This reference is referred to as Zamora-Reyes and others, in review in the text. This data release includes the revised downscaled climate inputs and hydrologic outputs from the Basin Characterization Model (BCM) version 8 (v8), described in Flint and others (2021a), in a 30 by 30-meter spatial resolution at a monthly time step from water years 1896 to 2024 for the upper Feather River watershed. This data release includes five child items: 1. 30-year summaries, 2. Model Archive, 3. Monthly BCM hydrology variables, 4. Monthly climate variables, and 5. Water year summaries. VERSION HISTORY: Revised: February 27, 2026; Data release corrected to fix error in the original model parameters. First posted: March 25, 2025 at https://doi.org/10.5066/P1QA5FLG (deprecated data release) REVISED: The Basin Characterization Model was run to produce fine-scale gridded estimates of actual evapotranspiration, soil moisture, recharge, runoff, and other water balance components. These are natural estimates of the water balance components and do not reflect anthropogenic factors like irrigation, diversions, and other water management decisions. 18951001 20240930 ground condition Complete None planned -121.5992 -120.1005 40.5051 39.4865 Upper Feather River watershed, Plumas, Butte, Sierra and Lassen Counties ISO 19115 Topic Category climatologyMeteorologyAtmosphere environment geoscientificInformation inlandWaters USGS Thesaurus Hydrology Surface Water (non-marine) Atmospheric and Climatic Processes Water Cycle Evaporation Transpiration Streamflow Mathematical Modeling Water Budget Water Resources Watershed Management Precipitation (atmospheric) Snow and Ice Cover Soil Moisture Permeability Modeling USGS Metadata Identifier USGS:686f08f2d4be020e5c01cbbe Common Geographic areas California United States None.

Downscaled climate inputs and hydrologic outputs in this data release are separated into five child items: 1. 30-year summaries: water year files that include average (aves) and standard deviation (stdev) for each of two 30-year periods, 1981-2010 and 1991-2020, and zipped by each of ten climate and hydrology variables: minimum temperature (tmn), maximum temperature (tmx), soil storage (str), runoff (run), recharge (rch), precipitation (ppt), potential evapotranspiration (pet), snowpack (pck), climatic water deficit (cwd), and actual evapotranspiration (aet), resulting in a total of 20 zipped folders. 2. Model Archive: includes zipped Input and Output files, zipped Source code, model georeference, and ReadMe file with instructions on how to run model. 3. Monthly BCM hydrology variables: monthly BCM hydrology variables zipped by decade constituting of 14 zipped folders for each of the 6 variables (described in 1., above), for a total of 84 zipped folders. 4. Monthly climate variables: four monthly climate variables zipped by decade constituting of 14 zipped folders for each variable, for a total of 56 zipped folders. 5. Water year summaries: monthly files summed for each of the 8 variables (aet, cwd, pck, rch, run, str, pet, and ppt) or averaged for the two temperature variables (tmn and tmx) by water year, zipped by variable from 1896-2024, for a total of 10 zipped folders. Each zipped folder has a similar naming convention xxx_WYYYYY_YY, where: 1. YYYY indicates four digit year 2. With variable names: aet, cwd, pck, rch, run, str, pet, ppt, tmn, tmx Files within those zipped folders have a structure, where: 1. YYYY indicates four digit year 2. mmm indicates three letter text abbreviation of month (from January-jan to December-dec) 3.
