Description:

Abstract:

A delineation of the watersheds of all named streams and all ponds identified by a Department of Environmental Conservation pond number within the larger watershed of the Ausable and Boquet Rivers in the Adirondack Park.

Purpose:

The data was developed to assist state and town governments, as well as lake managers in assessing and protecting water quality by providing information about the source of the water in each water body.

Process_Description:

The original subcatchment lines were drawn on 1:24000 and 1:25000 quad maps, then traced onto sheets of mylar. A series of 6-8 tick marks depicting UTM coordinates were added to the mylar. The mylar sheets were scanned and the image was saved in a TIF format. The TIF image was added to ArcMap. Pyramids were built for the raster data set. The raster data was georeferenced using the tick marks as control points. The table of georeferenced points was saved as a text file. ArcScan was used to vectorize the raster data using the following settings: Intersection Solution: Median Maximum Line Width: 20 Compression Tolerance: .025 Smoothing Weight: 3 Gap Closure Tolerance: 100 Fan Angle: 45 Hole Size: 0 The new vector data was added as a feature class in line form to the geodatabase. Noise and tick marks were deleted. Each line was checked against existing topo and quad layers and corrections were made in an ArcScan editing session. A new polygon feature dataset was created from the line feature class. The symbology was changed to display a unique value for each polygon and the polygons were checked to ensure that they were all closed. Attributes were added to the table. OID was automatically assigned by the program, length and area were automatically calculated by the program, This#=OID, class was visually checked, I was assigned if no outlet was visible on aerial photos, POND is the DEC pond number for ponds or a user assigned alphanumeric code for streams and rivers with smaller numbers reflecting more downstream locations (Example: AUS000 is the main channel of the Ausable River, AUS010 is the first named tributary to the Ausable as you move upstream from its mouth). NSUBS is the number of polygons which drain through that polygon. (For headwater streams or ponds, NSUBS is 1). FLOWTO is the OID of the polygon which that polygon drains directly into. (For isolated ponds, FLOWTO is surmised from topography information.) Watershed sub-basins were created from the subcatchment polygons using the following AML: \\apaappserver\ApaGis$\MasterData\Watersheds\24k\macros ( file://\apaappserver$24k) Sub-basins were then merged into basins.
