This coverage is built from datasets compiled mainly from the northwest National Forests of USDA Forest Service, Region 5 (Klamath, Shasta-Trinity, Mendocino, Six Rivers, Modoc and Lassen). To fill in missing watersheds in the NWFP area, 1:100,000 scale data was obtained from the Bureau of Land Management. Purpose This data was developed for the USDA Forest Service, Aquatics Riparian Effectiveness Monitoring Program, for use in building a stream layer of the entire NWFP area. Supplemental_Information Procedures_Used 5/20/04 - (cclark, GDM) Reprojected to Albers, NAD 27 to match other NWFP coverages in RSL library. Klamath National Forest - Layer received from Forest with the following attributes: Arc: items KNF_STRM.aat COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME INDEXED? 1 FNODE# 4 5 B - - 5 TNODE# 4 5 B - - 9 LPOLY# 4 5 B - - 13 RPOLY# 4 5 B - - 17 LENGTH 8 18 F 5 - 25 KNF_STRM# 4 5 B - - 29 KNF_STRM-ID 4 5 B - - 33 STRCODE 2 2 C - - 35 SOURCE 20 20 C - - 55 YEAR 4 4 I - - 59 LLID 13 13 C - - Comments in metadata: This coverage contains the streams for the Klamath National Forest that are used to delineate Riparian Reserves. Only stream lines are included; ditches and polygonal features such as wide streams are not included. The intent is to include those streams that meet the Northwest Forest Plan "annual scour" definition. Ground truthing and computer models have been used to extend the "blue line" (quad map) stream lines over most of the area while some areas have had quad map drainageways removed because they are not "annual scour" streams. This coverage is constructed from edited CFF files with additional segments that are wide stream centerlines or connecting lines across lakes or other water bodies or springs. The coverage extends beyond the Klamath Forest boundary to logical watershed breaks. The coverage was created then routed with the LLID routing system, but the route feature class has been dropped. An LLID field is included and populated in the arc attribute table so that the coverage can be re-routed if need be. Most lines are from the 1992 CFF files but many are from a stream densification system used on the KNF. This system uses DEM's, ground truthing, and map interpretation to supplement the original CFF streams. The DEM-based accumulation model was used for the west side of the KNF only, it does not apply to the east side. The DEM streams were used as a guide to help determine where a stream begins, but lines were digitized based on contour maps. Different tolerances (acres of accumulation) were used to best fit the model with ground-truthed information. The Maxwell method (adding streams based on the angle of crenulation) was not used. Arc-level metadata is used to track the source of each arc. In general, areas that have some arcs that are coded as CFF or DEM coded lines have not been ground verified at all. Primarily, roaded areas that have had road inventories (including road/stream crossings) have a great deal of ground truthing, as does the east side of the Forest, while wilderness or roadless areas have little ground truthing. Definitions of Item SOURCE in aat from Klamath metadata: cff - derived from original CFF mapping. Arcs are also attributed as 'cff' if they are the centerlines through wide streams or lakes and connect other 'cff' arcs. 20 acre DEM - stream densification arcs with limits derived from the Digital Elevation Model, 20 acre tolerance, but digitized based 1:24,000 quad map contours 1993 DOQ - streams identified on Digital Ortho Quads GPS - streams mapped with Global Positioning System receivers ground truth - streams identified on the ground but digitized based on 1:24,000 quad maps map interp - other streams digitized based on 1:24,000 quad maps 10 acre DEM -additional stream densification arcs as it appeared 20 acre tolerance did not quite densify enough relative to what could be found on the ground. Processing at the RSL: To identify centerlines and connectors as such in the Klamath National Forest stream layer, a lake coverage needed to be created. The steps are as follows: 1) A reselect was performed from the RSL library CFF line coverage of all arcs constituting waterbodies including double line streams, canals, dam lines, reservoirs. Marshes, swamps were not included. 2) This selection was clipped to NWFP 7.5 minute USGS quad extent. Close dangling arcs; use linework from quad extent to close polygons along clip edge. 3) Additems LCODE and CFFCODE: all lakes coded with CFFCODE = 410, LCODE = 1, all rivers coded with CFFCODE = 403, LCODE = 4 all reservoirs coded with CFFCODE = 413, LCODE = 3 4) Mapjoin rivers, lakes and reservoirs into one layer to create NWCLAKES. 5) To identify islands, reselect from NWCLAKES, lpoly# ne 1 and rpoly# ne 1, build new island layer - select from NWCLAKES (in ArcView) all polys that "have their center in" islands - code with lcode of 2, cffcode of 0. 6) Using Klamath stream layer from forest, KNF_STRM, edit arcs in NWCLAKES to land outside of KNF_STRM centerlines if they intersect. 7) Next, using the ArcInfo command IDENTITY, join NWCLAKES with KNF_STRM to split arcs where they intersect lakes, rivers and streams 8) Add item SPATIALSOURCE Logic for crosswalk from SOURCE to SPATIALSOURCE: -arcs with LCODE ne 0 (which includes centerlines and laterals), code as "CTR" - if Source = "1993 DOQ", Spatialsource = "DOQ" - if Source = "cff", and arc not a centerline/lateral, Spatialsource = "CFF" - if Source = "GPS", and arc not a centerline/lateral, Spatialsource = "GPS" - if Source = "wb connector", Spatialsource = "CTR" - if Source = "ground truth", Spatialsource = "DFT" - if Source = "map interp", Spatialsource = "DFT" - if Source = "20 acre DEM" or "10 acre DEM", Spatialsource = "DEM" If Spatialsource = DEM and CFFCODE = 403, change code CFFCODE to 0 and change Spatialsource to CSC to identify laterals If Spatialsource = DEM and CFFCODE = 410, change code CFFCODE to 0 and change Spatialsource to CSC to identify other centerlines If Spatialsource ne CTR, CRU or CSC and STRCODE = P, code CFFCODE = 402(stream, perennial) If Spatialsource ne CTR, CRU or CSC and STRCODE = I, code CFFCODE = 405(stream, intermittent) On all other arcs where Spatialsource = CTR or CRU, code CFFCODE = 0 9) Drop items SOURCE, YEAR and LLID *********************************************************** Lassen National Forest - Routed coverage received from Forest with the following items: Arc: items LNFSTREAM.aat COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME INDEXED? 1 FNODE# 4 5 B - - 5 TNODE# 4 5 B - - 9 LPOLY# 4 5 B - - 13 RPOLY# 4 5 B - - 17 LENGTH 8 18 F 5 - 25 LNFSTREAM# 4 5 B - - 29 LNFSTREAM-ID 4 5 B - - 33 CFF-CODE1 10 10 I - - 43 CFF-CODE2 10 10 I - - 53 CFF-CODE3 10 10 I - - 63 CFF-CODE4 10 10 I - - 73 CFF-CODE5 10 10 I - - 83 DATE 8 8 D - - 91 FEET 4 12 F 3 - 95 STREAMORDER 2 2 I - - 97 STREAMTYPE 3 3 C - - 100 SOURCE 10 10 C - - 110 SPANNER 4 4 I - - 114 FLANKER 4 4 I - - 118 MILES 8 8 F 2 - 126 STRCODE 1 1 C - - 127 CORRTYPE 1 1 C - - 128 SOURCECODE 2 2 I - - 130 MEMO 80 80 C - - 210 NEWCFF1 10 10 I - - 220 LLID 13 13 N 0 - Arc: items LNFSTREAM.RATSTREAMS COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME INDEXED? 1 STREAMS# 4 5 B - - 5 STREAMS-ID 4 5 B - - 9 LLID 13 13 N 0 - 22 SYMBOL 1 1 I - - Lassen National Forest processing at the RSL: 1) Edgematch to Modoc National Forest by erasing Lassen layer with Modoc quad extent 2) Lassen layer clipped with Huc6 watersheds to just outside NWFP boundary.

This coverage was found to contain many incidences of coincident arcs. Examples of this include: - an arc that appears to originate from a cff coverage alongside another arc that appears to represent the same stream but looks very crudely digitized, often each have different stream codes (item 'strcode') - in some cases, triple coincident arcs were present - a few cases of two arcs that were exactly coincident existed In most cases, the arc that originated from the cff coverage was retained. Otherwise, the arc that appeared to be more accurate according to available ortho-quads was used. 2) Clip Modoc layer with Huc6 watersheds to just outside NWFP boundary. 3) Item SPATIALSOURCE added and coded as follows: Source of "1" - Spatialsource = "CFF" (some of these were coded as ephemerals that in CFF's were intermittent) Source of "0" and no cffcode - Spatialsource left null 4) Added item "SOURC_AGEN" and coded MDF.

This layer was developed by the Watershed Assessment Program, a cooperative effort by the USDA Forest Service and California Department of Forestry. The procedures in it's development were based on BLM's Oregon/Washington Hydrography Handbook using the LLID routing approach. The base linework is from 1:24,000 Forest Service Cartographic Feature Files (CFFs) and 1:24,000 USGS DLG-3 files.

Processing of ALLSTRMS8 at the RSL: 1) Using a selection of Huc6 watersheds, portions of ALLSTRMS8 and the Klamath, Mendocino Forests were erased for edgematching. The following items were saved from the ALLSTRMS8 layer: Arc: items ALLSTRMS8.aat COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME INDEXED? 1 FNODE# 4 5 B - - 5 TNODE# 4 5 B - - 9 LPOLY# 4 5 B - - 13 RPOLY# 4 5 B - - 17 LENGTH 8 18 F 5 - 25 ALLSTRMS8# 4 5 B - - 29 ALLSTRMS8-ID 4 5 B - - 33 MINOR1 6 6 I - - 39 MINOR2 6 6 I - - 45 MINOR3 6 6 I - - 51 SPATIALSOURCE 3 3 C - - 54 STRM_TYPE 12 12 C - - 66 DATA_SOURCE 20 20 C - - 86 JOIN_ID 4 5 B - - 3) Added item CFFCODE, STRCODE, SOURC_AGEN.

Therefore, it was decided at the RSL to use only the ephemerals from this layer and the balance of the Forest perennial and intermittent streams would be contained in the ALLSTRMS8 layer (as described above). Six Rivers processing at the RSL: 1) Pull ephemerals from SRF_STREAM as follows: Join the SRF_STREAM.ARCDATA info file to SRF_STREAM.AAT using join-id. This joins in the item SPATIALSOURCE. Based on the following table from the Six Rivers SRF_STREAM layer metadata, arcs coded with "CRS" and "CRU" were selected and retained as a separate coverage. SPATIALSOURCE: CFF - Cartographic Feature Files Forest Service CRU - Derived from 24k contours, Maxwell, et al. crenulation CRS - Derived from 24K contours, SRNF crenulation CSC - Artificial Secondary Path (secondary channel or connector arc) CTR - Artificial Primary Path (primary channel centerlines) DIS - Arcs generated to connect a discontinuous channel DLG - USGS Digital Line Graphics Files 2) Add SOURC_AGEN and code as SRF. Drop all unneeded items. *********************************************************** Mendocino National Forest - No metadata attached. An email from Andy Taylor, GIS Coordinator, Mendocino National Forest: The original source of the arcs was the CFF's (1980's version). The entire Forest was crenulated for the LMP effort about 1980. These lines were drafted on mylar and added to the CFF's. This process was done by HUC 5 as part of the watershed assessment efforts. The rest of the Forest not covered by a WA was completed around 2000. As you can see some HUC5 were done more intensively than others. It was then determined at a province meeting that we had been a little overzealous in crenulating streams and some of them did not meet the definition of a stream in the NWFP ROD. We contracted with Titan to identify those arcs that did not meet the definition from the ROD and give them a different spatialsource. In 2003 we replaced the 1980's CFF's with the 1996 CFF's. The contractor only worked on streams that were all or partly within the Forest boundary. They apparently labeled everything as meeting the definition and then identified the arcs that didn't. I eliminated the arcs that didn't meet the definition in the cover I sent you. The method Titan used at least partially explains why the density is higher outside the Forest than inside in some areas(i.e. The NE corner). The codes for Spatialsource and wtrbodytype come from the Oregon/Washington BLM Hydrography handbook last update 8/24/1999.

Coord_source, hyd_feature_id, and course_cl are user defined items. Coord_source provides information on the source of vertices and arcs in the data. In this case, all coordinate source is USGS 100k DLG data. Hyd_feature_id is an internal ID number used to tie arcs that make up a river to the name of the river - stored in Info and an Informix table. Course_cl indicates if the arc is a stream center line created in areas of lakes, resevoirs, and double bank streams.
