LLID_routes is a statewide routed stream layer coincident with NHDFlowline geometry.

Hopefully the next update will at least handle the 3 LLIDs in the Columbia Basin with issues. These are good training for the new steward.: 192553462195 (wria 37 ditch) with 2 begins, LLID 1216854466006 (wria 26) assigned to 2 lines needing after Steve VanderPloeg and Cowlitz biologist's input, and 1218171459720 (wria 29) with 1 line yet a gap needing reprocessing of the NHD arcs.

2025-12-15 (updated by Leslie Sikora) to support data submitted via the NWIFC portal and the 2025-10-13 version of SWIFD. The update adds Discovery Cr (1215710468997) and 4of5 LLIDs cited in SWFID since 2023-05-15 when a steward quickly retired. At this time the 5th LLID (1223631472083) cannot be added until the routing differences in that area between geolib LLID_Routes and NHDflowline are reviewed.

2025-04-14 (updated by Leslie) to support data submitted via the NWIFC portal. Portal proposals were posted by both the NWIFC and WDFW editors.

2024-09-04 (updated (by Leslie Sikora) added new routes per proposedLLID_Routes for NWIFC SWIFD and Region 3 data needs. It also restores a few lines from older route files. It also fills the few blank .HUC8code values. Also added a .LineSourceDesc field to clarify where the source of the line geometry (and fills any that were null in the W2N_LLID_Routes20240823 file sent to NWIFD).

2023-09-07 updated (by Leslie Sikora) to truly change the Butte Cr LLID from 1176788459820 to 1176777459820 to coordinate with the LLID used by ODFW for this Oregon stream. And purged the bogus -9999 values from the SWIFD.HUC_8 field.

2023-08-21 updated (by Leslie Sikora) adding a .HUC8code field to help manage the SWIFD.HUC_8 field.

2022-04-08 updated (by Arleta Agun) updating the linework.
