+## vx.x.x.x - 2024-05-16 - [PR#1159](https://github.com/NOAA-OWP/inundation-mapping/pull/1159)
+
+This PR addresses issue #1132 and include the following changes on `tools/generate_nws_lid.py` for updating `nws_lid.gpkg` dataset.
+
+In this revised version, stations only from these two groups are retrieved:
+- lid stations with `rfc_forecast_point= True` 
+- lid stations in `/data/inputs/ahp_sites/evaluated_ahps_sites.csv`
+
+The lid stations in AK (Alaska), HI, and PR, with above two criteria have also been selected, as shown in the map below. In the previous version of the code, **all of lid stations** in PR and HI (regardless of meeting above two criteria), were also being retrieved. I have updated this version to exclude such stations. 
+
+Also, In this revised version, I've eliminated the code sections that previously generated the "is_headwater" and "is_colocated" columns, which are not needed in FIM4. Therefore, in this updated version, these columns are no longer present. 
+
+Similar to 'usgs_gages.gpkg' dataset, all lid stations, including those in Alaska, are stored in a single gpkg file (`nws_lid.gpkg`) with EPSG=5070. The Alaska stations can be identified using their HUC8 numbers (beginning with '19').
