Query FWA lake polygons that intersect habitat streams

Returns lake polygons from whse_basemapping.fwa_lakes_poly that share a waterbody_key with the input streams. Use with fly_trim_habitat() to fill gaps where lakes interrupt the stream network.

Usage

fly_query_lakes(conn, streams_sf)

Arguments

conn

A DBI connection to a bcfishpass database.

streams_sf

An sf linestring — habitat streams (e.g. from fly_query_habitat()).

Value

An sf polygon object in WGS84 (EPSG:4326), or NULL if no waterbody keys are found.
