Thinking About "The New Normal"

On Saturday, May 21st, Mike Lawson of Henry's Fork Anglers posted a well written blog about the changing conditions we're seeing on the Henry's Fork, or what may be "the new normal."  These changes are undoubtedly bringing new challenges for anglers and water managers alike. Mike's blog was posted on Facebook and got some comments and questions. Rob Van Kirk, HFF's Senior Scientist also wrote a comment in response to some of those comments and questions.

Buffalo River Fish Ladder: A Successful Spring So Far

In celebration of World Fish Migration Day, a day focused on restoring fish migration routes, and in recognition of the Buffalo River Fish Ladder as an integral piece for trout migration in the upper Henry’s Fork, I’m writing this blog to share information on what we are seeing so far this sampling season.

Snowmelt increase over weekend

In my blog on Friday, I gave a comprehensive review of the current status of snowmelt and runoff in the upper Henry’s Fork watershed. Despite cooler daytime temperature highs over the weekend, warmer nighttime lows and rain contributed to accelerated snowmelt between Friday and Monday. Both the Crab Creek and Island Park SnoTel sites report large decreases in Snow Water Equivalent (SWE) over the last few days, with both locations losing about 2 inches. Weekend weather left Crab Creek with 2.4 inches of SWE and Island Park with 1.6 inches.

Runoff, already?

With increased natural flow, elevated turbidity levels, and the disappearance of snowy horizons, runoff has signaled its arrival throughout much of the Henry’s Fork basin. Using Snow Telemetry (SnoTel) data, this blog will discuss how the current status of snowmelt and runoff in the Henry’s Fork headwaters compare to historic data and what this means for streamflow during the prime fishing time of mid- to late-June.

Turbidity in Perspective

During our regular water-quality monitoring last week, we observed that recent turbidity levels are above average in all reaches of the river, except below Island Park Dam, and the highest observed turbidity last week is higher than any observed turbidity below Island Park Dam since we started regular water-quality monitoring there in the summer of 2013. The highest turbidity levels we observed last week were in the Warm River-to-Ashton Reservoir reach (18 NTU) and at Pinehaven (9 NTU).

Projected Springtime Management of Island Park Reservoir

The Island Park Drought Management Planning Committee met on April 8 to discuss projected water supply and management of Island Park Reservoir this spring. Organizations represented at this meeting were Fremont-Madison Irrigation District, North Fork Reservoir Company, Fall River Rural Electric Cooperative, Idaho Department of Fish and Game, The Nature Conservancy, U.S. Bureau of Reclamation, Water District 01, and Henry's Fork Foundation.
