Elk River - Monitoring and Landslides

<div style='text-align: left;'> <span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'>This map displays turbidity monitoring stations and cross sections in the Elk River watershed. Overlaid are geology and landslide data from the California Geological Survey and historical maps from NOAA. The purpose of the map is to show the location of monitoring stations where there is a high risk of landslides or there has been an occurrence of landslides.This map is featured in the <a href='https://www.waterboards.ca.gov/resources/data_databases/wq_status_report.html' rel='nofollow ugc' target='_blank'>2019 Water Quality Status Report</a>. <br /></span></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'><br /></span></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'> <span style='font-weight: bold;'>Data sources</span>: </span></span><br /><span style='color: rgb(0, 0, 0);'><span style='color: rgb(0, 0, 0);'><span style='color: rgb(0, 0, 0);'>Monitoring stations and cross sections - North Coast Regional Water Quality Control Board</span></span></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><a href='https://spatialservices.conservation.ca.gov/arcgis/rest/services/CGS/GeologicMapCA/MapServer/21' rel='nofollow ugc' target='_blank'>Generalized Rock Types</a> - CA Department of Conservation (California Geological Survey)</span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><a href='https://spatialservices.conservation.ca.gov/arcgis/rest/services/CGS/MS58_LandslideSusceptibility_Classes/MapServer' rel='nofollow ugc' target='_blank'>Landslide Susceptibility</a> - CA Department of Conservation (California Geological Survey)<br /></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><a href='https://spatialservices.conservation.ca.gov/arcgis/rest/services/CGS/LandslideInventory_DC1_Older/MapServer/' rel='nofollow ugc' target='_blank'>Landslide Inventory (Older)</a> - CA Department of Conservation (California Geological Survey)</span><br /><span style='color: rgb(0, 0, 0);'><span style='color: rgb(0, 0, 0);'><a href='https://spatialservices.conservation.ca.gov/arcgis/rest/services/CGS/LandslideInventory_DC1_Younger/MapServer' rel='nofollow ugc' target='_blank'>Landslide Inventory (Younger)</a> - CA Department of Conservation (California Geological Survey)</span></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><span style='color: rgb(0, 0, 0);'>Historical maps (1916-1969) - National Oceanic and Atmospheric Administration (NOAA)</span></span></div><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><span style='color: rgb(0, 0, 0);'>NHDPlus Flowlines and watershed boundary - U.S. Geological Survey</span></span></div><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'></span></span><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'></span></span><span style='font-weight: bold;'></span></span></span><div style='text-align: left;'><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'><br /></span></span></div><div style='text-align: left;'><div><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'><span style='font-weight:bold;'>Created by: </span><br />Lance Le<br />North Coast Regional Water Quality Control Board<br />[e-mail]</span></span></div><span style='color: rgb(0, 0, 0);'><span style='background-color: rgb(255, 255, 255);'><br /><span style='font-weight:bold;'>Maintained by: </span><br />Michelle Tang<br />Surface Water Ambient Monitoring Program (SWAMP)<br />State Water Resources Control Board<br />[e-mail]<br /><span style='font-weight:bold;'><br />Disclaimer &amp; Access Use Constraints:</span><br />This data may change at any time and should
