This data release includes concentrations of 24 per- and polyfluoroalkyl substances (PFAS) and physical properties of water-quality samples collected by the U.S. Geological Survey (USGS) at 64 selected sites in rivers and streams in Massachusetts over three rounds of sampling. The samples were collected from August to November 2020 when streamflow conditions were below normal (also considered to be base-flow conditions) at rivers and streams in urban areas that receive treated wastewater from municipal wastewater-treatment facilities, and in rural rivers and streams that are not associated with municipal wastewater discharges and may have other source inputs of PFAS. The measured physical properties include water temperature, specific conductance, pH, dissolved oxygen, and turbidity and the quality-control data from blanks, replicates, laboratory control samples, and laboratory spike samples are provided. The physical properties, along with all of the discrete water-quality PFAS data, except the quality-control data, are also available online from the U.S. Geological Survey's National Water Information System (NWIS) database (https://nwis.waterdata.usgs.gov/nwis). This data release is structured as a set of tab-delimited (.txt) files.The metadata includes descriptions of files: Site_Information.txt, Abbreviations_and_Remark_Codes.txt, and Analysis_Information.txt. This data release also includes a Data Dictionary (Data_Dictionary.txt) that is used to describe environmental sample data (Environmental_Data.txt), and Quality Control field and laboratory blank data (QC_Blanks.txt), field and laboratory replicate data (QC_Replicates.txt), and laboratory control sample and spike data (QC_Laboratory_Control_Samples_and_Spikes.txt).
These GIS point show Chapter 91 (The Massachusetts Public Waterfront Act) non-water dependent sites along the coast of Massachusetts. All sites have some form of public access. Data were collected from Massachusetts Department of Environmental Protection (DEP) Waterways Program (http://www.mass.gov/dep/water/resources/waterway.htm). In addition to the physical location, all sites also have hyperlinks to photos and Ch. 91 licenses, as well as a list of amenities. Through Chapter 91, the Commonwealth seeks to preserve and protect the rights of the public, and to guarantee that private uses of tidelands and waterways serve a proper public purpose. Examples the Chapter 91 licensing process include: strolling rights in intertidal areas, pedestrian and waterfront walkways, dinghy docks, public boat landings, public restrooms, public meeting rooms, transient dockage, public water transportation facilities and services, creation of parkland, boat ramps, piers and floats for public recreational boarding facilities, fishing piers, public sailing programs, interpretive display, and interior facilities of public accommodation in private buildings, such as restaurants, museums and retail stores.
Authorities: M.G.L. c. 91: Public Waterfront Act; 310 CMR 9.00: Waterways Regulations. Jurisdiction: Dredging, placement of structures, change in use of existing structures, placement of fill, and alteration of existing structures in any of the following coastal areas (recognizing that MGL Ch. 91 applies more broadly than to coastal areas): * Flowed tidelands - projects in, on, over, or under tidal areas between the mean high water (MHW) line and the limit of state territorial waters (generally 3 miles from shore). * Filled tidelands outside Designated Port Areas (DPAs) - projects up to the first public way or 250 feet from MHW, whichever extends farther inland. * Filled tidelands inside DPAs - projects between the present and historic MHW (i.e. all filled areas inside DPAs). For moorings, floats, rafts, and other bottom-anchored structures, an annual Section 10A permit may be obtained from the local harbormaster in lieu of a Chapter 91 license. Applicability: Any project proposed in, under, or over flowed or filled tidelands or great ponds requires a Chapter 91 license or permit. A Simplified Chapter 91 Waterways License is available to owners of small residential docks, piers, seawalls, and bulkheads. Water-Dependent Chapter 91 Waterways Licenses cover all new or unauthorized water-dependent use projects that are not eligible for the Simplified License. All new or unauthorized nonwater-dependent uses must obtain a Nonwater-Dependent Chapter 91 Waterways License. The term of a Simplified License is 10 years, all others are 30 years. Work not involving fill or structures, such as dredging, may apply for a Chapter 91 Waterways Permit. The term of a Permit is 5-10 years. Regulatory The Division of Wetlands and Waterways in the Department of Environmental Protection (MassDEP) administers the Chapter 91 Waterways Program. Chapter 91 is the Massachusetts public trust statute and, as such, protects the public's rights to fish, fowl, and navigate below the current or historic high water line, as well as in great ponds and navigable rivers and streams in Massachusetts, the so-called public trust lands. Waterways regulations promote the preservation of tidelands for water-dependent uses that require direct access to the water. In addition, the regulations seek to ensure that areas in jurisdiction are maintained for public use and enjoyment when privately developed. Projects are reviewed to ensure that they: (1) do not unreasonably interfere with navigation, (2) are structurally sound, (3) provide a proper public purpose, (4) do not interfere with public rights or rights of adjacent property owners, (5) will not adversely affect natural resources, and (6) preserve DPAs for maritime industrial use. Review Process: The applicant must provide MassDEP with the proposed project location, type of project, project plans, information about other applicable state permits, a certification that the project does not violate municipal zoning, and notification of the municipal planning board. Projects are subject to a 30-day public comment period advertised in a newspaper of general circulation. Nonwater-dependent projects also require a public hearing. MassDEP licensing decisions are subject to a 21-day appeal period. The Chapter 91 License must be recorded at the Registry of Deeds with the property's chain of title within 60 days of issuance or the license becomes invalid.

This layer depicts the portion of the Riverfront Area (RFA) located in Massachusetts that is known as the “Densely Developed Area” (DDA). The DDA is a 25-foot wide RFA located adjacent to both sides of a river established through the Massachusetts Rivers Protection Act, Acts of 1996 Chapter 258, that is regulated through the Massachusetts Wetlands Protection Act, Massachusetts General Law 131 § 40. The RFA, including the DDA, was established to protect the following interests: private and public water supply, groundwater, flood control, storm damage prevention, pollution prevention, land containing shellfish, wildlife habitat and fisheries. DDAs were established directly by the Rivers Protection Act, the Massachusetts Department of Environmental Protection (MassDEP) through regulation upon initial adoption of the regulations implementing the Rivers Protection Act in 1996, and thereafter by the Massachusetts Secretary of the Executive Office of Environmental Affairs (now Energy and Environmental Affairs or EEA). The DDA designation recognizes the RFA is narrow in established densely developed areas. See metadata here…Feature service also available here…

This Feature Service published by MassGIS represents Mouth of River (MOR) lines for Massachusetts coastal rivers originally published by the Massachusetts Department of Environmental Protection (MassDEP) on March 1, 2005 as PDF maps. The PDF maps identify the mouth of the river for coastal rivers in order to provide a clear, consistent, and predictable means of locating all river mouths in the Commonwealth. They are the final MOR maps for each community and represent the culmination of a year's effort that included distribution of draft maps for public comment, receipt and review of over 100 written comments, and field surveys for many of the more difficult mouth of river lines. Each Massachusetts coastal community received a set of maps corresponding to the rivers in their community.
The MOR map lines are intended to
identify where a river ends pursuant to 310 CMR 10.58(2)(c). As provided in 310 CMR 10.58(2)(c) "When a river flows into coastal waters or an embayment, the river shall end at the mouth of coastal river line as delineated on the current mouth of coastal river map series maintained by the Department." represent the limit of Riverfront Area jurisdiction under the Wetlands Protection Act. Land upstream of the MOR line includes Riverfront Areas subject to the protections afforded by the Wetlands regulations; any land seaward of the MOR line is not subject to jurisdiction as a Riverfront Area but remains subject to other inland and coastal provisions of the Wetlands Protection Act.By adopting a uniform approach to mapping river mouths, this data should reduce the need for individual MOR delineations and in turn provide a predictable means for project review for landowners, conservation commissions and MassDEP.See full metadataAlso see the Map Service.

Study ObjectivesThe primary objective of this study was to generate projections of changes in stream temperature and thermal habitat (i.e., cold water fish habitat) due to climate change across the state of Massachusetts. To achieve this, statistical and machine learning models were developed for predicting stream temperatures based on air temperature and various landscape metrics (e.g., land use, elevation, drainage area). The model was then used in conjunction with climate change projections of air temperature increases to estimate the potential changes in stream temperatures and thermal habitat across the state. The results of this study are made available through this web-based tool to inform conservation and management decisions related to the protection of coldwater fish habitat in MassachusettsModeling MethodologyA regional model was developed for predicting stream temperatures in all streams and rivers across the state, excluding the largest rivers such as the Connecticut and Merrimack. The model was comprised of two components: 1) a non-linear regression model representing the functional relationship between air and water temperatures at a single location, and 2) a machine learning model (boosted decision trees) for estimating the parameters of the air-water temperature model spatially based on landscape characteristics. Together, these models demonstrated strong performance in predicting weekly water temperatures with an RMSE of 1.3 degC and Nash Sutcliffe Efficiency (NSE) of 0.97 based on an independent subset of the observed data that was excluded from model development and training.ResultsUnder historical baseline conditions (average air temperatures over 1971-2000), the model results showed more abundant cold water habitat in the western part of the state compared to the eastern and coastal areas. Forest and tree canopy cover were among the most important predictors of the relationship between air and water temperatures. The amount of impounded water due to dams upstream of each reach was also important. The majority of cold water habitat (82% of all river miles) were found in first order streams (i.e., headwaters), which are also the most abundant accounting for 60% of all river miles overall. The Deerfield and Hudson-Hoosic drainage basins had the most cold water habitat, which accounted for 80% or more of the total river miles within each basin. Coastal basins such as Narragansett, Piscataqua-Salmon Falls, Charles River, and Cape Code each had less than 5% cold water habitat.Using a series of projected air temperature increases for the RCP 8.5 emissions scenario, the model predicted a reduction in cold water habitat (mean July temp < 18.45 °C) from 30% to 8.5% (a 72% reduction) statewide by the 2090 averaging period (2080-2100). Furthermore, projections for larger streams (orders 3–5) were projected to shift from predominately cool-water (18.45–22.30 °C) to the majority (> 50%) of river miles being classified as warm-water habitat (> 22.30 °C).ConclusionsThe projected stream temperatures and thermal classifications generated by this project will be a valuable dataset for researchers and resource managers to assess potential climate change impacts on thermal habitats across the state. With this spatially continuous dataset, researchers and managers can identify specific reaches or basins projected to be the most resilient to climate change, and prioritize them for protection or restoration. As more datasets become available, this model can be readily extended and adapted to increase its spatial extent and resolution, and to incorporate flow data for assessing the impacts of not only rising air temperatures but also changing precipitation patterns.AcknowledgementsI would like to thank Jenn Fair (USGS) for her technical review of the model report and assistance in data gathering at the beginning of the project.
