Al
Rea stated that the DOI money has been substantially cut back and Idaho is
unsure of how much funding they will receive to complete work on the State NED
1/3” data.
Gene Dana spoke of the NHD progress for the following
hucs:
In support of the NHD in Idaho,
we in the Boise Idaho State Liaison office, have identified 13 Hydrologic Units
(HUCs) that need to be finished. When
completed these 13 HUCs/Sub-basins would provide complete coverage over the
State of Idaho, and would be a layer to The National Map to be archived at Univ.
of Idaho. The Forest Service
representative in Corvallis, OR has identified an additional 2 HUCs in the Hells
Canyon area that were previously thought to have been allocated to RMMC in
Denver. (See the Hi-Resolution NHD
Status Map of 10/31/03), they are listed and colored as “planned for future
work.” (see below). Another HUC
17060305 is undetermined as of Nov 2003. This brings the total number of HUCs to
16. By Mar 2004, 3 HUCs
completed, 3 under contract, 1 in NHDArc status, 9 HUCs left.
17010216, 17010308, 17010307
The Rathdrum Prairie Project lacks these 3 HUCs. This is part of a “Spokane Valley – Rathdrum Prairie Hydrologic Study – Proposed Project Scope” by Idaho Dept. of Water Resources, Washington Dept. of Ecology, and the USGS, Water Resources Dept., July 2003. We have DLGs. CFF data for two 24k quads from the Colville Natl. Forest were downloaded 27 Oct 2003. On 22 Oct, FS clearance was granted. All quads are available.
17010307 – Lower Spokane, WA,
It is a Natl Park Service priority
#162 (Lake Roosevelt Natl Rec Area) see 21 Oct 2003 status map, NHD to do. 17010308,
Little Spokane is in NHDinArc status as of Mar 2004.
17060103 This HUC is on
the border of Idaho, Washington & Oregon. There are Wallowa-Whitman NF lands
& Umatilla NF lands; we are seeking 12 CFF quads. Lower Snake-Asotin,
is a Natl Park Service priority
#188 (Nez Perce Hist Park) see 21 Oct 2003 status map. Mar 2004, waiting for
delivery of Forest data.
17050201, 17060101 These 2 HUCs are on the OR/ID border in the Hells
Canyon area. They were previously
thought to have been allocated to RMMC in Denver (Part of an original 51 HUC
contract to RMMC from the Oregon forests). Region 6, NF data manager is
providing NW Hydro Framework data in late OCT for these 2 HUCs, and as of 28
Oct, FS is contracting these two out.
Jan 2004, notified that contractor has both of them.
17050102, 17050103, 17050104, 17050105, 17050106, 17050107, 17050108
These 7 HUCs are located in SW Idaho in Owyhee County and all have a
border with either OR and/or NV. All
of these HUCs have BLM lands on them. The
Nevada portion of these HUCs (4) need 24k quad TVH creation (41) as there are no
existing Hydro coverages.
17050102 & 17050104 have Humboldt NF lands.
17050106 also has forest lands
and we have talked to the Forest Service representative about obtaining data.
17050102 is part of the 7
Subbasins that the Forest Service is completing in FY2004 for the
Humbolt-Toiyabe NF. Jan 2004, contractor has it.
17050115
This HUC is located near Payette, ID, and is a priority to the Idaho
Dept. of Water Resources. It has been identified as a learning priority to the
Idaho State Liaison office. All DLG quads are available. Sent to MCMC for NHDArc creation in Feb
2004, which was completed in March 2004.
16020309
This HUC is in the Curlew Valley, bordering Utah.
Utah has committed funding to collect this one and is asking for
additional funds (@ 4K) from Idaho to do that portion as well. At this point,
Nov 2003, we lack 1K. It is a Natl Park
Service priority #145 (Golden Spike Natl Hist Site) see 21 Oct 2003 status
map NHD started 30 Aug 2003. Notified Jan 2004 of its completion.
17060305 This HUC was previously coded as distributable but now is uncoded. Status call of 6 November 2003 stated that the discrepancy would be researched. S Fork Clearwater, It is a Natl Park Service priority #188 (Nez Perce Natl Hist Park) see 21 Oct 2003 status map,
NHD done 16 Oct 2002. Dec 2003,
completion confirmed by call.
All of these HUCs have support
and interest from various agencies including the Boise Idaho State USGS Liaison
office. The Idaho State Dept. of Water Resources, BLM Idaho State Office, Idaho
Dept. of Water Quality, US Bureau of Reclamation, and Idaho Dept. of
Fish & Game, USGS Water Resources Division, and various irrigation
companies have all expressed interest in acquiring this HUC data.
In summary, 8 HUCs/Sub-basins are
projected being complete in the near future FY2004. It is hoped that funding and
work for all of the remaining HUCs will be secured.
Idaho NHD Report by Gene Dana
Idaho State USGS Liaison office
Boise, ID
Al
Rea talked about the project USGS is involved with in cooperation with DEQ.
This project is an extension of the StreamStats project, and will be
classifying low-flow streams as either perennial or intermittent, using
regression equations and the 7Q2 – 7Q10.
The purpose of this study is to create low flow statistics and to
determine intermittent streams based on DEQ’s definitions which is less than
.1 cfs for 7Q2, using an interactive algorithm that will test the headwaters and
the lower end, and if finding greater than .1 cfs for upper end, but not the
lower end, the points will be tested along the stream to find where the stream
becomes intermittent.
In
order to complete this study, the hydro will be “burned in” with the 10meter
1/3” DEM data. They will need to
have 24k NHD data for the entire state and this data will be processed by
8-digit hucs, so the 8-digit huc boundaries will need to be completed to match
the 24k ridgelines. Steve Garcia
with the USGS may have some time to work on these boundaries. This project will concentrate on natural flow only; the
canals and ditches will be ignored. Al
Rea asked if there were any 4th field boundaries that had been
completed. Linda Davis stated that
the Panhandle National Forest had done some very good work with their
boundaries. Genna Ashley stated
that some work had been done on the Lower Boise 4th field boundary,
and she would look into other hucs that had boundaries that were either complete
or close to complete for 24k linework. Al
Rea stated that they would be working on 17050111, 17050112, 17050113 and
17050114 for the pilot project.
Palouse
17060108
– The group reviewed this huc. It
was decided to break the 5th field Upper Palouse River at Deep Creek.
The Palouse River-Gnat Creek 6th field outlet should be moved
to the confluence. The name Palouse
River-Mile 114 was changed to Palouse River-Dry Creek.
Palouse River-Brush Creek name should be changed to Palouse River-Dry
Creek. The group could not
immediately find a hydro name for Palouse River-Colfax (the town).
It was suggested that the name Colfax should be changed to reflect any
named hydro in the area. IDWR will
check all available sources and try to find a named feature within this huc,
possibly contact Oregon/Washington for a name, and get back to Dick Jones with
something. Dufield Creek should be
Palouse River-Dufield Creek. The 6th
field confluences within the Union Flat Creek 5th should be snapped
to each confluence. Also, we need
to check with the OR/WA folks and see if they have any named hydro for these 6th
fields. The outlet that meets the
Snake River needs to be cleaned up. Genna
Ashley will make the changes on the Idaho side and send this linework to OR/WA
and let them know of the Idaho changes and any additional suggested
changes on the Washington side to the OR/WA data stewards.
Genna Ashley will send Dick Jones and Sue White the graphic file we
worked on during the meeting with suggested changes.
Payette
17050122
– The group reviewed this huc. The
large 5th field huc at the southern portion of the watershed was
looked at in detail. It was
determined that Black Creek can’t be delineated, and a justification should be
written to keep this 6th field large.
There was a change to re-delineate another 6th within this
watershed to the confluence of Big Willow Creek.
The Upper Squaw Creek 6th will be grouped with the Lower Squaw
Creek 6th and become part of the Upper Squaw Creek 5th
field huc. Genna Ashley will make
these changes and send a copy to T.J. Clifford at the Boise National Forest.
This huc should be ready for a final review during the next TWG meeting in
March.
Salmon
Falls 17040213
– The group reviewed this huc. The
Devil Creek 5th will become a pure huc.
Leigh Bailey and Erv Cowley worked to name and number the 5th
and 6th fields within this watershed.
Erv Cowley will work on the changes identified for this huc and bring it
back for a continuing review, probably in April for the National TWG meeting.
Big
Wood 17040219
– There will be some naming and numbering changes for this huc, and there was
some discussion about the southern area of this huc.
It was decided to bring this huc to the April meeting with the national
folks to get some input and direction. This
huc will be again reviewed in April, during the national meeting.
Palisades
17040104
– Some of the composite names will be hyphenated.
Sandra is finishing up the 1:24k work, snapping the linework to the
confluences of the NHD. After the
name and numbering changes, and 24k linework is completed, this huc will be
considered draft-approved.
Central
Bear 16010102
– Linda Davis went over the draft 5th and 6th field
delineations for this huc. Utah has
already delineated the southern portion of this huc, and Idaho will keep that
linework. The group liked the draft
5th and 6th field concept lines Linda has proposed, and
she will work on these and bring this huc back for a continuing review.
Yaak
and Upper Kootenai (Montana)
– The group reviewed the Montana linework for this huc.
After a review of the linework, the Idaho TWG did not see any reason to
change any of the delineations Montana has proposed, and Idaho will consider the
Yaak and Upper Kootenai huc draft approved.
The
proposed format of the April meeting with the National Watershed Team was
discussed. It was decided to have
the meeting in two days, with the first day being the Technical Working Group
meeting so that the National people can get a general idea about how the Idaho
process works, and give the Idaho people an opportunity to bring their most
difficult hucs for expert assistance. The
second day would be geared toward the National effort, with an emphasis on Idaho
processes and procedures. The
tentative date for this is Thursday and Friday, April 22-23.
Al Rea will check the availability of the USGS conference room facility
that can hold 50-75 people.
It
was decided to schedule the Teton, Salmon Falls, and Big Wood River hucs for the
April review, because these hucs each have very unique and difficult areas to
delineate, and pose interesting issues and questions.
ACTION
ITEMS:
Linda
Davis will call Cindy Clark regarding the status of the Curlew Valley 24k NHD
data, and find out when it will be officially available.
Genna
Ashley will check and see which hucs have boundaries that are 24k or close to
24k that can be used for Al Rea’s stream project.
IDWR
will check all available sources and try to find a named feature for the Palouse
River Colfax 6th field huc, and possibly contact Oregon/Washington
for a name, and get back to Dick Jones with something.
IDWR
will check with the OR/WA folks and see if they have any named hydro for the 6th
field hucs within the Union Flat Creek area.
Genna
Ashley will make the changes on the Idaho side of the Palouse huc, and send this
linework to OR/WA and let them know of the Idaho changes and any additional suggested
changes on the Washington side to the OR/WA data stewards.
Genna will also send Dick Jones and Sue White the graphic file we worked
on during the meeting with suggested changes.
Genna
Ashley will make the changes on the Payette huc and send a copy to T.J. Clifford
at the Boise National Forest. This huc should be ready for a final review during
the next TWG meeting in March.
Erv
Cowley will work on the changes identified for the Salmon Falls huc and bring it
back for a continuing review, probably in April for the National TWG meeting.
Erv
Cowley will continue to work on the Big Wood huc and bring it to the April
meeting to get input and direction from the national folks.
Linda
Davis will continue to refine the concept work that she has done on the Central
Bear huc and bring it back for a continuing review.
Al
Rea will check the availability of the USGS conference room facility that can
hold 50-75 people for the April 22-23 Idaho National Watershed Meeting.
