Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch), extensively utilize small stream habitats influenced by a changing urban landscape. This study used a comprehensive fish health assessment concurrent with the U.S. Geological Survey’s Pacific Northwest Stream Quality Assessment in 2015 to quantifiy impacts from disease in juvenile coho and cutthroat salmon, impacts to...

Bathymetric and topographic data on the mainstem Nooksack River, Whatcom County, Washington were collected in the fall of 2015 as part of a study on sediment transport and channel change. Bathymetric data was collected from the river's mouth to river mile (RM) 28, near Nugent's Corner. Topographic data is available from RM 17, near the town of Lynden, to RM 37, near the confluence of the Middle Fork Nooksack. More information on these datasets is available in their respective metadata. The overlapping extents of these surveys were merged to create a seamless elevation data set of the river bed and active channel. Aerial lidar acquired in 2013 was used to fill in holes where vegetation prevented photogrammetric reconstructions...

These tables document grain-size distributions of sediment collected as part of a study on the geomorphic impacts of the March 2014 State Route 530 Landslide near Oso, Washington. This includes samples of material from the landslide deposit itself, covering a range of distinct facies present in the landslide, and samples of sand and gravel at various locations along the North Fork Stillaguamish River both upstream and downstream of the landslide. Grain size distributions of landslide material were distinguished between outwash material, till, and lacustrine material, distinct facies all present in the landslide deposit. Material coarser than 4-16 mm (sample dependent) was sieved and weighed in the field, and fine...

Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. Due to the photogrammetric methods used to collect these surveys, there may be substantial artifacts near the edges of the surveys, in areas of vegetation, or over extents of bare water, and should be used with caution in these areas. Details of the collection and processing of these data are provides in the overview metadata file.
