2 · USGS WaterData — Monitoring Stations & Parameters

Reads the watershed boundaries from notebook 1, discovers the USGS monitoring stations inside them via the new USGS Water Data API, and records which priority parameters each station measured.

Step 5 — Discover monitoring stations

We load the watershed boundaries saved by notebook 1, ask the Water Data API for every station in their bounding box, then keep only those that fall within the watershed polygons (a spatial join).

Show code 
boundaries_path = S.data_dir / "spatial" / "huc8_watersheds.parquet"
if not boundaries_path.exists():
    raise FileNotFoundError(
        f"{boundaries_path} not found — run notebook 1 (1_usgs_hydrofabric) first."
    )
watersheds_gdf = gpd.read_parquet(boundaries_path)
bbox = list(watersheds_gdf.total_bounds)  # [min_lon, min_lat, max_lon, max_lat]; reused below

stations_gdf, _ = waterdata.get_monitoring_locations(bbox=bbox)
stations_gdf = stations_gdf.set_crs(4326)
stations_in_area = gpd.sjoin(
    stations_gdf,
    watersheds_gdf[["huc8", "name", "geometry"]],
    predicate="within",
    how="inner",
)
print(
    f"{len(stations_gdf)} stations in the bounding box; "
    f"{len(stations_in_area)} within the watersheds."
)
save_outputs(
    stations_in_area, S.data_dir / "usgs_waterdata" / "usgs_monitoring_locations.parquet"
)

Step 6 — Which priority parameters does each station measure?

The README prioritizes these water-quality parameters, plus water-quantity (flow & level). For each we list the USGS parameter_codes (used by the time-series & field-measurement services) and the Water Quality characteristic-name patterns (used by the discrete-samples service). classify_parameter maps any measured parameter code / characteristic to its priority group (or None).

Step 7 — Map stations by priority parameter

One colored layer per priority parameter, over the watershed outlines on the topo basemap. A station that measures several parameters appears in several layers.

Interactive selector: click a legend entry to hide/show that parameter’s layer.

Show code 
PARAM_COLORS = categorical_colors(PRIORITY_NAMES)
watershed_outlines = gv.Path(watersheds_gdf).opts(color="black", line_width=1.5)

stations_param_map = gvts.EsriWorldTopo * watershed_outlines
for param in PRIORITY_NAMES:
    subset = stations_in_area[stations_in_area[param]]
    if len(subset) == 0:
        continue
    stations_param_map = stations_param_map * gv.Points(
        subset,
        vdims=["monitoring_location_name", "monitoring_location_id", "site_type"],
        label=param,
    ).opts(color=PARAM_COLORS[param], size=7, line_color="white", tools=["hover"])

stations_param_map = stations_param_map.opts(
    frame_width=800,
    data_aspect=1,
    title="Monitoring stations by priority parameter (click legend to toggle)",
    legend_position="right",
    active_tools=["wheel_zoom"],
    hooks=[make_legend_clickable],
)
stations_param_map

What’s next

The station inventory — with data-type flags and per-parameter columns — is saved to data/usgs_waterdata/. Later notebooks will fetch the actual records (daily, continuous, field measurements, samples) for these stations and parameters.
