3.  DATA SET ABSTRACT
    3.1 Abstract of the Data Set
         This data set contains stream discharge estimates
         based on one of three methods; Velocity-Area,
         Timed Filling, or Neutrally-Buoyant Object Procedure.
         The method chosen depended on stream channel
         type. The preferred method is Velocity-Area. Smaller
         channels may necessitate the Timed Filling method, or
         very small streams use a Neutrally-Buoyant Object.

    3.2 Keywords for the Data Set
         Current velocity, flow, discharge, stream flow,
         velocity-area, neutral buoyant object, timed filling

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 stream discharge measurements.

    4.3 Data Set Background Discussion
         Stream discharge measurements are critical for assessing trends 
         in streamwater acidity and other characteristics that are very  
         sensitive to streamflow differences. 

    4.4 Summary of Data Set Parameters
         Steam discharge data is calculated on one of three methods - velocity-area,
         timed filling, or neutrally buoyant object. 

5.  DATA ACQUISITION AND PROCESSING METHODS

         5.1.2 Sample Collection Methods Summary
