The removal of a dam in the Wynants Kill, a Hudson River tributary, has restored more than a quarter mile of spawning habitat for river herring for the first time in 85 years. Approximately 1,500 dams impede the flow of tributaries and streams throughout the Hudson River watershed. One down . . .Read More
All species and subspecies of sturgeon are imperiled worldwide due to the impacts of human activity. Here in the United States, Atlantic Sturgeon, which spawn in the Hudson River, were declared an endangered species in 2012. If the Lake Sturgeon is to avoid the same fate, further research regarding its life history and spawning habitat is essential.Read More

A new study in Environmental Engineering Science by Beacon Institute's River and Estuary Observatory Network (REON) team documents the effects of Hurricane Irene on the Hudson River and estuary. Data reveal a storm event so powerful it overwhelmed the ocean's tidal influence on the estuary, and moved much of a year's worth of sediments, and their related contaminants, downriver. Threats of increased and more severe storm events due to climate change make the clear case for a regular monitoring presence like REON.Read More
There was a time when every river town in the Hudson Valley was home to commercial shad fishermen. The appearance of their boats and nets on local shores was a certain sign spring had arrived. Tradition taught that the first run of American shad left the Atlantic to spawn in the river’s fresh water reaches when the forsythia were in bloom in late March – early April. Dogwoods signaled the middle of the run. The final run of shad, the largest of the fish, according to Hudson rivermen, occurred when the lilac flowered in mid-May.
In 2010, New York State halted commercial fishing of American shad because of collapsing populations in the river and on the coast. Shad spend most of their lives at sea following an isotherm of 13 to 18 degrees Celsius, moving south and north as the Atlantic waters warm and cool. They migrate up estuaries from the St. Johns in Florida to the St. John in New Brunswick and each in between. George Washington once had a commercial shad fishing operation on the Potomac.
No one reason has yet been identified for the collapse of the fishery. It is possible the blame is shared amongst many causes including: power plant cooling water intakes such as those at Indian Point; a coastal intercept fishery that captures the shad before they can migrate; and zebra mussels that rob the estuary of vital nutrients.

Canadian Government puts a hold on Montreal’s temporary plan to discharge sewage into the St. Lawrence while New York and New Jersey continue to dump a 102 billion liter mix of raw sewage and storm water into the Hudson River and New York Harbor annually.

As has been heavily reported in U.S. and Canadian news outlets, the City of Montreal, Canada was again ordered to halt its plan to dump approximately 8 billion liters of raw sewage into the St. Lawrence River between October 18-25, 2015. Minister of the Environment, Canada said she has:
[I]nstructed Environment Canada to immediately have an expert independent scientific review of all information related to this project conducted [to] ensure the best possible protection for the St. Lawrence.
Although Aglukkaq denies prior knowledge of the sewage dump plan, documents show that Environment Canada has been fully aware of the plan since 2014.
The dumping of raw sewage was proposed to facilitate capital improvements of a major sewer interceptor. But when the plan came to public light in late September, there were immediate public outcries. An irate Erin Brockovich, the consumer advocate and environmental activist, posted on her FaceBook page:
This is pure TNT (Turds N Tampons)… as bad as it gets folks.
City of Montreal spokesperson, Philippe Sabourin disagreed:
The [St. Lawrence] river has a huge dilution capacity, with a flow rate of 6,000 to 7,000 cubic meters per second… It isn’t a major environmental concern.
The flow of the mighty St. Lawrence provides far greater dilution power than most American rivers that are also receiving waters for sewage. For example, the flow of the Hudson River in New York is 600 cubic meters per second, only one tenth of the St. Lawrence. Still, Canada’s plan has stirred international controversy and condemnation from U.S. officials, including some particularly vocal representatives from New York State, which borders 114 miles of the St. Lawrence River upstream of Montreal:
While I realize that the dumping will occur in Canadian waters, downstream from any U.S. communities, I am very concerned by the precedent Montreal is setting for other communities along the St. Lawrence and the lakes. – New York State Senator Patty Ritchie in a letter to the International Joint Commission
If this plan is allowed to move forward, this sewage could severely impact the river ecosystem and wildlife, and the St. Lawrence County tourism industry on which the North Country depends. – Charles Schumer, U.S. Senator from New York.
Senator Schumer urged the U.S. EPA to work with the U.S. Department of State and Canadian Government to devise an alternative plan. Yet, in a statement released by EPA spokeswoman Mary Mears, the agency declined to seek action, stating it had no jurisdiction over a matter that does not impact U.S. waters:
While EPA thinks it’s a really bad idea to discharge 8 billion liters — over 2 billion gallons — of untreated sewage into any water body, the EPA does not have any jurisdiction over this matter because these discharges will not have an impact on U.S. waters,
Meanwhile, each week, New York and New Jersey dump a 2 billion liter mix of raw sewage and storm water into the Hudson River and New York Harbor through combined sewer overflows — a total of 102 billion liters each year.
These raw sewage dumps cause significant environmental degradation, making waters in and around the city unsafe for human contact.
When will our New York representatives issue pleas for protection of the Hudson River’s ecosystem, wildlife, tourism industry and residents from raw sewage? Is the EPA unwilling to issue a statement on the Montreal Sewage dump for fear of calling attention to years of weak enforcement of the Clean Water Act in and around New York City and other cities under their jurisdiction? As pointed out by Les Perreaux of the Globe and Mail, Montreal:
The agency [U.S. EPA] could have also mentioned that Chicago, Detroit, Cleveland, and Milwaukee routinely dump billions of litres of raw sewage into the Great Lakes system.
More than 460 combined sewer overflows in New York City spill raw sewage into New York Harbor each year. Add to that more than40 on the New Jersey side of the harbor, plus an additional 163 in the lower Hudson River to Albany and the extent of the problem becomes clearer (or murkier?).
New multibillion dollar Green and Gray Infrastructure plans for New York City are a step in the right direction, but there are questions whether these upgrades will be enough. Larry Levine of the Natural Resources Defense Council has called attention to the fact that these green and gray infrastructure upgrades will address only two fifths of the combined sewer overflow issue.
According to Levine, the New York City Department of Environmental Protection has already taken steps to weaken Long Term Control Plans meant to close the gap, treating them as a paper exercise:
The first two parts of the agreement — the green and gray infrastructure the city committed to build — along with improved sewer system maintenance and reduced water demand, are projected to reduce annual sewage overflows by about 12 billion gallons per year. That still leaves 18 billion gallons.
Yet, in a classic diversionary move, our outrage over sewage dumping is directed towards our northern neighbors in Montreal, where city officials are rightfully confused by sudden outcries from politicians and regulatory agencies about a practice that has been a regular occurrence in the United States and Canada for decades.

The River and Estuary Observatory Network (REON) research team is working with the Hudson River Pilots Association to provide mariner-friendly data that will assist with safe passage of ships into the Port of Albany. As often happens, REON data first had to be translated into a usable form, in this case for the expert navigators of the association. This is not as straightforward as it might sound. Our engineers use the metric system and typically express the speed of river currents in centimeters per second, which is arcane enough for most of us. But the pilots have the engineers beat: they use “knots.” A knot is one nautical mile per hour, equal to 1.852 kilometers per hour or 1.51 miles per hour.Read More
Acoustic backscatter is a method we use for determining the concentration and movement of particles in river water. Why do we care about particles? One reason is that certain toxins, such as PCBs, attach themselves to river mud and silt, allowing them to be transported downriver by storm events.Read More
