ERCZO -- GIS/Map Data -- Research and Watershed GIS Boundaries -- Eel River to Rivendell -- (2004-2015)

The Eel River CZO operates on several spatial scales from a zero order hillslope to the entire Eel River on the north coast of California. Rivendell, Angelo, Sagehorn, South Fork, and Eel River GIS boundaries. GIS polygon shapefiles. All files are in geographic projection (Lat/Long) with a datum of WGS84.

The watershed boundaries are from USGS Watershed Boundary Dataset (WBD) http://nhd.usgs.gov/wbd.html. Rivendell and Angelo boundaries are created from LiDAR by the CZO. Sagehorn Ranch is a privately held, active commercial ranch with no public access. Please contact the CZO if you are interested in data from Sagehorn Ranch.

__Shapefiles__

Eel River Watershed (drainage area 9534 km^2): Entire eel river. Greatest extent of CZO research.

South Fork Eel Watershed (drainage area 1784 km^2).

Angelo Reserve Boundary (30.0 km^2): Angelo Coast Range Reserve is a University of California Natural Reserve System protected land. It is the central focus of CZO research. http://angelo.berkeley.edu

Sagehorn Ranch Boundary (21.1 km^2): Sagehorn Ranch is a private ranch with active cattle raising. The owners have allowed the CZO to place instrumentation on their lands. Access is only by explicit agreement by owners.

Rivendell Cachement (0.0076 km^2): Rivendell is a small, heavily instrumented hillslope within the Angelo Reserve. It has roughly 700 instruments deployed as of 2016. Data is online at http://sensor.berkeley.edu

加利福尼亚州北海岸的Eel River区域控制单元（CZO）在多个空间尺度上运行，从零级斜坡直至整个Eel River区域。涵盖区域包括Rivendell、Angelo、Sagehorn、South Fork和Eel River的GIS边界。所有文件均采用地理投影（经纬度）并使用WGS84作为基准面。流域边界数据来源于美国地质调查局（USGS）的流域边界数据集（WBD），可通过http://nhd.usgs.gov/wbd.html访问。Rivendell和Angelo的边界由CZO利用激光雷达技术创建。Sagehorn Ranch是一家私人拥有的活跃商业牧场，无公众进入权限。如需获取Sagehorn Ranch的数据，请联系CZO。
