IMPAIRED SEGMENT (IR CATEGORY 4a)


Introduction

This is the most recent water quality assessment information for this waterbody segment. The assessment is based on water quality data that meet the quality assurance requirements of DEC’s Division of Water. An outline of the process used to assess the quality of New York State waters is described in the DEC’s Consolidated Assessment and Listing Methodology (CALM). The CALM describes the assessment and listing process to improve the consistency of assessment and listing decisions.

WATERBODY INFORMATION

Assessment of Best Use

Background

New York State waterbodies are classified to reflect their best use(s) and the assessment of a waterbody is based on the ability of waters to support them. This section lists whether this waterbody segment supports its best use(s). View DEC’s CALM for more information about the terms used below.

Water Quality Monitoring Data Used

Background

Water quality monitoring data are collected by DEC’s Division of Water and community partners. While data are evaluated to assess whether best use(s) are supported, they may not be reflected in the final assessment of best use(s) presented above. The process for conducting assessments of best use(s) is explained in DEC’s CALM.

This section lists the data sources for the pollutants listed in the Assessment of Best Use table.
