 HUC REVIEW

Lake Walcott 17040209 – There are several 4^th field boundary differences between Lake Walcott and surrounding hydrologic units.  The TWG group worked on one 4^th field boundary area between the Lake Walcott and Upper Snake Rock units (see shapefile TWG20050923.shp for specific line placement).  There is another area between the Lake Walcott and Raft River hucs, at the mouth of Raft River.  Valdon Hancock is working on this huc and will have it completed soon.  When Valdon’s edits are complete, we will edge-match Lake Walcott with his work in that area.  The other 4^th field boundary difference is located between the Lake Walcott and Big Lost hydrologic units.  Genna Ashley will pull the old delineations for the Big Lost unit, before this area became part of the Lake Walcott unit, and merge the 5^th and 6^th field linework into the Lake Walcott huc, renumber, etc.  These changes will be incorporated and sent to Erv Cowley at the BLM for his review.  This huc will be put on the October agenda for a continuing review. 

Palisades 17040104 – Genna Ashley reviewed the changes she had made resulting from the 7/22/05 TWG meeting.  Idaho incorporated the Wyoming linework and attributes where available.  Idaho split the Palisades Reservoir (Lower Palisades Reservoir 6^th) area differently from Wyoming’s delineations.  The reasons for the Idaho split are as follows:  1) The Little Elk Creek area is too small for a 6^th field (8100 acres), 2) The group did not want to break up the pure 6^th field Lower Big Elk Creek, and 3) the logical break for Lower Palisades Reservoir is at the dam.  Genna Ashley will make these changes and send this and all other Idaho/Wyoming hucs to Caribou-Targhee National Forest, and Wyoming cooperators.  This huc is considered draft-approved for concept lines.  The 24k linework will need to be checked and possibly updated in the future.

Medicine Lodge 17040215 – This huc was reviewed by the group.  The changes that were identified from the previous review were gone over and approved.  There were several 6^th field numbering changes that needed to be made.  A portion of the 5^th field huc “Idaho National Engineering Laboratory” was re-sectioned and will be included with a portion of the Bare Canyon (will be renamed to “Mud Lake) 5^th field unit.  See shapefile TWG20050923.shp for specific line placement.  The “Idaho National Engineering Laboratory” 5^th field name will shorten to “Idaho National Laboratory”.  When these changes have been made, this huc will be sent to the INL contact people (Luke White) for review.  This huc will also be sent to Christa Braun and Erv Cowley, BLM for their suggestions.  Information per Christa – Nina is refining the 24k linework for the Medicine Lodge unit.

American Falls 17040206 –                 This huc was not reviewed by the group.  It will be put on the October agenda for a continuing review. 

Birch Creek 17040216 - This huc was reviewed by the TWG.  The 6^th field area previously named “Birch Creek Valley” was redrawn and named “Birch Creek Headwaters”.  Several other 6^th fields in that area were renamed and renumbered.  The Irish Canyon and Scott Canyon 6^th fields were too small, and therefore combined into the composite and renamed “Birch Creek-Irish Canyon”.  Many 6^th field hucs were renamed and/or renumbered.  For specific line placement, see shapefile “TWG20050923.shp.  Christa Braun and Nina Madry (BLM) are working on 24k line refinement for Birch Creek.  Christa Braun will send Genna Ashley the latest BLM linework, and Genna will incorporate the above-mentioned changes into the BLM linework.  As soon as these linework and attribute changes are incorporated, this huc will be brought back for a final review.

Beaver Camas 17040214 – This huc was not reviewed by the TWG.  The changes from the prior review were sent to BLM and they are in the process of reviewing the changes.  This huc will be put on the October agenda and reviewed at that time.

Blackfoot 17040207 – The TWG group looked at this huc and made some very preliminary recommendations and observations.  IDWR will delineate the 5^th and 6^th field units for this huc and bring it back for a continuing review.

Portneuf  17040208 - The TWG group looked at this huc and made some very preliminary recommendations and observations.  IDWR will delineate the 5^th and 6^th field units for this huc and bring it back for a continuing review.

ACTION ITEMS:

Genna Ashley will make the changes on the above-mentioned items and coordinate with each cooperator for reviews.

Linda Davis will look for bathymetry for the American Falls hydrologic unit, and check the reservoir area.

MISCELLANEOUS DISCUSSION

BLM is currently working on the 24k linework refinement for Birch, Beaver Camas, and Medicine Lodge hucs.  Genna Ashley will coordinate with Christa Braun to make sure all the current linework is merged with the current attributes and recent changes made by the TWG.

There is a missing line between the 4^th field boundary of the Upper Snake-Rock and Little Wood hydrologic units.  Genna Ashley will restore this line and send a shapefile or coverage to USGS for incorporation into their dataset.
