For the weeks of May 20 and 28 the BLM, FS and REO hosted a series of
workshops with agency hydrologists in order to establish a single set of
hydrography for 49 high priority Sub-basins.
These 4th Level HUC’s covered portions of Oregon and
Washington. With the very high level of
support from the hydrologists (staying until 10 at night!) we were able to meet
our goal in agreeing on which agency hydrography to use.
The REO has compiled the results of the workshops and developed a jpg
file for you to view. Click here

Our next step in this process is to task a contractor to combine the
different agency’s hydrography data, according to the guidelines from the
workshops, into a single dataset. For
this first phase the contractor will not edgematch or route. This first step is simply to integrate
hydrography and verify against the workshop guidelines. We expect to start this contract the week of
June 10, and finish in early July. The
following task order will focus on creating a seamless dataset and routing this
so that agency data can be reattached.
Our final goal is to submit this to the USGS national database, as well
as load this into the NW Framework Hydrography Clearinghouse (hydro.reo.gov). Since these workshops were so successful we plan on hosting
another set of workshops this fall to finish the sub-basins for Oregon and
Washington.
