Title: Lake, Reserviors and Ponds (Points): California, 2012
Contributors:- Point data
- 2012
- California. Fisheries Programs Branch
- Geological Survey (U.S.)
- California. Biogeographic Data Branch
Summary: This point shapefile is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on United States Geological Survey 7.5 arc-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as centroid points. The dataset was created for two purposes: First, to attempt to correct many inaccuracies in current GIS datasets for California waterbodies, especially regarding NAMES. Second, to provide a unique numeric ID system for the California Department of Fish and Wildlife of all digitized waterbodies in California in order to assist with fisheries and biological programs management and public fishing programs, including biological surveys, fish planting, and public fishing guides. This coverage provides an accompanying center point GIS layer for the lakes layer that was assembled by the California Department of Fish and Game. This point layer is useful for representing lake locations at small (zoomed-out) scales, labeling, etc. California Department of Fish and Game: North Central Region (Region 2) and the Biogeographic Data Branch. (2012). Lake, Reserviors and Ponds (Points): California, 2012. Available at: http://purl.stanford.edu/pt381mp4669. Points derived from fields containing coordinate values within the lakes dataset. Those values were derived from initially gaining 'centroids' using ArcGIS command tools, then editing the points as needed to place in a more central location within the lake polygons. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

Title: Lakes, Reservoirs and Ponds (Polygons): California, 2012

- Geological Survey (U.S.)
- California. Biogeographic Data Branch
Summary: This polygon shapefile is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on United States Geological Survey 7.5 arc-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as single polygons (with islands), with Latitude/Longitude coordinates of waterbody centroids and a unique numeric identifier for each. Waterbody polygons represent shorelines generally at full or near-full levels. A previous version of this dataset did not contain islands. The dataset was created for two purposes: First, to attempt to correct many inaccuracies in current GIS datasets for California waterbodies, especially regarding NAMES. Second, to provide a unique numeric ID system for the California Department of Fish and Wildlife of all digitized waterbodies in California in order to assist with fisheries and biological programs management and public fishing programs, including biological surveys, fish planting, and public fishing guides. California Department of Fish and Wildlife, 2012. Rancho Cordova CA: North Central Region (Region 2); Sacramento CA: Biogeographic Data Branch. This dataset represents a combination of 1:24,000-scale or better GIS datasets considered the best currently available. The initial sources come from DFG's fisheries programs, some of which included many Sierra Nevada lakes and ponds not represented on existing USGS maps and/or not known to exist in digitized format elsewhere. Unique ID's in the field DFGLAKEID reflect the LAKE_ID in FPB_Lakes shapefile in about 22,400 cases. Many errors (attribute and spatial) existed in all the contributing datasets, and many (but not all) have been remedied here. Lake name errors were addressed to the greatest extent, spatial representation errors to a lesser extent. USGS National Hydrography Dataset (NHD) High Resolution 'waterbody' polygons were used to replace some existing polygons. It was not used exclusively however, due in part to existing errors within the NHD datasets to date, the lack of completeness for CA and the lack of time on the editors end to incorporate NHD in cases where NHD polygon representation is better than what exists here. It is the intent that NHD polygons will be incorporated more as they get updated. This layer is presented in the WGS84 coordinate system for web display purposes.

Title: BOEM Wind Planning Areas, Atlantic Region, 2013
Contributors:- Polygon data
- 2013
Summary: This polygon shapefile represents the most recent changes for the Bureau of Ocean Energy Management (BOEM) Wind Development Planning Areas in the Atlantic. Wind Planning Areas in this layer represent up to six different types of announcements within the US Federal Register that can be used to show the current status of an area that is being considered for Wind Power Development. The Smart from the Start Wind Energy Areas (WEAs) are represented in a separate layer. Not all areas will start out as WEAs. Since the WEAs were the first announcement for some of these areas, we have decided to repost the WEA layer to show its original areas prior to any reshaping by BOEM after the original announcement since the reshaped areas are really not the WEAs but one of the other six types of areas represented here. For those areas that started out as WEAs, the user may see the changes that have taken place over time. For the areas represented here, once an area has changed from one type of area to another, it will be replaced entirely by the new area. The types of areas and their descriptions can be found in the attributes section of the metadata record. To let those that are interested in Wind Energy Planning and Development know of the most recent updates to areas of interest for Wind Energy Development off the United States Coast within Federal Waters.
