Bacteria days: results for June 29, 2017

Dear River and Watershed Friends,

Good news: on our very first day of the season we not only had 100% sampling at 100% of our sites but the E. coli bacteria readings from yesterday are very low.

None of the eleven samples taken yesterday, June 29, 2017, from the Pemigewasset and Winnipesaukee Rivers in Franklin to the the mainstem Merrimack in Bow had levels exceeding 64.5 colonies of E. coli bacteria for every 100 millilitres of water. That’s great news for your weekend because designated swim beaches are not allowed to exceed 88 colonies and Class B waters (all of our sites are Class B waters) should be below 406 colonies. Here are the details.

Site number and description
1 Pemigewasset 21.1
2 Winnipesaukee 13.0
3 Merrimack above FWWT Plant 38.3
4 Merrimack below FWWT Plant 27.2
5 Merrimack Jamie Welch Park 35.5
6 Merrimack Route 4 Bypass 72.3
7 Contoocook at Rivco 64.5
8 Merrimack Sewalls Falls 62
9 Merrimack Manchester St 39.3
10 Merrimack Blue Seal 48.8
11 Merrimack Garvins Falls 36.4

Our next sampling day is Thursday, July 13, 2017 so you will hear from us on July 14.

Thank you to our wonderful Adopt-a-River Site sponsors, sample courier, site volunteers, Adopt-a-River Site sponsors, and the crew at Franklin Waste Water Treatment Plant. There would be no Upper Merrimack Monitoring Program without them.

River Runners™ invasive species training workshop: July 17, 2017 in Bow

Have you seen a new aquatic plant and aren’t sure what it is? Do you care about your local river or stream? Do you want to do more to prevent invasive species infestations? You can help stop infestations in their tracks when you become a River Runner™.

Since 2009, the New Hampshire Rivers Council River Runners have been the early detection network for Didymo, Eurasian Milfoil, and other invasive species in our rivers and streams. Training is fun and free and monitoring is easy—just be observant when paddling, swimming, and fishing in your favorite river and then report what you find. You’ll meet new friends and learn valuable indentification skills.

If you have found an aquatic plant and want to know what it is, you can bring a sample to a River Runners workshop near you. Preserve the sample by placing it in a ziplock bag with a wet paper towel (don’t fill the bag with water) and store it in the refrigerator. Make a note of where the specimen was found and the date of its collection. Do not allow fragments of the plant to spread in the waterbody.

These workshops are free thanks to support from generous gifts from New Hampshire Rivers Council members like you. There is no charge to attend but space is limited so registration is required. Please click here to register.

Prospective hosts: please contact the New Hampshire Rivers Council at 603.228.6472 to arrange a workshop near you.

Setting Rivers Free: river and watershed restoration goes mainstream

The article tells the story of how hundreds of the United States’s rivers and watersheds are being restored. There are many local examples including Black Brook and McQuesten Brook in Manchester and the (former) dam in Town of Merrimack.
