Headlines From Dr. Rob Van Kirk’s SWE report for the Henry’s Fork drainage filed yesterday.
- A little precipitation yesterday kept the water-year total at 115% of average.
- Snowmelt was very modest yesterday, keeping SWE around 2% below its annual peak.
- At an outflow of 271 cfs over the past week, Island Park Reservoir is 89% full and filling very slowly.
- A freshet operation designed to transport fine sediment out of the Island Park to Riverside reach will occur next Tuesday-Friday. See details on the Henry’s Fork Foundation website.
- We have posted a lot of information about the ecological benefits of the freshet, as well as information on other aspects of the freshet on the HFF web site and will continue to add to that information as the freshet approaches.
