    2016 Stream Spotter Results and Information

    newSynopsis:  WAVE specimens were collected by volunteer Stream Spotters and/or Fran Martino from 13 study sites during July through September 2016.  The Izaak Walton League (IWL) rating uses the presence of various macroinvertebrate groups, combined with estimated tolerance values for these groups, to calculate an index of water quality. The IWL narrative score ranges are <11 Poor; 11-16 Fair; 17-22 Good, and 22 Excellent. There is no upper limit for the Excellent range.  Recap of findings indicate streams showed good promise, but it is important to note that sampling was done in early July before drought conditions increased.

    IWL Score Category Ranks 2016 2015 2014
    Poor 3 Sites (23%) 7 Sites (54%) 5 Sites (38.5%)
    Fair 8 Sites (62%) 2 Sites (15%) 2 Sites (15%)
    Good 2 Sites (15%) 4 Sites (31%) 5 Sites (38.5%)
    Excellent 0 Sites 0 Sites 1 Sites (8%)


    What does a Stream Spotter do?

    Stream Spotters are the “eyes of the watershed” - they keep watch on what’s going on out there and report their findings to share with others.

    Stream Spotters can do a variety of things to help watch over the Stockport Creek Watershed. Stream Spotters may look at the physical characteristics of the stream and note changes they see. Stream Spotters can measure the stream to see how wide it is and how deep it is. Some Stream Spotters may take an inventory of the aquatic vegetation they find in the stream. Others may record information about the aquatic insects found in the stream.

    Some Spotters may want to record the chemical components of the stream - how much oxygen there is, what the pH level of the water might be, or other readings. Stream Spotters may record the temperature of the water and note the weather once a week.

    Who can become a Stream Spotter?

    Anyone can! Maybe the stream runs behind your house, where you enjoy a morning cup of coffee. Perhaps your school is near the stream, or maybe you take your dog for a walk near one of the streams in the Stockport Creek Watershed. Maybe you like to go fishing at a stream, or you like to go bird-watching.

    We’ll help you learn what to look for, and provide you with training on how to use some of the equipment.

    Where do Stream Spotters do their observations?

    Stream Spotters are needed all over the watershed! We would like to have volunteers in each of the 26 municipalities in the Stockport Creek Watershed.

    About the Watershed

    Stockport Creek Watershed drains 517 square miles of the mid-Hudson Valley in parts of Columbia and Rensselaer Counties in Eastern New York, and Berkshire County in Western Massachusetts. The watershed drains the western flank of the Taconic Mountains, along the New York-Massachusetts border, and the southern edge of the Rensselaer Plateau, in Rensselaer County, to the Hudson River at Stockport, NY. The watershed is primarily forested (71%) and agricultural (21%) land with most of the agriculture focused in the lowland areas adjacent to the principal rivers in the watershed, Kinderhook and Claverack Creeks.

    Stockport Creek is formed by the confluence of the Kinderhook and Claverack in the town of Stockport, Columbia County; Kinderhook Creek drains the northern 63% of the Stockport Creek Watershed, and Claverack Creek drains the remaining 37% in the southern part of the watershed.

    Stockport Creek Watershed is the second largest tributary watershed to the tidal Hudson River. Water in all or part of twenty-six municipalities are captured by the Stockport Creek Watershed. Fifty-six percent of Columbia County, 20% of Rensselaer County, and 2% of Berkshire County drain to tide water at the mouth of Stockport Creek.
