Data Quality Information:
Lineage:

Process step:
Generated point events for each tenth of a mile based on the start and end measures of the LLID. Routed the results along the 1:00K streams layer. Spatially joined to HUC4 polygons, and lakes polygons to acquire their attributes. Added fields INCLUDE and ONLAKE.
