh6peX

The New Jersey Highlands Council commemorated its 20th anniversary by presenting the "Lake Hopatcong Exhibit." This showcase highlighted successful projects funded by the Council. Interactive displays were a key feature of the exhibit. Additionally, participants had the opportunity to examine water samples under microscopes, with guidance provided by Dr. Fred Lubnow, the Senior Technical Director of Ecological Services at Princeton Hydro.
