Most data were collected along the same transects where channel topography was measured (see related child item in this data release: https://www.sciencebase.gov/catalog/item/5a989288e4b06990606de04b). Measurements of sediment ranging from medium sand to boulders were made using the CobbleCam digital photographic technique (Warrick and others, 2009), which uses a calibrated autocorrelation algorithm (Rubin, 2004) to calculate the mean grain size of sediment from pixels in downward-looking digital photographs. This technique yields grain-size values accurate to within 14 percent of those obtained by pebble counting (Wolman, 1954; Warrick and others, 2009). For samples finer than medium sand, we measured grain size using a Coulter laser particle-size analyzer at the USGS laboratory in Santa Cruz, California. Grain size was measured along subaerial portions of the survey transects within the bankfull channel. We also measured grain size of some sediment deposited after dam removal that did not coincide with survey transects (these sample locations are labeled “OffTransect” in the data file).

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.

Lineage: Process_Step: Process_Description: Measurements on sediment ranging from medium sand to boulders were made using the CobbleCam digital photographic technique (Warrick and others, 2009), which uses a calibrated autocorrelation algorithm (Rubin, 2004) to calculate the mean grain size of sediment from pixels in downward-looking digital photographs. This technique yields grain-size values accurate to within 14 percent of those obtained by pebble counting (Wolman, 1954). For samples finer than medium sand, we measured grain size using a Coulter laser particle-size analyzer at the USGS sediment laboratory in Santa Cruz, California, after removing any organic matter with a hydrogen peroxide solution. Grain size was measured along subaerial portions of the survey transects within the bankfull channel. We also measured grain size in parts of the study reaches containing new sediment deposits (after dam removal) that did not coincide with survey transects, collecting enough additional data in such cases to avoid spatial bias and ensure that grain-size measurements represented both the newly deposited material and any older sediment still exposed. In such cases, the data are coded as "OffTransect." Process_Date: 2017 Process_Step: Process_Description: Corrected name of theme keyword thesaurus from ISO 19115 Topic Categories to Category.
