Daily Accounting Calculations By Year
Season: Mar 1, 2026 - Oct 31, 2026
Unit Abbreviations: ac-ft, acre-feet; cfs, cubic feet per second; eod, end of day; eopd, end of previous day; °F, degrees Fahrenheit; in., inches
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval.
The Water Tracker's tracking equations were jointly developed by the Walker River Paiute Tribe, Bureau of Indian Affairs, and National Fish and Wildlife Foundation, with technical support from USGS in January 2014. Starting in the 2023 irrigation season, amendments were made to the original protocols by incorporating streamflow data from USGS 10301600 Walker River Above Weber Reservoir.
All values in cfs unless specified. Roll over type of water (such as Little Dam Gage) to see abbreviation. Negative net loss is a gain; positive net loss is a loss. Decree priority is set by the Federal Water Master and reported by the Walker River Irrigation District.
