IP workshop, Portland, November 19-20:

Notes from Day 1 presentations

IP Technical Considerations

Phone attendees: Cedric Cooney, Jamie Glasgow, Martina Koller

NOTE: During the NetMap presentation, there was great interest by the group in using the collaborative functions being developed on the NetMap site to help researchers begin to document important thresholds and physical and biological break points. The program allows users to test different weights/curves currently, and output those models to for colleagues. The group proposed finding a way to , internally support some minimal documentation of test runs, thoughts on additional curves, data points, and thresholds used (this goes for fish and non-fish variables – land use, roads and other examples were used). This might be highlighted as a future action item.

Presentations:

Day 1: State of the IP 2008 - presentation by Mindi Sheer

Day 1: Modeling Intrinsic Potential for Steelhead and Coho Salmon - presentation by Kelly Burnett

Day 1: Development and implementation of IP models, and their integration with watershed and land-use attributes - presentation of Netmap from Lee Benda

Questions on Presentations

1)Intrinsic Potential Data and Analyses

K. Burnett (USFS)

  1. Are there IP models for resident salmon in region?
  1. Resident group was scheduled for tomorrow, most were bulltrout experts and many could not attend due to a conflicting meeting.

2)State of the IP 2008 - PNW data and applications

M. Sheer (NOAA), E. Gilbert (ODFW), S. Busch (NOAA)

  1. Did you compare NHD segments, difference in the gradients?
  1. Used Netstream
  1. Management perspective - use of IP models versus direct field observations?
  1. Models are about historical habitat and where there are inaccessible habitats; places where there is no direct field observation possible. IP can give a regional view.

3)The NHD and DEM derived streams - Comparison and Discussion

Bill Kaiser (USFS), D. Wickwire (BLM)

Q.Any thoughts to improve the obvious stream discrepancies in dataset?

  1. Yes, trying to work with partner agencies, work with people here, initiate LIDAR projects. Hope to resolve in next few years - want it done in a sound hydrological manner
  1. What are the differences in linework in NHD and DEM-derived stream?
  1. NHD is derived from partners, USGS maps converted to DLG vectors; then agencies started using their own techniques to update these so there is a lot of variety now. There will be similarity (good correlation) in linework between the two types of stream layers in streams that have a moderate to high degree of slope. Less slope = greater variance.

Notes from talk (no powerpoint presentation available)

  • PNW Hydrography Framework Group - Bill and Dan regional data stewards for watershed boundary dataset and regional hydrography dataset. More detail at the workshop in the afternoon of day 1
  • Here to learn about practitioner needs and how they can help meet those needs
  • Watershed Boundary Dataset available on website
  • NHD and WBD datasets to be integrated in a single geo-database
  • Projects - pilot LIDAR project on generating streams
  • West side of Cascades streams are derived by contours which are not accurate - LIDAR will has the ability to penetrate tree canopies and will provide better accuracy.
  • Work with hydrologists on stream initiation thresholds
  • Useful data links referenced during the presentation
  • NHD and NHD Plus
  • NHD portal:
  • NHD Plus:
  • Pacific Northwest Hydrography Framework
  • PNW portal:
  • Watershed Boundary Dataset of Oregon and Washington:
  • NRCS – Watershed Boundary Dataset (WBD):
  • StreamStats
  • Oregon:
  • Washington:
  • LiDAR
  • Puget Sound LiDAR Consortium:
  • Oregon LiDAR Consortium:

4)Development and implementation of IP models, and their integration with watershed and land-use attributes

L. Benda and D. Miller (EarthSystems Institute)

NetMapresources: (link to brochure; journal article)

Q. Is this tool useful in heavily impacted areas, specifically in agricultural and urban development areas?

A. Haven’t been used in that way, but could potentially be used to look at ag and urban development. Higher resolution topographic data would be better. System is not fixed - user can create what he wants to see

Q. How does stream temperature tool work?

A. Need basic scale temperature models. There is a USGS model (Stream Temp), but you need data to run the model. NetMap has created an additional model - calculates thermal load with full stand of trees, then recalculates without trees; produces map to determine differences. New tool for NetMap and would like to make it more complex.

Q.Does tool deal with groundwater?

A. None explicitly at the moment. Some crude analyses -look at tributary confluences and valley width constraints. There is interest in this with the WildSalmonCenter project in Russia where ground water upwelling is an issue. If a potential user wanted to see this option, they could start dialog to bring those tools in.

Q. Is there a mechanism for archiving and sharing thresholds for later use?

A. Users can save threshold settings and share. Because tool is user defined, there is probably a lot of variation in thresholds. This sort of conversation should be taken to the forum on the website. Need to archive the metadata of the model, especially when in flux. Needs to be built into resulting dataset, so it can’t be lost.. Standards for evaluating a curve or model - one person review, forum of experts, etc (are there?). Published models are indicated in the tool, and user can make their own or add items

Q. In looking at lateral areas per reach, how do you deal dealing with thresholds set by agencies at a different scale?

A. Tools look at finer scale information have not been used yet, but groups want more detailed information. For example, Shasta Trinity looking to improve ERA (Equivalent Roaded Area).

Q. When tool is released, will there be a workshop or training?

A. Have been offering informal training sessions for groups that want one. Tentatively will host a session in Fall 2009 in Washington. All tools have a help section - looking for feedback on the help section.PNAMP would be happy to help with this.

Q.Cost associated with NetMap for users

A. No.
