         These data were produced as part of the U.S. EPA's Environmental
         Monitoring and Assessment Program (EMAP).  If you publish these
         data or use them for analyses in publication, EPA requires a
         standard statement for work it has supported:

         'Although the data described in this article have been funded 
         wholly or in part by the U.S. Environmental Protection Agency 
         through its EMAP Surface Waters Program, it has not been

3.  DATA SET ABSTRACT
    3.1 Abstract of the Data Set
         The benthos community within a stream is an integral
         component of stream biological integrity. This data set
         contains a list of species and counts of numbers of
         individuals of each species collected at each stream
         sampled.

    3.2 Keywords for the Data Set
         Benthos assemblage, benthos community, benthic
         species identification

4.  OBJECTIVES AND INTRODUCTION
    4.1 Program Objectives
         The Environmental Monitoring and Assessment Program (EMAP) was
         designed to periodically estimate the status and trends of the
         Nation's ecological resources on a regional basis.  EMAP provides
         a strategy to identify and bound the extent, magnitude and location
         of environmental degradation and improvement on a regional
         scale based on a probability-based statistical survey design.

    4.2 Data Set Objective
         This data set is part of a demonstration project to evaluate
         approaches to monitoring streams in EMAP.  The data set contains
         the results of multi-habitat sample of the benthos assemblage taken
         during spring low-flow.

    4.3 Data Set Background Discussion
         The benthos assemblage within a stream is an integral component of
         stream biological integrity and represents a publicly visible
         reflection of stream quality.  This data set contains a list of
         benthic species and counts within the stream at the time of sampling.

    4.4 Summary of Data Set Parameters
         The benthic assemblage parameters include individual
         counts and percentages of the sample for certain families of taxa,
         trophic function groups, and pollution tolerant and intolerant taxa.

5.  DATA ACQUISITION AND PROCESSING METHODS
    5.1 Data Acquisition
         5.1.1 Sampling Objective
           To obtain a sample of the benthos assemblage within a stream 
           during a sampling window from July through October.

         5.1.2 Sample Collection Methods Summary
           The assemblage was sampled using modified kicknet with 595 micron 
           mesh distributed in multiple habitats throughout the stream.
