Charles River Herring Run 2017

Posted by Elisabeth Cianciola

Blog post by CRWA's Aquatic Scientist

The herring are back! It's that time of year; alewife and bluback herring have once again returned to the Charles River to spawn. Estimates of the river herring population on the Charles run upwards of 300,000 fish, making our herring run one of the largest in Massachusetts. Based on historic observations, we expect that the majority of herring, approximately 80% of the run, will pass through the Watertown Dam within the next week. The fish ladder the herring will use to swim against the current over the dam is on the southern bank of the river, but you can easily see the fish waiting in calmer waters under trees just below the dam from the Charles River Greenway on the north bank of the river. If you have polarized sunglasses, you can get an even better view! If you are unable to walk or bike to the Watertown Dam, limited parking is available at the DCR parking lot off of Pleasant Street on the north side of the river and on the side of California Street on the south side of the River. Fish that pass over the Watertown Dam continue their journey upstream in search of streams that feed into the Charles River, such as Beaver Brook and Stony Brook in Waltham and the newly-restored Fuller Brook, Rosemary Brook, and Waban Brook in Wellesley. Some herring do not continue up to the Watertown Dam after passing through the locks at Boston Harbor and instead swim up the Muddy River in Boston. If you see herring or other fish in the Charles River or one of its tributary streams, send us your photos on Facebook or Twitter!

Stocking the Charles River with Trout

Posted by Nick King

Guest blog post by fisherman, retired Boston Globe writer and CRWA volunteer Nick King

Much has been written, and rightly so, about the tremendous progress that has been made in cleaning up the Charles so that it is, at times, a swimmable river. Much less publicized is the fact that the Charles is increasingly fishable too, and I don’t mean just for its plentiful native bass, pickerel, carp and panfish but also for the wiliest and most sought-after species the trout.

Green Budget: Massachusetts needs 1% for the environment

Posted by Alexandra Ash

Currently only 0.5% of the state operating budget supports environmental agencies, agencies that are asked to do more with less—including responding to the drought, reducing emissions, ensuring clean water and preparing for the impacts of climate change.CRWA, as a member of the Green Budget Coalition, advocates for allocating 1% of the state budget for the environment. The Green Budget recommendations include increased spending for climate change adaptation, improving water quality, protecting wetlands, restoring habitat and maintaining parks.

Charles River Flows Free

After more than a year spent permitting the project and four months of on-site work dredging sediment and deconstructing the Old Mill Dam, the Charles River now flows freely from the North Bellingham dam to the West Medway dam. Although revegetation of the river banks and the newly-capped backwatering area that has been filled with dredged sediment will take several months (not much will grow through the recent snow!), the restoration project is now complete with the exception of the construction of a stormwater treatment basin that will clean runoff from Pearl Street before it makes its way to the river.

The Muddy River Then and Now: Water Quality in 2006 vs. 2016

Posted by Elisabeth Cianciola

1/23/17 5:33 PM

The Muddy River, which runs a course of 2.9 miles from Jamaica Pond to the Charles River, is the most significant tributary of the lower Charles River. As a prominent feature of the famous Emerald Necklace parks, its fate was marginally better than most tributaries of the lower Charles in that it was only partially buried and not completely buried in the frenzy to make more land available around Boston in the early 1900’s. Nonetheless, the river was seriously impacted by this human interference. The river lost some of its natural ability to flush sediment that accumulates in the river as a result of stormwater runoff and was unable to adequately dissipate flooding across its floodplain. Severe flooding in the 1990’s made it clear that the human-altered Muddy River system was not working, and an effort to restore the river’s natural characteristics was needed.

Removing dams can improve river health

Updated 3/23/17

Built to generate power for industry in the 18th and 19th centuries, dams served an important role in the history of the Charles River watershed. However, dams slowed the flow of the Charles River, hampering its ability to cleanse itself. Dams also prevented migratory river herring from reaching upstream reaches of the river to spawn. While some Charles River dams provide flood control, many of the dams on the Charles River bring more problems than benefits. When dams become obsolete, their removal can benefit rivers and the surrounding communities. These Frequently Asked Questions discuss the benefits and challenges of dam removal.

The Year in Review- Highlights from 2016

Posted by Alexandra Ash

12/14/16 9:59 AM

2016 marked important milestones for the restoration of the Charles River and its watershed: the elimination of heat pollution from the Kendall Power Plant, the daylighting of the Muddy River, and the removal of the hazardous sandbar near Brighton. 2016 also saw the worst drought since the 1960's, persistent stormwater pollution, another cyanobacteria bloom in the Charles River Lower Basin, and the nomination of a new US EPA Administrator who questions climate change. Through it all, CRWA passionately continued our work throughout the watershed developing smart, green water infrastructure, promoting restorative ways to reduce stormwater pollution and flooding, and advocating for strong and effective water policy and regulations. We couldn't have done this work without you—thank you! 

Below are just a few of the highlights from 2016.

Bellingham Old Mill Dam

12/20/2016 Update: The removal of the Old Mill Dam in Bellngham has begun!

 

This year, the Town of Bellingham will begin work to remove the Old Mill Dam on Peal Street in Bellingham, making Mill Dam the first Charles River dam to be removed. The Town of Bellingham is the first town to begin a dam removal project in the Charles River Watershed. This project was made possible with financial support from the Massachusetts’ Executive Office of Energy and Environmental Affairs Dam and Seawall Repair or Removal Program and technical support from the Department of Fish and Game’s Division of Ecological Restoration (DER). Removing the dam, which is unsafe in its current state, will reconnect 9.2 miles of river habitat upstream of the dam to 50 miles of unobstructed river downstream.

Collaboration Toward a Greener Future

Since 1949, the Kendall Cogeneration Station, located near Longfellow Bridge and now owned by Veolia, had been withdrawing 77 million gallons of Charles River water to cool its three turbines. Called “once-through” cooling, the water was pumped through a piping network and used to convert the steam that had already given up most of it’s energy to making electricity back to liquid water.  This cooling water did not contact the steam but absorbed heat that was then discharged back to the Charles River from 10-20 degrees warmer than when withdrawn. The daily volume used ( 77 million gallons) is often greater than the flow of the Charles in summer. Since the ambient surface temperature of the Charles can reach 85 degrees in the summer, the added heat upsets the river ecosystem, contributes to algal blooms, and has contributed to fish kills.
