1.2 Description

1.2.1 Abstract: An Arc/Info coverage was prepared containing the watershed boundaries of major lakes and ponds and the remaining large riverine watersheds within the St. Lawrence River Drainage Basin located in northern New York State for the New York State Adirondack Park Agency (APA). Watersheds were delineated for the ponded waters listed by the New York State Department of Environmental Conservation (DEC) Biological Survey Unit and the Adirondack Lakes Survey Corporation (ALSC). Watershed boundaries were delineated using the most current 1:24000 and 1:25000 scale USGS topographic maps. Boundary lines reflecting the area flowing directly through the pour point of the watershed and not through a tributary watershed were drawn on the maps by hand by two independent parties. The maps were inspected, and disagreements between the parties were rectified by a third party, and the watershed lines on each individual map were digitized. The individual maps were edge‑matched and joined into a single map dataset and line and polygon topology was created. Fields were added for the polygon names (ALSC pond number or a descriptive name), polygon identification, polygon flow direction, and corresponding USGS-SCS 11-digit watershed codes. The direction of flow was determined for each polygon, and the number of the receiving polygon was added to the polygon database. This information was used to create regional watershed topology (the immediate area as described above plus the area of all tributary watersheds). Finally, an item was added to the polygon database to indicate the type of polygon drainage (i = isolated/internally draining, p = pond, r = river polygon, and a polygon number indicated the receiving pond where there was more than one direction of drainage).

1.2.2 Purpose: This digital map was intended for use in determining the area included in the surface drainage of ALSC ponded waters. Used as an overlay on other datasets to characterize watershed attributes, and for attribution of water quality data associated with ponded waters or riverine systems.

1.2.3 Supplemental Information: The data set was hand digitized using PC Arc/Info 3.4D+ by the Remote Sensing Laboratory at Plattsburgh State University (RSL) from paper original United States Geological Survey (USGS) maps. Maximum allowable RMS error was 0.003, snapdistance 20.0 meters, snaptype closest, weed tolerance 3.0 meters, and a fuzzy tolerance of 1.219 meters. Hard copies of the coverage at 1:24000 or 1:25000 scale showing arcs and dangle nodes were carefully checked against the topographic manuscript for digitizing accuracy by three individuals. DEC pond number attributes were obtained by intersecting the polygon coverage with a point coverage derived from the Adirondack Lakes Survey Corporation database with NY DEC Biological Survey pond centroid coordinates. The coverage was transferred to the New York State, Executive Department, Adirondack Park Agency (NYS APA) running Arc/Info version 8.0. Polygon boundaries and pond labels were verified, region topology was created for watersheds consisting of multiple polygons, and additional attributes were added.

2 Data Quality Information

2.1 Attribute Accuracy

2.1.1 Attribute Accuracy Report: Polygon attributes consist of the DEC ALSC pond number, UTM coordinates of the pond centroid, THIS#, FLOWTO#, USGS-SCS 11-digit watershed code number, and CLASS. All polygon attributes were visually checked on screen against aerial photos and topographic maps, and with 1:105000-scale check plots. Region attributes for region subclass WSHED consist of the DEC ALSC pond number, USGS-SCS 11-digit watershed code number, drainage CLASS, the number of subwatersheds contained within the region, the pond polygon number (THIS#), and the polygon to which it drains (FLOWTO#).

2.1.2 Quantitative Attribute Accuracy Assessment

2.1.2.1 Attribute Accuracy Value: unknown

2.1.2.2 Attribute Accuracy Explanation: All feature attributes are believed to be correct.

2.2 Logical Consistency Report:

POND, APA number (THIS#), USGS-SCS, and User‑ID attributes in polygon and region attribute tables were checked for logical consistency using ArcPlot to logically select and display and polygons. Arc/Info macros were written to create watershed regions from multiple polygons using FLOWTO# and THIS# attributes.

2.3 Completeness Report:

Extensive quality assurance/quality control measures were taken for all steps of dataset creation. It is expected however, that because of the hierarchical nature of the subwatersheds and their representation in the region data model, mistakes may be present in the nesting of the watersheds. Identifiable errors will be corrected periodically or as needed.

2.4 Positional Accuracy

2.4.1 Horizontal Positional Accuracy

2.4.1.1 Horizontal Positional Accuracy Report:

Maximum allowable RMS error was 0.003 for each digitizing session. An attempt was made to have horizontal accuracy correct to plus or minus one pencil width (about 12 meters at 1:24000) from the topographic map watershed delineations.

2.4.1.2.2 Horizontal Positional Accuracy Explanation: No formal assessment conducted

2.4.2.1 Vertical Positional Accuracy Report:

1:24000 scale and 1:25000 scale USGS topographic standards.

2.5.2 Process Step

2.5.2.1 Process Description:

A list of identified ponds from the DEC ALSC database was made for each 7.5' quadrangle.

2.5.2 Process Step

2.5.2.1 Process Description: Ponds and river systems to be delineated were identified on the most recent 1:24000 or 1:25000 scale USGS topographic maps. Metric maps were used when available because they are more accurate. When metric 1:25000 topographic quadrangles were unavailable, 1:24000 scale English maps were used. Ponds were labeled by their unique DEC or ALSC pond numbers and rivers with a descriptive name. Watersheds were delineated by two independent delineators using two sets of identical topographic maps. Delineations were performed according to methods described in National Handbook of Recommended Methods for Water Data Acquisition, Office of Water Data Coordination, Geological Survey, Washington, D. C. (1977) starting from the outlet (pour point), following along high land peaks at the rim of the basin back to the outlet.

2.5.2 Process Step

2.5.2.1 Process Description:

The two sets of watershed delineations were reconciled by a third individual overlaying the two maps on a light table. Most differences occurred in flat areas with low topographic relief, or where the exact location of the pond outlet location was not clear. In several instances more than one outlet was present for an individual pond. Differences between the two maps were minimized using 1:24000 black and white photography, 1:40000 color infrared photography, ALSC field notes defining the location of pond inlets and outlets, and field inspections.
