1 MAPPING ALASKA S WATERS NHD Advisory Team Call December, K a c y K r i e ge r kacy.krieger@uaa.alaska.edu Alaska Hydrography Coordinator

2 ALASKA S WATER > 3,000,000 Mapped Lakes and Ponds > 847,000 Length of Mapped Streams and Rivers in miles 47,000 Length of Mapped Coastline in miles 1,980 Length of the longest river, the Yukon, in miles 616 Named Glaciers 40% Share of the Nation s Surface Water 2

3 HYDROGRAPHY CHALLENGES IN ALASKA Rapidly Changing Coastline Complex Channels Extreme Tidal Ranges Remote Locations Expansive Wetlands Disconnected Networks 3

4 History of Hydrography in Alaska NHD in Alaska began approximately 15 years ago Primarily using 50 year old data from original USGS Topos NHD at 1:63,360 scaled Multiple partners provided data to USGS Divergence of the datasets since NHD adoption in Alaska since then has been modest Agencies maintained their own hydrography data until recently Authoritative NHD dataset remained mostly unchanged. 4

11 Alaska Hydrography Technical Working Group Created for hydrography data and editing standard operating procedure coordination and collaboration, including outreach and communication with to the broader mapping community. Created under Alaska Climate Change Executive Roundtable (ACCER) Charter signed by ACCER Co Chairs 6 Federal agencies (BLM, NPS, NOAA, USFS, USFWS, USGS) and 4 AK State entities (ADFG, ADEC, ADNR, UA), plus invited technical advisors 11

13 AHTWG Coordination to Date AHTWG meeting monthly since May, 2013, now meeting quarterly Several Focus Groups meeting regularly NHDPlus Data Model Standards Data Editing Standards Communications Group has already resulted in enhanced coordination between agencies Data contributions: ADNR and TNC have uncaptured data updates Common editing standards: Creation, implementation, outreach and revision Enhanced coordination with USGS: Establish monthly USGS NHD/AK Hydro technical call Common way forward: Agreement to use AK Hydro to update the NHD in Alaska where available 13

14 National LCC Grant LCC/Fish Habitat Partnership/AHTWG/USGS NHD/ACSC Alaska hydrography mapping project funded for $300k Funds moved to University of Alaska for positions AK Hydro Program Coordinator Hired (UAA) AK Hydro Technical Steward funding continued (UAS) Funds moved for on-the-ground edits and hydro updates SMUMN - Arctic TEONs watersheds UAA Nushagak and Kvichak watersheds 14

15 AK HYDRO The Alaska Hydrography Database Regional collaborative databases housed and managed by the University of Alaska and funded by federal and state partners; which is used to store local attributes and generate updates for the NHD. Simplified workflow Basic editing requirements Elastic data model Shared update effort Centralized NHD stewardship Updating the NHD is the goal 15

16 Why AK Hydro Addresses a backlog of hydrography updates Used to store local attributes and generate updates for the NHD Ultimate goal to improve the NHD A Collaborative Database Addresses concerns with NHD in Alaska Funded by federal and state partners Located in an ArcSDE instance Housed and managed by the University of Alaska Award winning and sanctioned by the NHD 16

17 AK Hydro and the NHD Similar, but not the same Local requirements vs. national requirements Feature Classes vs. Feature Types Sharing consistent geometry Updates can go in either direction Updating the NHD is the goal 17

22 Update the NHD 22

23 Where do we begin? Digital Orthophotos Digital Planimetric Data Digital Elevation Data Digital SDMI Imagery Field Verified Reference Data Other Sources 23

24 Legacy 60-m elevation data Cutler River, Noatak NP Missing terrain and hydrology features such as rivers and lakes in legacy NED data. Missing River

25 IfSAR 5-m Elevation Data Cutler River, Noatak NP Intermap DTM includes detailed hydrology and terrain features.

26 IfSAR Improves Alaska Hydrography Mapping

27 IfSAR Status 27

28 Statewide Ortho-imagery 28

29 Where are we today? ADEC: Impaired waters, NHDPlus ADFG: Anadromous Waters Catalog ADNR: Navigable waters ADOT: Pilot project in Port Clarence BLM: updating NHD in NPR-A EPA: NHDPlus Kenai Watershed Forum: Updated NHD streams on Kenai Peninsula, will begin updating lakes and 2D features NOAA: Coastlines, bathymetric surveys NPS: Completed Denali NPP, Cape Krusenstern and Bering Land Bridge NP. Will begin Glacier Bay NPP and other lands soon. The Nature Conservancy: SW Alaska and Mat-Su Basin USFWS: On and off refuge USFS: Tongass and Chugach NF USGS: Glaciers, US Topo areas, fix NHD data model errors prior to agency/ak Hydro editing, and research into elevation derived streams from LiDAR and new 5-meter IfSAR data 29
