Hydrology Line Features, Modoc NWR

Citation

Hydrology Line Features, Modoc NWR, 2013, U.S. Fish and Wildlife Service, Pacific Southwest Region, Inventory and Monitoring Program

Summary

The Hydrology Line Feature Class defines linear hydrographic features on RSL and in the region of hydrologic influence (RHI). The line feature class is composed of NHD Plus streams outside of the refuge borders in the region of hydrologic influence (RHI) and more detailed digitzed canals, ditches and streams on RSL based off 2010 National Agriculture Imagery Program (NAIP) 10 meter aerial imagery.

Material Request Instructions

Outside the Refuge in the region of hydrologic influence (RHI) the hydro_ln data was taken from the National Hydrography Dataset (NHD) Plus.  The major streams were extracted from NHD Plus using a Strahler stream order greater than two and were clipped to the RHI, defined by a watershed delineation just downstream of the refuge using U.S. Geologic Survey's Streamstats online delineation tool.  Inside refuge borders the Hydro_ln feature class is represented by digitized streams, ditches and canals.  The digitization was done using National Agriculture Inventory Program's 2010 aerial imagery and a georectified image of an old irrigation map found in the basement at the refuge.

Purpose

This line feature class is intended to represent streams, ditches, and canals on Refuge Service Lands (RSL) and streams in the Refuge's region of hydrologic influence (RHI)
