Wernly 2022 publication n/a US Geological Survey https://doi.org/10.3133/ofr20211125 The Old Erie Canal has undergone sedimentation and aquatic growth that have restricted flow and diminished the aesthetic quality of the canal during the nearly 200 years since its construction. During 2018–2019, the U.S. Geological Survey (USGS) in cooperation with the Madison County Planning Department and the New York State Canal Corporation conducted a study of the Old Erie Canal between the Town of DeWitt, New York, and its junction with the current Erie Canal of the New York State Canal System near Rome, N.Y. The study comprised bathymetric, velocity, and water-quality surveys and documentation of the canal infrastructure. The USGS established benchmarks and staff gages along the 30.8 miles of the canal study area to reference the water-surface level in the canal to the North American Vertical Datum of 1988 (NAVD 88). Water-quality data (dissolved oxygen, water temperature, specific conductance, pH, and turbidity) were collected concurrently with the bathymetric survey (spring 2018) to characterize changes in water quality along the length of the canal. The canal infrastructure was documented to provide a baseline assessment. This dataset contains a shapefile representing water velocity observations made by an Acoustic Doppler Current Profiler (ADCP) during the 2018 survey, and includes measurements of water speed and direction along perpendicular transects of Old Erie Canal. The purpose of this study was to document the current hydrology and hydraulics of a 30.8 mile long section of the Old Erie Canal and to provide data to water resource managers and land use planners to improve the water quality and aesthetics of the canal. 2022 Publication date Complete None -76.0496740 -75.6708836 43.1162229 43.0411998 USGS Thesaurus geospatial datasets ADCP acoustic doppler current profiler hydroacoustics sea-floor characteristics hydrology geographic information systems GPS measurement USGS Metadata Identifier USGS:5f1f1fa782cef313ed8eae1c None Old Erie Canal United States New York State Madison County Oneida County Onondaga County None These points are defined for scientific research purposes and should not be used as a sole source of reference for any regulations and policy making.

The survey was conducted from April 16 to April 20, 2018 in early spring when aquatic vegetation caused a minimal amount of interference with the ADCP’s measurements. The perpendicular quality assurance data set, where boat speeds were less and nearly the full width of the canal was measured, was separated by benchmark section to determine how velocity changed down the length of the canal. Hydrodynamic measurements were collected concurrently with the bathymetry survey. Water velocity data were collected with an ADCP in the portions of the canal navigable by boat. Due to the long length and narrow width of the canal, the survey transect was run longitudinally down the centerline of the channel to measure water depth. Velocity data were not screened in RiverSurveyor beyond the steps taken with the bathymetric dataset (ADCP_Bathymetry_Points.shp) except that all flow speeds greater than 2.00 ft/s were considered erroneous and removed. Of a total of 41,656 velocity data points, 70 data points (about 0.2% of the total survey) having a mean speed greater than 2.00 ft/s were removed. Of the 70 points removed, 63 came from the longitudinal transects and 7 from the perpendicular quality assurance transects. Horizontal survey positions for the ADCP were acquired using a Satellite-Based Augmentation (SBAS) GPS receiver positioned directly above the ADCP. This unit provided a manufacturer-stated horizontal survey accuracy of less than 1.0 meter (SonTek, 2015a), however, horizontal accuracy is affected by the multipath environment (e.g. proximity to trees, buildings, or cliffs), the number of satellites in view, satellite geometry, and ionospheric activity (SonTek, 2015a). No independent testing was conducted to confirm the stated horizontal accuracy of the survey, but for the purposes of this study, the exact location of a given surveyed point in space was deemed to be less important than the relative locations among the surveyed points and the distances between adjacent points. This processing step describes the collection of hydrodynamic data during the bathymetry survey conducted by John Wernly. A SonTek RiverSurveyor M9 ADCP was mounted to the side of a small boat propelled by an outboard motor. The primary purpose for the use of the ADCP was the vertical beam to measure depth in the canal during the bathymetric survey but flow direction and velocities were also measured. The collected hydrodynamic data were used to produce two datasets of depth averaged velocities for the: 1) the primary longitudinal transects which run down the center of the canal and 2) the second set of quality assurance transects which run perpendicular to the canal’s width. These data were used to make general inferences about the canal’s hydrology. Survey points were georeferenced using a Satellite-based Augmentation GPS receiver that is a component of the ADCP. 202004 U.S. Geological Survey, Northeast Region John F Wernly Hydrologist mailing address

Cortland NY 13045 US (607) 227-4145 jwernly@usgs.gov A shapefile containing point locations of water velocity observations collected perpendicular to the flow of the canal with an ADCP was created. This process step was performed John Wernly. a) Velocity data were not screened in RiverSurveyor beyond the steps taken with the bathymetric dataset except that all flow speeds greater than 2.00 ft/s were considered erroneous and removed. Of a total of 41,656 velocity data points, 70 data points (about 0.2% of the total survey) having a mean speed greater than 2.00 ft/s were removed. Of the 70 points removed, 63 came from the longitudinal transects and 7 from the perpendicular quality assurance transects. The table was exported as WV_perp.xlsx. b) A shapefile was created in ArcMap v.10.7 from WV_perp.xlsx using the "XY Layer Event" tool. c) The resulting shapefile was projected to WGS 1984 Web Mercator Auxiliary Sphere using the "Project" tool to obtainWater_Velocity_Perpendicular_Points.shp. 20200401 Vector Point 3453 WGS 1984 Web Mercator Auxiliary Sphere (Esri Full Name: WGS_1984_Web_Mercator_Auxiliary_Sphere) 0.0 0.0 0.0 0.0 coordinate pair 0.6096 0.6096 Meter D_WGS_1984 WGS_1984 6378137.0 298.257223563 Water_Velocity_Perpendicular_Transects Table containing attribute information associated with the dataset.
