  • 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).

Box 60 Rindge, New Hampshire 03461-0060 RECEIVING WATER: Unnamed Wetland Tributary to Pearly Pond (Hydrologic Basin Code: 01080202) -2- NH0101044 CLASSIFICATION: Class B I. 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.

  • Massachusetts Department of Environmental Management Hydrologic Assessment of the Millers River
    Massachusetts Department of Environmental Management Hydrologic Assessment of the Millers River Prepared By: In Cooperation with: Gomez and Sullivan Executive Office of Engineers & Environmental Affairs, Environmental Scientists Massachusetts Watershed 55 North Stark Highway Initiative, Millers River Weare, NH 03281 Basin Final Report, April 2003 Executive Summary ES1.0 Introduction In 1994, Massachusetts embarked on a new approach to environmental management- the Watershed Initiative. The Watershed Initiative is a broad partnership of state and federal agencies, conservation organizations, businesses, municipal officials and individuals. The Initiative is an innovative, results-oriented program that protects and restores natural resources and ecosystems on a watershed basis. Watershed Teams, such as the Millers River Watershed Team, were created with the goal of understanding watersheds and improving the overall health of the ecosystem. This study was prepared for and funded by the Massachusetts Executive Office of Environmental Affairs, on behalf of the Millers River Watershed Team, as part of the Massachusetts Watershed Initiative. The purpose of this project is to provide a comprehensive assessment of the current and potential impacts that human activities in the Millers River Basin have on flow-dependent natural resources. There are numerous human activities in the Millers River Basin that affect the timing, magnitude, frequency, and rate of change of natural flows in the Millers River and its tributaries including: • public and

  • Document Overview January, 2008
    New Hampshire Hydrography Dataset: Fourth Order and Higher Streams Document Overview January, 2008 This document contains a summary of fourth order and higher streams in New Hampshire, based on the 1:24,000-Scale New Hampshire Hydrography Dataset (NHHD). The NHHD is archived in the GRANIT database at Complex Systems Research Center, University of New Hampshire. Description of worksheets in this document: Summary by GNIS Name: Summarizes stream length by GNIS name (Geographic Names Information System, from the U.S. Geological Survey). Please note that multiple streams across the state may have the same name. In these cases, the GNIS ID uniquely identifies individual streams. Stream length totals are therefore based on GNIS ID. Addionally, there are occurrences where streams did not receive a GNIS name. These streams could not be uniquely identified, and therefore were summarized as a group (Unnamed Stream/River). Summary by Stream Order: Summarizes stream length by stream order. Summary by Town Name: Summarizes stream length by town name. Process Steps: Describes GIS process used to extract data required to generate these summaries.
