iUTAH GAMUT Synoptic Sampling Site Sub-watershed delineations

This dataset includes sub-watershed delineations created for ~66 stream sites across the three iUTAH GAMUT watersheds, Logan River, Red Butte Creek, and Provo River (including GAMUT Aquatic stations: gamut.iutahepscor.org ), where monthly water quality samples were collected 2013-2014. Sub-watershed delineations will allow for analysis of the landscape contributing to these sites, which can then be used in models of water quality for the stream sites. This will contribute to the iUTAH goal of modeling the impact of land-use changes on in-stream water quality.

Delineations were generated from 10 m DEMs (Utah GIS portal) using ArcMap tools: mosiac, fill, flow direction, flow accumulation, snap pour point, watershed and raster to polygon. Default settings were used for all tools.
