California Department of Water Resources (DWR) 20150107 vector digital data http://bios.dfg.ca.gov/ ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/1000_1099/ds1099.zip From June 9 thru June 13, 2014 the Feather River was surveyed for bank swallow breeding populations. This survey was conducted by Oroville Field Division, Northern Region, and Division of Environmental Services staff. The bank swallow (Riparia riparia) is listed as a threatened species under the California Endangered Species Act (CESA). Historical surveys of Feather River populations were completed in 1987 and 1988 by the California Department of Fish & Game (DFG). In 2002 and 2003 Department of Water Resources staff conducted bank swallow surveys under the Federal Energy Regulatory Commission (FERC) Relicensing of Oroville Dam. The data from these surveys is analyzed in Study Plans SP-T1: Effects of Project Operations and Features on Wildlife and Wildlife Habitat, and SP-T2 Project Effects on Special Status Wildlife Species. In response to the report findings DWR and DFG consulted on the Feather River bank swallow populations and from this consultation a conservation easement of JEM Farms was acquired. JEM Farms is located at river mile 44-45 and contains walnut orchards adjacent to the Feather River channel. The banks of this site are vertical and erodible and therefore highly favorable for bank swallow habitat protection. The Feather River system was surveyed in June 2009 as part of our JEM Farms Easement agreement. In order to have an understanding of how well this conservation site is functioning we needed to know what the overall Feather River bank swallow population is. No population surveys on the Feather River had been completed since 2003. In coordination with CDFW and the United States Fish & Wildlife Service (USFWS) staff from the Oroville Field Division, Northern Region and Division of Environmental Services surveyed the Feather River from River Mile 59 (at Thermalito Afterbay Outlet) to the mouth.

Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.3.1.4959 A geodatabase was constructed to contain the relevant data to accomodate the field survey. The geodatabase contained a feature class with associated domains to define the field entries for the Bank Swallow observations. A feature class of river miles was also created to provide a measured reference system for locations of bank swallow colonies. The use of aerial photography was very important to the success of the suvey and to supplement the data collection. Using a jet boat, a laptop computer running ArcMap, and a USB GPS receiver, the field crew was able to locate themselves in the field on the aerials with the use of the GPS. The GPS allowed us to define a start and end point of the bank swallow colony. The bank swallow colony was then digitized over the 2005 NAIP imagery. Since the aerials were 3 years old there have been some geomorphologial changes to the river since they were taken. Some interpretation of the bank delineations had to be made in the field to capture the true colony location.

Esri Sequential unique whole numbers that are automatically generated. Shape Feature geometry. Esri Coordinates defining the features. Obs_Date Date of observation. Year Year of observation. Obs_Time Time of observation. Colony_ID Unique ID for colony based on approximate river mile of colony location. Active_Col Query: Is the colony active or inactive? Response: Y=Yes or N=No Present Query: Are bank swallows present? Response: Y=Yes or N=No Burrow_Avg The average burrow count. (Used CDFW protocols where two observers tallied all burrows observed at the colony and then compared counts. If counts were within 10% of each other than the counts were averaged together to obtain this estimate.) Remarks Notes, thoughts or data not recorded in other fields. VegAB Dominant vegetation type on bank in relation to the colony. VegOB Dominant vegetation behind bank in relation to the colony. River_Mile Approximate river mile of colony location based on center of colony. River_Bank Heading downstream either right or left bank. Bank_Height Bank height estimated in field based on meters.
