High-resolution orthophotograph of Fall Creek Lake, Oregon, acquired during annual drawdown to streambed November 10, 2016

The Middle Fork Willamette River basin encompasses 3,548 square kilometers of western Oregon and drains to the mainstem Willamette River. Fall Creek basin encompasses 653 square kilometers and drains to the Middle Fork Willamette River. In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey evaluated geomorphic responses of downstream river corridors to annual drawdowns to streambed at Fall Creek Lake. This study of geomorphic change is focused on the major alluvial channel segments downstream of the U.S. Army Corps of Engineers’ dams on Fall Creek and the Middle Fork Willamette River, as well as the 736 hectare Fall Creek Lake. Reservoir erosion during streambed drawdown results in sediment delivery to downstream reaches. To better understand patterns and processes of reservoir erosion related to downstream geomorphic responses, detailed reservoir deposit mapping and change analyses are completed.
To support these analyses, aerial photographs were collected via unmanned aerial systems (UAS) on November 8 and November 9, 2016, and via Cessna aircraft (or manned aerial system; MAS) on November 10, 2016, to create 3-dimensional xyz point clouds, digital elevation models (DEMs), and orthophotographs of the Fall Creek Lake bottom during full reservoir drawdown using structure-from-motion (SfM) techniques. The November 8 model resulted in a ground resolution of 3.28 centimeters per pixel, average point density of 58.2 points per square meter, and DEM resolution of 13.1 centimeters per cell. The November 9 model resulted in a ground resolution on 2.86 centimeters per pixel, average point density of 76.6 points per square meter, and DEM resolution of 11.4 centimeters per cell. The model for the manned aerial system (MAS) flight on November 10 had a slightly lower ground resolution at 4.18 centimeters per pixel (for multiple altitudes), average point density of 35.8 points per square meter, and output DEM resolution of 16.7 centimeters per cell. Cell sizes were automatically generated by the software.
This documentation describes the high-resolution orthophotograph of Fall Creek Lake, Oregon, created from aerial photographs acquired when lake levels at streambed on November 10, 2016. This dataset is part of a broader publication including aerial photographs, 3-dimensional xyz point clouds, DEMs, orthophotographs, model processing reports, ground control points, and dataset footprints for November 8-10, 2016.

Debris Flow Video Files for Wide Angle Camera (Station 1), Chalk Cliffs, Colorado, USA, 2016

Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). This "Child item" page includes videos of debris flows captured by one of the high-definition cameras at the monitoring site in Chalk Cliffs, CO. This camera (Wide-angle camera) is located near Station 1 on the opposite side of the basin with a broad view of the channel. The attached figure "station_and_camera_locations.png" provides an overview figure with the location of the three cameras and three stations along the channel. 
Video recording for all cameras is triggered using a rainfall threshold, derived from rainfall measurements from a rain gauge (Michel et al., 2019). The complete videos for all the cameras are downloaded manually during site visits. More detailed information about the cameras and settings used can be found in the metadata file under “Process steps” in “Data quality information.”  
During 2016, several debris flows were captured by the 'Wide-angle Camera'. The videos for all debris flows captured by this camera along with the dates they were captured can be found in the attached zip folders. The file names indicate "date_camera_debrisflow."

Night Heron Time Budget Data

Parental incubation behavior largely influences nest survival, a critical demographic process in avian population dynamics, and behaviors vary across species with different life history breeding strategies. Although research has identified nest survival advantages of mixing colonies, behavioral mechanisms that might explain these effects is largely lacking. We examined parental incubation behavior using video-monitoring techniques on Alcatraz Island, California, of black-crowned night-heron Nycticorax nycticorax (hereinafter, night-heron) in a mixed-species colony with California gulls Larus californicus and western gulls L. occidentalis. We first quantified general nesting behaviors, incubation constancy, and nest attendance, and a suite of specific nesting behaviors (i.e. inactivity, vigilance, preening, and nest maintenance) with respect to six different daily time periods. We employed linear mixed effects models to investigate environmental and temporal factors as sources of variation in incubation constancy and nest attendance using 211 nest days across three nesting seasons (2010–2012). We found incubation constancy (percent of time on the eggs) and nest attendance (percent of time at the nest) were lower for nests that were located &lt; 3 m from one or more gull nest, which indirectly supports the predator protection hypothesis, whereby heterospecifics provide protection allowing more time for foraging and other self-maintenance activities. To our knowledge, this is the first empirical evidence of the influence of one nesting species on the incubation behavior of another. We also identified distinct differences between incubation constancy and nest attentiveness, indicating that these biparental incubating species do not share similar energetic constraints as those that are observed for uniparental species. Additionally, we found that variation in incubation behavior was a function of temperature and precipitation, where the strength of these effects was dependent on the time of day. Overall, these findings strengthen our understanding of incubation behavior and nest ecology of a colonial-nesting species. This dataset includes variables associated with nesting gulls (VICIN and GULL10).

Mobile Harbor Navigation Channel Delft3D Model Inputs and Results - Initial Project Conditions Grid

The numerical model Delft3D (developed by Deltares) was developed to evaluate the potential effects of proposed navigation channel deepening and widening in Mobile Harbor, Alabama (AL). The Delft3D model setup requires the input of a merged topographic and bathymetric elevations, a wave climate based on significant wave heights, peak wave period and mean wave direction, and a tidal-time series. The model was validated by comparing model outputs from deterministic runs with observations of water levels and velocities. The validated model was used to simulate scenarios of existing conditions and proposed with-project conditions (for example, channel deepening and widening). Simulations were performed for one year (the year 2010) and ten years, with and without 0.5 meters (m) of sea level rise. Model inputs and outputs in the form of topography and bathymetry for the scenario runs as well as output water levels and velocities for the deterministic runs are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to USGS Open-File Report 2018-1123.

Location and population served by domestic wells in California

This dataset identifies the number of individually-owned domestic wells, and the number of households relying upon domestic water supply in the state of California. The number of wells and households are summarized for each Public Land Survey System (PLSS) section. The well locations were determined from more than 635,000 scanned well-completion reports (WCRs) provided by the California Department of Water Resources in 2011. This is only a partial sample of the total number of WCRs (estimated at 1 to 2 million in total). The number of domestic wells was estimated based upon a spatially distributed and randomized survey that determined the Township Ratio (TR) for each township in the state (4,692 in total). Each township generally contains 36 sections (6 x 6). The total number of wells within a section was multiplied by the corresponding TR to estimate the number of domestic wells within each section. See the "TRatio" column in the attribute table. Each section within the same township will have the same Township Ratio. The domestic household data are from the 1990 US Census. These data were provided at the census tract level and were subsequently aggregated to PLSS sections that contained a domestic well. In the case where census tract data identified households using domestic supply, but there were no domestic wells within the tract, the household data were distributed evenly to all sections within the tract. In San Luis Obispo County, the scanned WCRs were incomplete. Therefore, a surrogate method was used. The total number of households reported by the 1990 census did not change; only the distribution of where those households existed within the tract changed. 
A WCR was considered an individually-owned domestic well if the primary use of the well was identified as being domestic, the owner was an individual, and the well was not destroyed as of 1990.  See the larger body work (Johnson and Belitz 2015) for more details.

Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Population Density from U.S. Block-Level Population Density Rasters for 2010

This tabular data set represents population density, persons per square kilometer from 2010 Census block level data, processed by James Falcone (USGS, 2016), compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data for population density was produced by the U.S. Geological Survey (Falcone, 2016). Units are persons per square kilometer. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).
