NEWS
TO REPORT
Al
Rea explained the USGS 4th field boundary project to the group.
The goal of this project is to discriminate between the perennial and
intermittent streams for the entire state.
This process will involve taking all the 1:24k streams from the NHD
layer, and “burning them in” the DEM’s, based on 8-digit huc boundaries.
This is the reason they need a good, accurate 4th field
boundary – so it will match as accurately as possible.
Several
comments regarding the USGS 4th field boundary project were received
from a variety of sources, in either shapefile or .jpg format, and the TWG will
review these suggested changes during the 1/25/05 meeting.
4th FIELD HUC REVIEW
Lines
received from Gary Young, USBR – The group reviewed the comments submitted by Gary Young (in
shapefile format). Some of the
larger proposed changes were reviewed as follows:
The boundary between the Upper Henry’s and Beaver-Camas hucs was changed to include the West Dry Creek stream with the Beaver-Camas huc, and another un-named tributary that was draining to the west was put in with the Upper Henry’s huc.
A portion of the northern boundary between the Upper
Henry’s and Lower Henry’s hucs was re-drawn from Davis butte to another
un-named ridge to the southwest to more accurately reflect the topographical
features of the terrain.
A portion of the boundary between the Blackfoot
and American Falls hucs (southwest of Blackfoot) was re-drawn to more accurately
reflect the topographical features of the terrain.
A portion of the boundary on the Blackfoot huc
(where the Blackfoot, Portneuf, and Bear Lake hucs join), southwest of the
Blackfoot River, was re-drawn to
more accurately reflect the topographical features of the terrain.
The northern portion of the 4th field boundary between the Salmon Falls and Upper Snake-Rock huc will be moved east to more accurately reflect the topographical features of the terrain. This line will be sent to Erv Cowley, BLM for collaboration, because Erv has done extensive work on the Salmon Falls huc. Gary Young re-delineated this line and is confident of this change, stating that is was very difficult to tell which way the drainage was going near the town of Rogerson, and either set of linework (Erv's or Gary's) would work in that area. Once past the town of Rogerson, the ridgelines are easier to follow.
The portion of line between the
Goose Creek and Upper Snake Rock hucs that previously included Big Cottonwood
Creek has been moved to put this drainage in with the Upper Snake Rock huc.
Gary Young noted this change, and Valdon Hancock, with the Sawtooth
National Forest, had already completed the linework.
This line will be incorporated into the USGS 4th field
boundaries, as well as the draft master watershed coverage.
There were several additional smaller changes
identified by Gary Young. These
boundary changes will be reviewed and incorporated where necessary into the USGS
4th fields, and eventually added into the draft master watershed
coverage.
Lines and
.jpg files received from Sue White, Clearwater National Forest: The group reviewed these changes, and the following
recommendations were made:
The line at the southern end of the Clearwater huc (Winchester.jpg) was
redrawn to more accurately reflect the topographical features of the terrain.
The 4th field boundary between the Clearwater, South Fork
Clearwater, and Middle Fork Clearwater hucs, in the South Fork Clearwater huc,
at the Clearwater/South Fork Clearwater river confluence was redrawn to exclude
a small stream west of the confluence, and also to include the multiple outlet
point.
There were several additional smaller changes identified by Sue White.
These boundary changes will be reviewed and incorporated where necessary
into the USGS 4th fields, and eventually added into the draft master
watershed coverage.
Lines
received from Genna Ashley-Poulson, IDWR: The
group reviewed these changes, and the following recommendations were made:
The digitized line at the southern portion of the Clearwater huc will be
incorporated.
The concept lines from BLM were digitized by IDWR and made 24k compliant.
There was a question regarding Seaman's Creek.
From the DRG's, it appears that this stream may also be part of the
Little Wood hydrologic unit. Genna
Ashley will send this linework and question to Erv Cowley for collaboration.
Study of 1980 or earlier aerial photos may show the natural channels prior to
development activities.
A portion of the Big Wood huc, just above Thorn Creek Reservoir was
redrawn to more accurately reflect the topographical features of the terrain.
Some of the lines were taken from USGS, IDWR, and some were new lines.
Lines
from Nez Perce National Forest: Prior
to the TWG meeting, Al Rea visited with Nick Gerhardt via phone and Tim McDonald
sent some linework to Al. USGS will
take a look at this linework and incorporated any updates/changes where
necessary.
Oregon/Washington
REO data:
The USGS has taken the 4th field boundary lines on the Oregon
and Washington portions of the state in areas where Idaho does not have 24k
linework and incorporated these lines into their project.
If more accurate linework is received by REO in the future, these lines
will be replaced, where applicable.
**Note
– all major changes that were reviewed during this meeting were digitized
using the shapefile “TWG_Meeting_Lines_012505.shp”, and this file will be
sent to Al Rea for reference.
Idaho
Panhandle NF Final Review: Due to
time limitations, this review was tabled until the next watershed meeting on
February 23.
Lower
Snake-Asotin Review: Due to time limitations,
this review was tabled until the next watershed meeting on February 23.
Leigh Bailey took the hard copy of the map, and will coordinate with Katy
Clifton at the Umatilla National Forest for review.
Genna Ashley will send Leigh a shapefile of this huc, which is the
Oregon/Washington REO data to work from.
Middle
Snake-Payette: Due to time limitations,
this review was tabled until the next watershed meeting on February 23.
MISCELLANEOUS
DISCUSSION
Al
Rea stated that USGS has linework for the entire state now.
He would like to send out a second version of this linework –
“Version 1”. This set of
linework would not include any of the changes previously identified, but it
would have the entire state completed, where the previous version was missing
areas. The group decided to send
out another notice asking people to check again and see if their area of
interest has been included, (making sure to note that no prior changes have been
incorporated yet), and provide any additional comments.
The review period for “Version 1” would be approximately 2 weeks.
After any additional comments have been received, reviewed, and
incorporated by USGS, a second “Version 2” would be sent our with all
changes and revisions for a final review. The
review period for “Version 2” would also be approximately 2 weeks.
ACTION
ITEMS:
Genna Ashley will send Al Rea the shapefile that the TWG group
worked with during the review.
Genna Ashley will send Erv Cowley the linework and comments from
Gary Young, USBR so he can review the proposed changes for the Salmon Falls.
Genna will also send Erv the linework she completed for the Big Wood
hydrologic units, along with the question regarding Seaman’s Creek.
Leigh Bailey will work with Katy Clifton in the Umatilla National
Forest on the Lower Snake-Asotin huc and bring the changes back for a review.
Genna Ashley will send Leigh Bailey the shapefile for this huc that was
downloaded from the Oregon/Washington REO site.
Al Rea will continue to work on the 4th field boundaries
and incorporate all pertinent changes into the dataset.
A second “Version 1” will be send to all cooperators asking them to
check any areas that may have been missing from the first set of linework.
