This layer is a snapshot of stream gages from the fall of 2020. It is the product of an attempt to compile a comprehensive, geospatial list of long-term stream gages whose data is publicly available. Initially, the layer will consist of USGS and CDEC gages. Over time, local (county, municipal, etc.) gages will be added. This layer is not claimed to be authoritative. In cases where this layer and the data maintained by the source entity differ, this layer always defers to the source entity. For analysis purposes, the gage point locations have been altered by SWRCB to coincide with the corresponding line features in the National Hydrography Dataset (NHD) Medium Resolution. The original point locations can be found "x" and "y" fields of the layer's attribute table.<div><br /></div><div><div>For questions, contact the SWRCB Division of Water Rights: <span style='color:rgb(32, 33, 36); font-family:Roboto, arial, sans-serif; font-size:16px;'>DWR@waterboards.</span><span style='color:rgb(32, 33, 36); font-family:Roboto, arial, sans-serif; font-size:16px;'>ca</span><span style='color:rgb(32, 33, 36); font-family:Roboto, arial, sans-serif; font-size:16px;'>.gov.</span></div></div><div><span style='color:rgb(32, 33, 36); font-family:Roboto, arial, sans-serif; font-size:16px;'><br /></span></div><div><span style='color:rgb(32, 33, 36); font-family:Roboto, arial, sans-serif; font-size:16px;'><b>Data dictionary:</b></span></div><div><table border='0' cellpadding='0' cellspacing='0' style='border-collapse:

This layer is not claimed to be authoritative. In cases where this layer and the data maintained by the source entity differ, this layer always defers to the source entity. This layer joins existing data from various sources along with newly-created data. Many of the attribute fields were populated using geoprocessing tools, and while post-processing spot checks were performed, the large number of features precludes complete data verification. Therefore, the data can be used to identify large trends, but where accuracy of individual site data is crucial, the data should be verified by viewing the source data. |
