HUC REVIEW

Lake Walcott 17040209 – The TWG reviewed this huc.  The new 5^th field delineation (Champagne Creek) at the northern portion of the huc, will be split into two 6^th field hucs, in order to separate out Champagne Creek as a 6^th field.

All of the Rattlesnake Butte and Larkspur Park 5^th field units will be “zero’d out” for the 6^th fields because of lava and no hydrologic features to delineate.

The Paddleford Flat and East Paddleford Flat 6^th field units will be combined within the Wagon Butte 5^th field unit.

The Mac Rae Lake and Spud Butte 6^th field units will be combined within the Wagon Butte 5^th field unit.

The Broken Top Butte, Sand Butte, Rock Lake, Black Ridge Well, Black Ridge Crater, Shale Butte, and Monument Reservoir 6^th field units will be combined into one oversized 6^th field unit within the Black Ridge Crater 5^th field, due to no hydrologic features to delineate.

The Brockie Lake, Crystal Ice Cave, and Whiskey Butte 6^th fields will be combined into one 6^th field within the Minidoka 5^th field unit.

The Brigham Point and Wapi 6^th field units will be combined into one 6^th field within the Snake River-Lake Walcott 5^th field unit.

Part of the eastern portion of the Lake Channel Canyon 6^th field unit will be redrawn and put with the Snake River-Little Creek 6^th field unit.  This will change the 5^th field designation for this area, to the Snake River-Massacre Rocks 5^th.

The 5^th field division between Snake River-Massacre Rocks and Snake River-Lake Walcott units will be redrawn to break at a small stream confluence.

A portion of the 6^th field boundary line between the Snake River-Parees Island and Snake River-Jackson may be redrawn and moved south (see shapefile TWG20051117.shp for exact line).  Erv Cowley and Christa Braun will make this determination.

A portion of the 5^th field line between the Rupert and Snake River-Milner Dam 5^th field units will be redrawn.  Also, the 6^th field line between the Snake River-Burley and Snake River-Starphs Ferry units will be redrawn.  See shapefile “TWG20051117.shp” for line placement in this area.

For all above-mentioned changes, refer to shapefile created during the meeting, “TWG20051117.shp”.  Genna Ashley will send Erv Cowley and Christa Braun the Lake Walcott shapefile and also the TWG20051117 shapefile, and they will make the changes to this huc.

Birch Creek 17040216 – The TWG reviewed this huc.  There was one small change in the 6^th field linework for the Birch Creek Headwaters 6^th field unit.  This line was redrawn (see shapefile TWG20051117.shp).  Genna Ashley will make this small change, and this huc will be considered draft approved.

Medicine Lodge 17040215 – The TWG reviewed this huc.  The confluence at the 6^th field huc Webber Creek was cleaned up.

The Medicine Lodge Creek 6^th field unit was redrawn to create a pure 6^th, and the leftover portion of the huc was put into the Medicine Lodge Creek Outlet 6^th field.

The 6^th field unit 170402150302 (no named 6^th field feature available) was combined with the Deep Creek Outlet 6^th field unit.

The 6^th field boundary line between the Johnston Lake, North Lake, and Mud Lake was redrawn – see shapefile TWG20051117.shp for details.

A portion of the 5^th (and 6^th ) field boundary between the Mud Lake and Idaho National Laboratory 5^th field units will be redrawn (see shapefile TWG20051117.shp).

The 170402150604 and 170402150603 (no named 6^th field features) 6^th field units will be combined into one 6^th field unit, within the Idaho National Laboratory 5^th field unit.

The Argonne West and 170402150602 (no named 6^th field features) 6^th field units will be combined into one 6^th field unit, within the Idaho National Laboratory 5^th field unit.

The Taylor Well, 170402150607, and 170402150609 (no named features available on the numbered hucs), will be combined into one 6^th field unit, within the Idaho National Laboratory 5^th field unit.

Name changes:  huc 170402150508 will be renamed Second Owsley Canal.  Huc number 170402150610 (Second Owsley Canal) will be renamed Crystal Lake Canal.

There is one very large proposed 4^th field boundary change between the Medicine Lodge and Beaver Camas hydrologic units.  This will be discussed during the December, 2005 TWG meeting.

For all above-mentioned changes, please see shapefile “TWG20051117.shp”.  Genna Ashley will make these changes, and send the final linework to Luke White, Randy Lee and/or Julie Bisbee at INL for possible review.  After the linework changes have been made, this huc will be considered draft approved, pending the possible 4^th field boundary change, or any changes INL may propose. 

Beaver-Camas 17040214 – The TWG reviewed this huc.  Erv Cowley stated that Camas Creek feeds into Mud Lake, and therefore, the Mud Lake Area (currently in the Medicine Lodge 4^th field unit) should be moved into the Beaver-Camas huc.  This would be hydrologically correct.  If this change were implemented, it would take the Holly Canal, Mud Lake, North Lake, and 170402150508 (no named 6^th field features) 6^th field units within the Mud Lake 5^th field unit and move them into the Beaver Camas 4^th field huc.  These 5^th and 6^th field features would then become part of the Camas Creek Outlet 5^th field unit within the Beaver-Camas huc.  This issue will be revisited during the December TWG meeting.

ACTION ITEMS:

Christa Braun will make the changes for the Lake Walcott hydrologic unit, after she receives the meeting notes and TWG linework from Genna Ashley.

Genna Ashley will make the changes for the Birch Creek, Medicine Lodge and Beaver Camas hucs.

The TWG will make Upper Snake-Rock and the Blue Gill landslide area in Salmon Falls a priority, putting them on the December agenda.

Genna Ashley will send Valdon Hancock the latest Upper Snake Rock linework – this huc will be put on the December agenda.

MISCELLANEOUS DISCUSSION

Erv Cowley would like to move a boundary in the Salmon Falls hydrologic unit.  This are is a shared area with Utah.  The area in question is the Blue Gill landslide, that is still moving.  Erv has moved this line to the dam; the original delineation was to the stream, but it is hydrologically correct to move it to the landslide area.

The TWG will make Upper Snake-Rock and the Blue Gill landslide area in Salmon Falls a priority, putting them on the December agenda.  Valdon Hancock and Erv Cowley are retiring January 3rd, and the group would like to get their input before they leave.  Genna Ashley will get the latest Upper Snake Rock linework from Sandra Thiel and send it to Valdon Hancock so that he may begin his review.

Erv Cowley has received the latest linework from Nevada for the Owyhee units along the border.  Nevada has only delineated these hucs to the 5^th field.  Erv Cowley will propose funding service to the BLM to complete the Idaho portion of the Owyhee hydrologic units.

NEXT SCHEDULED TWG MEETING (S):

Tuesday, December 13^th, at the Idaho Department of Water Resources in Boise, ID.  The meeting will begin at 9:00 a.m.
