On August 18, 2015, heavy rainfall triggered around 60 landslides in and around Sitka. These landslides moved downslope rapidly; several were damaging, and one demolished a home on South Kramer Avenue and killed three people. On September 16-18, 2019, the U.S. Geological Survey installed instrumentation at a site near the initiation zones of these landslides and other previous landslides on the west face of Harbor Mountain. The station consists of an electronics enclosure, a mounted rain gage, and two instrumented soil pits. Instruments record continuous...

Fine sediment particles represent a size range from 0.5-16.0 microns in suspended sediment and are the leading contributor of clarity reduction in Lake Tahoe. Model archive summaries document fine sediment particle surrogate models for the real-time calculation of fine sediment particles concentration at the Upper Truckee River at South Lake Tahoe, California. The methods used to produce the surrogate models follow U.S. Geological Survey (USGS) protocols as referenced...

Ordinary least squares regression equations were developed between suspended-sediment concentration and turbidity using the U.S. Geological Survey Surrogate Analysis and Index Developer (SAID) Tool (Domanski and others, 2015) and methods described in Rasmussen and others (2009). Model summaries were developed following guidance in USGS Office of Surface Water...

Seven slug tests, one single-well pumping test, and two multi-well pumping tests were conducted to evaluate properties of the Lahontan clays and silts, fluvial deposits, and coarser, water-bearing deposits of the Younger Alluvium. Data and analyses are presented in folders named according to type of test and aquifer analyzed, as described in the larger work.

The methods used follow USGS guidance in relevant Office of Surface Water/Office of Water Quality Technical Memoranda and USGS Techniques and Methods, book 3, chap. C4 (Rasmussen and others, 2009). The model is composed of two ordinary least squares linear regression equations covering low and high values of turbidity. The low turbidity equation is based on forty-one concurrent measurements of SSC and turbidity collected from October 1, 2016, through August 28, 2020; the high turbidity equation is...

Fine sediment particles in the size range of 0.5 to 16.0 micrometers (μm) represent the primary size range of suspended sediment responsible for clarity reduction in Lake Tahoe. Models will be used to create estimates of tributary fine sediment particles flowing into Lake Tahoe and to better understand the linkage of annual sediment loads and lake clarity.
