MRWC Stream BMI Monitoring Program 2017 Summary MRWC visited (3) streams in the late summer of 2017 to add to its BMI program data. Monitoring the bottom dwelling (benthic) aquatic insects of a stream is a useful indicator of stream health. Volunteers were an integral part of this program, particularly in the colection and sorting of samples. MRWC sampled the following (3) streams: o Thousand Acre Brook, Phillipston o Bailey Brook, Gardner o Mill Brook, Athol (6) points on each stream were sampled by a “kick” method, then samples were sorted by insect type for detailed identification by an aquatic biologist. The type and quanity of each species help to identify the relative health of the stream. Results were: Thousand Acre Brook – very good/excellent Bailey brook – very good (high iron?) Mill Brook – good/very good (for an urban stream) A full report will be prepared over the Winter.

  • Official List of Public Waters
    Official List of Public Waters New Hampshire Department of Environmental Services Water Division Dam Bureau 29 Hazen Drive PO Box 95 Concord, NH 03302-0095 (603) 271-3406 https://www.des.nh.gov NH Official List of Public Waters Revision Date October 9, 2020 Robert R. Scott, Commissioner Thomas E. O’Donovan, Division Director OFFICIAL LIST OF PUBLIC WATERS Published Pursuant to RSA 271:20 II (effective June 26, 1990) IMPORTANT NOTE: Do not use this list for determining water bodies that are subject to the Comprehensive Shoreland Protection Act (CSPA). The CSPA list is available on the NHDES website. Public waters in New Hampshire are prescribed by common law as great ponds (natural waterbodies of 10 acres or more in size), public rivers and streams, and tidal waters. These common law public waters are held by the State in trust for the people of New Hampshire. The State holds the land underlying great ponds and tidal waters (including tidal rivers) in trust for the people of New Hampshire. Generally, but with some exceptions, private property owners hold title to the land underlying freshwater rivers and streams, and the State has an easement over this land for public purposes. Several New Hampshire statutes further define public waters as including artificial impoundments 10 acres or more in size, solely for the purpose of applying specific statutes. Most artificial impoundments were created by the construction of a dam, but some were created by actions such as dredging or as a result of urbanization (usually due to the effect of road crossings obstructing flow and increased runoff from the surrounding area).

  • Connecticut River Canals Projected but Never Finished
    Connecticut River Canals Projected But Never Finished Besides the six canals that were built on the Connecticut River, there were, during the period of navigation, a number of other canals strongly discussed and some chartered at different places but not built until the bubble of river navigation burst. In 1825, the War Department had sent an engineer to Barnet who had surveyed three different routes from there to Canada. At large expense, and resulting from mass meetings of citizens held in different localities, surveys were made for a system of canals from Wells River over the Green Mountains to Montpelier, thence down the Winooski to Lake Champlain; from the Merrimac, near Concord, up the Pemigewassett to Wentworth, N. H., and then across to the Connecticut in the town of Haverhill, N. H.; from Concord to Claremont, via the Contocook and Sugar Rivers; from the mouth of Millers River, near Greenfield, to Boston; up the Deerfield Valley to the present Hoosac Tunnel, where the mountain was to be cut through and Troy, reached via the Hoosac River, there to connect with the arteries of canals then being constructed, and thus reaching all parts of the country. A canal was already being constructed northward from New Haven, Conn., to Northampton, Mass. A Canal At Brattleboro In the office of the Secretary of State of New Hampshire is to be seen an act of incorporation for a dam and canal near Brattleboro, evidently intended to avoid the rapid water just below the bridge, which, it is needless to say, was never constructed. The act chartered "The Connecticut River Canal Company," the incorporators being Richard Kimball, Elias Lyman, Amos A.

Proposed Action, Type of Facility and Discharge Location. The above named applicant has applied to the U.S. Environmental Protection Agency, New England Office (EPA-New England) for reissuance of its NPDES permit to discharge secondary treated wastewater with enhanced nutrient removal into the designated receiving water (Unnamed Wetland Tributary to Pearly Pond). In turn, Pearly Pond flows into Tarbell Brook, a tributary of the Millers River which itself is a tributary of the Connecticut River. The facility collects and treats domestic (sanitary) wastewater from Franklin Pierce College (“College”) and discharges that treated effluent into the receiving water. The plant is designed as a 0.14 million gallon per day (MGD) advanced wastewater treatment facility that is composed of, in order that wastewater flow is processed, primary clarification, rotating biological contactors (RBC’s), secondary clarification, phosphorus removal with alum (flocculation tank/clarifier), sand filtration and ultraviolet disinfection.

Supplementary Notes In cooperation with the U. S. Department of Transportation, Federal Highway Administration 16. Abstract This report provides estimates of flood discharges at selected recurrence intervals for streamgages in and adjacent to New Hampshire and equations for estimating flood discharges at recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-years for ungaged, unregulated, rural streams in New Hampshire. The equations were developed using generalized least-squares regression. Flood-frequency and drainage-basin characteristics from 117 streamgages were used in developing the equations. The drainage-basin characteristics used as explanatory variables in the regression equations include drainage area, mean April precipitation, percentage of wetland area, and main channel slope. The average standard error of prediction for estimating the 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence interval flood discharges with these equations are 30.0, 30.8, 32.0, 34.2, 36.0, 38.1, and 43.4 percent, respectively.
