It has been a few years since I have seen this much early season fishing activity. From the start, March tilted a trend towards the warmest spring I can recall with several days approaching 70 and many more in the 50's & 60's, normal perhaps back east or in lower elevations but this is Jackson Hole, a place known for its lingering winters. Our current snowpack is around 82% and instead of growing from spring snows & rain it is quickly receding into the high country. This is fine , certainly for our early season activities, but can pose a potential late season dire situation with wildfires and dry drainages. Counter intuitively, dry, late season conditions bring high water on our most celebrated rivers, like the Snake of Jackson Hole and the South Fork in Eastern Idaho. The reason is as tributaries drop and agricultural lands dry the demand for water increases and the regulating bureaus step up outflow from these river's dams.
It has been a few years since we have seen a super hot summer, so I feel we are over due and might brace for just that. Until then we are enjoying a fantastic spring!
