LOWELL -- Congresswoman Niki Tsongas announced today that she will be hosting her sixth annual River Day on Saturday, Oct. 13, in celebration of the rivers that connect the Fifth Congressional District, stopping off first in Groton.

The day will feature canoe rides on the Nashua River, a tour of a former Brownfield site in Lowell that is now part of the Concord River Greenway and a tour along the banks of the Merrimack River in Haverhill. Over the course of the day, Tsongas will meet with environmentalists and groups that utilize the rivers to discuss how the rivers are key to the history, culture, economy and natural beauty of the region.

Over the past six years, River Day has made stops in 10 towns around the district, navigating each of the main rivers that form the region's important network of waterways. Tsongas has met with hundreds of environmentalists, business owners, students, volunteer organizations and constituents since she began hosting the event in 2007.

River Day 2012 will feature three stops. The first stop will be at 10 a.m. in Groton at the Petapawag Boat Launch on Nod Road, about 500 yards from the Nashua River Watershed Association headquarters. Tsongas will paddle along the Nashua River and hear from volunteers about the great strides they have made to make this beautiful river cleaner and more accessible.

In April, Tsongas filed legislation that will authorize a study of the Nashua River to ascertain if the river is eligible for the National Wild & Scenic River Designation.

At 10:45 a.m.


, she will meet at the Nashua River Watershed Association at 592 Main St., Groton, to hear from a range of volunteers about the work they have done on the Nashua River.

The second stop will be at 12:30 p.m. at the Concord River Greenway off Davidson Street in Lowell.

The final stop will be at 2:30 p.m. at the entrance to the Bradford Rail Trail in Haverhill located next to the Roma Restaurant at 29 Middlesex St.

"Our rivers have served us well for centuries, powering the mills of the Industrial Revolution, sustaining our health by providing clean drinking water, creating tremendous recreational opportunities and bringing natural beauty to our daily life. River Day is an event I host each year to bring community members together to celebrate the great role our waterways play in connecting and contributing to the Fifth Congressional District," said Tsongas. "Each of the three River Day stops provides an opportunity to recognize the organizations, volunteers and different levels of government working together to sustain and preserve the integrity of these resources."
