This portion of the data release presents topographic data collected at 5 study sites along Elwha River, Washington between 2006 and 2017. Elevations along channel-perpendicular transects were surveyed using a total station and prism rod. Initial geodetic control was established using static global positioning system (GPS) occupations. A total station was subsequently used to expand and maintain the survey control network at each site. All survey data were referenced to the NAD83 datum, using the UTM, zone 10, coordinate reference system. All elevations were referenced to the NAVD88 vertical datum. Based on repeat measurements of points with known positions, we estimated the horizontal and vertical accuracy of the topographic measurements to be within 2 to 3 cm. Topographic data were collected using a total station using survey layout routines to locate data along the same transects during each survey. Wetted portions of the channel were measured primarily by wading with the survey rod. In several locations where wading was not feasible due to water depth, measurements were not taken or they were made by swimming with the survey rod or by deploying the survey rod from an inflatable kayak (necessary in the thalweg of reach 3 between 2006 and 2011). Although the focus of the surveys was to make repeated measurements of elevations along a transect, some additional topographic measurements were within the reaches off of the transects. Additionally, a small side channel within reach 2 was surveyed from 2006 to 2008 along transects perpendicular to that channel and along the channel's thalweg. Two series of figures are provided to aid with visualizing the channel cross-section data. The first series, labeled “Elwha_CrossSectionPlots_FallSurveys_*.png”, shows the channel cross-section profiles from the annual fall surveys, plotted for each transect and each reach. The second series, labeled “Elwha_CrossSectionPlots_Grid_FallSurveys_*.png”, shows the channel cross-section profiles from the annual fall surveys for each reach, with each survey date and transect on a separate set of axes to provide a better means of viewing cross-section changes between survey dates (note that Reach 1B was not plotted this way because it was surveyed less frequently).
Data were collected to study sediment in the Elwha River before and after the removal of the Glines Canyon and Elwha dams at four reaches along the Elwha River, with five or six transects at each reach.

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Initial survey control for all topographic transects was established using static GPS occupations, which have an estimated horizontal accuracy of around 1.5 cm. Subsequent survey control densification within each reach was conducted using a total station. Repeat check measurements conducted during the surveys on points with established coordinates suggest a horizontal precision of around 3 cm for measurements at these sites.
Initial survey control for all topographic transects was established using static GPS occupations, which have an estimated vertical accuracy of around 2.5 cm. Subsequent survey control densification within each reach was conducted using a total station. Repeat check measurements conducted during the surveys on points with established coordinates suggest a vertical precision of around 3 cm for measurements at these sites.
Riverbed elevations along channel-perpendicular transects were measured in five sites. Initial geodetic control was established using static global positioning system (GPS) occupations within the study reaches in locations with a clear, unobstructed view of the sky. A total station was subsequently used to densify and maintain the survey control network within each reach. Horizontal and vertical accuracy are estimated to be within 2 to 3 cm. Wetted portions of the channel were measured by wading, swimming, or by inflatable kayak, and deploying the survey rod.

TRANSECT
An alpha-numeric code identifying the reach and transect of the collection, formatted as "reach-transect." For example, "R2-T3" represents Reach 2, Transect 3.
U.S. Geological Survey
See "REACH" attribute for “reach-” identifying codes. For the “transect” portion of the alpha-numeric code, the following definitions are used: T0=Transect 0; T1=Transect 1; T2=Transect 2; T3=Transect 3; T3B=Transect 3B; T4=Transect 4; T5=Transect 5; T6=Transect 6; SC5-T1=Side channel 5, transect 1; SC5-T2=Side channel 5, transect 2; SC5-T2B=Side channel 5, transect 2B; SC5-T3=Side channel 5, transect 3; SC5-T4=Side channel 5, transect 4; SC5-T5=Side channel 5, transect 5; SC5-T6=Side channel 5, transect 6; SC5-T7=Side channel 5, transect 7; ; SC5-T8=Side channel 5, transect 8; SC5-THAL=Thalweg of side channel 5; TOPO=elevation points collected off transect. Note that transects associated with side channel 5 (SC5; not shown on index map) are separately numbered transects than the transects in the rest of Reach 2. Additionally, SC5-T2B is located between transects SC5 transects 2 and 3.
PID
Unique identifier for the survey point collection ID. Unique for survey date at reach, but not unique between reaches, or between dates. (PID value may be repeated in the same file on separate dates).

CODE
Data collection identifier.
U.S. Geological Survey
Alpha-numeric code, in TRANSECT-XX format, used to identify topographic measurements points that have additional samples collected for grain-size analysis. See TRANSECT attribute for the description of the first part of the code. The addition of suffix "-CC" indicates a CobbleCam image was collected at that location, and the addition of code “-SL” indicates that a sediment sample was collected at that location and analyzed back in the sediment lab. No suffix means that a grain-size sample was not collected at that location.
