Europe is Demolishing its Dams to Restore Ecosystems
An initiative has begun in Europe to take the first continent-wide census of all dams. And although dam removal is generally welcomed by most scientists, some call for more research into potential ill effects. Princeton Hydro's Laura Wildman, P.E., is one of the dam removal experts interviewed for the story.

“Dam Good Effort: Breaking Through the Money Question for Dam Removals”
Huron River Report, Huron River Watershed Council Publication
The science and practice of dam removal and river restoration falls into two camps. The conventional approach seeks to thoroughly design the new stream based on natural channel design metrics. Princeton Hydro's New England Office Director, Laura Wildman, P.E., has practiced a “less is more” approach on scores of dam removal projects, which offers the dual promise of improved sustainability and lower cost.

Dr. Fred Lubnow, Director of Aquatic Programs at Princeton Hydro, explained to the Harveys Lake Borough Council that the grant will be used to combat the lake's highest densities of hydrilla."

 Old Meriden Dam Torn Down to Make Way for Fish
"Princeton Hydro is on-site at the Quinnipiac River for the Carpenters Dam removal. The removal of this dam opens up 16 miles of river, allowing fish to swim upstream, supporting the expansion of freshwater mussels and other aquatic life, giving outdoor recreationalists more flexibility, and providing countless other benefits."

Using Floating Wetland Islands to Reduce Nutrient Concentrations in Lake Ecosystems
In lake-front communities, the implementation of beneficial wetland systems can be limited by a lack of space. Floating Wetland Islands offer an innovative solution to space limitations and provide many of the same benefits as traditional wetlands. They are mobile, temporary wetlands that can be strategically placed to maximize their nutrient-reducing and habitat-building capabilities.
