Title: Final Connecticut Stream Flow Classifications
Originators: Mary Becker, Connecticut Department of Energy and Environmental Protection
Publication date: 20181224
Data type: vector digital data
Description
A characterization of the data, including its intended use and limitations.
Abstract: 
The following stream flow classifications on the map are final and include input provided during the public comment period. The State of Connecticut Stream Flow Standards and Regulations (Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies) define four stream flow class standards:Class 1 is described as a free flowing streamClass 2 is described as minimally altered stream flowClass 3 is described as moderately altered stream flowClass 4 is described as substantially altered stream flowThe regulations include consideration of 18 factors related to the degree of alteration in stream flow when adopting river or stream system classifications. Spatial data for each of the factors was gathered from a variety of best available sources. These sources were available at varying scales. A methodology was developed to consider all 18 factors and determine the class for a particular stream segment. In addition, public comment was solicited and considered to identify the final stream flow classification.For additional information on the classification process, see Section 26-141b-5 RCSA Adoption of river or stream system classifications, Fact Sheet for Stream Flow Classification Process under Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies, Technical Support Document Methodology for Defining Preliminary Stream Flow Classification, and Final Stream Flow Classifications and Statement of Reasons Document.

Purpose: 
The State of Connecticut Stream Flow Standards and Regulations (Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies) final stream flow classifications.  The classifications were developed based on 18 factors related to the degree of alteration in stream flow.  The final classifications also include input provided during the public comment period.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standard for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.2
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
Instructions: On the top of the page, click on the title of the dataset to toggle opening and closing of all metadata content sections or click section links listed horizontally below the title to open individual sections. Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
