Hydraulic Models and Supplementary Data for Selected Stream Crossing Sites in the Squannacook River Basin, North-Central Massachusetts

This data release contains links to two child items containing hydrology and hydraulic modeling data and supplemental geospatial data for selected stream crossing sites in the Squannacook River Basin in north-central Massachusetts.
 
The child item named “Hydraulic model data for selected stream crossing sites in the Squannacook River Basin, North-Central Massachusetts” contains U.S. Army Corps of Engineers’ Hydrologic Engineering Center River Analysis System (HEC-RAS) hydraulic model files along with field survey data associated with each stream crossing location. This data release also includes a data dictionary defining culvert designs, site locations, modeled flows and water surface elevations, and aquatic habitat and stream connectivity restoration potential.
 
The child item named “Spatial Data Layers for Selected Stream Crossing Sites in the Squannacook River Basin, North-Central Massachusetts” contains geospatial data files of stream cross sections, stream centerlines, stream bank lines, and stream crossing location points used as input for hydraulic models.

Additionally, these preliminary culvert designs and associated selected data are hosted on the U.S. Geological Survey StreamStats web application (https://streamstats.usgs.gov/ss/) for Massachusetts.
