“When pigs fly and hell freezes over,
When elephants rumble on the ocean floor, and trained bears twirl and twirl some more
When purple kitties jump and fly, and 50 foot mice touch the sky,
When fish are talking and snakes are walking,
Then about working with the NHD I’ll consider talking”If Jeff paid his way AND got him courtside Final Four Tickets,
he would attend
Rick, in response to Kevin Roth’s un-retirement

Why LLIDs ?
NHD already has a single stream identifier: the GNIS ID. Not universal, and tied to GNIS.
LLID = Lat-Long ID = the long/lat in Decimal Degrees of the outlet of the ‘single stream’. Can be generated automatically once you determine the single stream.
Most of our thematic data contains the LLID to reference the stream. Built in QA/QC for batch transforms.
Presents linear referenced data in terms that our bios and end-users know (RM 43.2 to RM 50.9 on the Yakima River) compared to NHD relative reach measures.
Allows reporting out as river miles on a single stream, and bios to provide data in terms that they understand. We provide hatched measures on single streams, and measures for key landmarks. Easy to compute river distance between 2 points.
Regional partners such as StreamNet use LLIDs for data management

Assigning LLIDs to NHD as events• WDFW stream data had GNIS ID and GNIS names• Match GNIS_IDs between WDFW str24 and NHD and xfer to NHD copy• Gets 90% of fish-bearing streams• Manually conflate fish streams with no GNIS_ID• Send all the little streams to Ecology (their LLIDS match NHD really well)

Consistent Physical Stream Attributes• NetMap / NetTrace: Dan Miller, Lee Benda (ex-UW geomorphologists)
http://earthsystems.net/• State of the art geomorphology and hydrology. • NetTrace: DEM derived gradients, bankful width, valley width, upstream contributing
area, mean annual flow.• NetMap: Erosion / sediment delivery models, habitat suitability models (Intrinsic
Potential), wood accumulation• Currently being used for watershed characterization, fish distribution logistic regression
models, and GRTS sampling designs.

The NHD Application Demo
Originally presented in December 2010 to the State of Washington’s Geographic Information Technology Board, a subcommittee of the State of Washington Information Services Board that set’s state agency IT policies.
NHD adopted as the state’s framework hydrography Layer in January 2011
![Page 11: Andy Weiss: WA Dept. of Fish and Wildlife Rick Jordan: WA Dept. of Ecology Arleta Agun: WA Dept. of Fish and Wildlife](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649d9e5503460f94a88b87/html5/thumbnails/11.jpg)
GoalsShow the multi-agency hydrographic datasets now registered
to the NHD in the Lower Skagit.Demonstrate the power of the NHD data model, networking
capabilities, events, and shared applications.Perform a variety of analytic tasks on these integrated and
coincident hydrographic datasets.

Dirty Laundry: WDFW, WDNR, and WECY all use and maintain different hydro linework.
