REMARKS - Water year 2014; no estimated daily discharges. Records good except for flows below 0.5 ft³/s, which are poor. Water year 2015; no estimated daily discharges. Records good except for flows below 0.5 ft³/s, which are poor. Water year 2016; no estimated daily discharges. Records good except for flows below 0.5 ft³/s, which are poor. Water year 2017; records good except for flows below 0.5 ft³/s and estimated daily discharges, which are poor. Water year 2018; records good except for flows below 0.5 ft³/s, and estimated daily discharges, which are poor. Water year 2019; no estimated daily discharges. Records good except for flows below 0.5 ft³/s. Water year 2020; records good except for flows below 0.5 ft³/s, and estimated daily discharges, which are fair. Water year 2021; records good except for flows above 500 ft³/s and below 0.5 ft³/s, and estimated daily discharges, which are poor. Water year 2022; no estimated daily discharges.
