    "descript": "This data release includes grain-size data from sediment samples collected in submerged and subaerial regions in Whiskeytown Lake and around the reservoir margin. Sediment samples were collected using a sampler deployed from a boat or by hand from locations exposed above the water surface. Sediment grain size was analyzed at the USGS laboratory in Santa Cruz, Calif. The full data set is reported here, but users should be aware that due to instrument error the data between approximately grain sizes from 0.040 to 0.063 mm may be incorrect and have unknown degrees of uncertainty. Proportions of gravel, sand, silt, and ratios among these size fractions, are considered accurate.",

This category does not include energy resources, which are discussed previously. Distributions are recorded observations, interpreted data, or models of specified resources at known times and locations and can include added tangible information for the resource in question (for example, thickness of deposit). Assessments are evaluations of total resource availability, economic value, ecological function and value, drivers, difficulty of extraction, and sustainability; larger assessments that combine Resources and Uses categories can appropriately be included both here and in the other related Resources or Uses categories. Predictions are the results of models or projections of future distributions, values, or impacts of material resources; these data include modeled changes to resources due to natural and human processes. Examples include models of resource losses or gains under different rates of resource extraction, deposition, natural removal, and accumulation; models of how changes to one resource can affect other resources or uses; and models that compare outcomes of different management actions."
