Used 1-mile x 1-mile countywide grid to inspect the wtr_bodies feature class for missing and out-dated features, based on 2010 NAIP imagery (both CIR and color were used). Because the NAIP imagery was flown during the summer, county contours and older imagery was used to verify questionable features. Water bodies that showed up in the imagery but not in the wtr_bodies feature class were added by digitizing their boundaries. Some features in wtr_bodies no longer show up in the NAIP imagery and were deleted. Rationale To update the feature class.

Type of water body
Napa Co PBES
Identified as a large, inland, open body of water. Size > 1 Hectare.
Napa Co PBES
Identified as a small open body of water occurring year round with clear and obvious evidence of agricultural processes around or within the feature mainly focused on irrigation or holding but including machinery/piping and levy/raised bank. Can include aerators.
Napa Co PBES
Identified as a small open body of water occurring year round with lack of clear and obvious evidence of agricultural activities.
Napa Co PBES
Identified as an open body of water connecting lagoons and/or bays. Thin or long stretching channels that could be manmade or natural. Must occur in tidal areas.
Napa Co PBES
Identified as large and shallow body of water located inland but with an obvious connection to the bay. Must be saltwater and have obvious tidal influence.
Napa Co PBES
Identified as a shallow body with clear vegetation and not obvious boundaries of open water. Must have tidal influence and connection to a bay.
Napa Co PBES
Identified as ponds or pools associated with industrial or commercial uses, wineries included. No obvious connection to agricultural activities other than water treatment. Small groups of raised ponds with obvious aerators and fencing are more likely to be considered treatment ponds than holding or irrigation ponds.
