Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
11/10/2018 11/13/2018 7:00 AM 4 1.62 0.0 0.00 Distribution was approximately 0.5 on 10th and 1.1 on 13th with two zero days in between.
11/16/2018 11/27/2018 7:00 AM 12 2.85 0.0 M Catch in outer cylinder was actually 2.81 but added 0.04 to adjust for evaporation as the inner cylinder and funnel were removed for this eleven day absence.
12/15/2018 12/17/2018 7:00 AM 3 3.25 0.0 M Rain, heavy at times, spanned these three observational days. Accumulation in open-mouthed outer cylinder was actually 3.21 but allowed for 0.04 of evaporation.
12/21/2018 1/01/2019 7:00 AM 12 2.80 0.0 M Actual content was 2.60 but added 0.20 for evaporation as catch sat for up to 12 days in open-mouthed outer cylinder, and 2.80 is in "ballpark" with neighboring reports which show little variance.
