Nelson's Preseason Fishing Forecast
Mar 26, 2015
don’t know how many times we’re asked – at fishing shows, on the phone,
wherever anglers congregate – “How’s the fishing going to be this year?”
gazing into our crystal ball, here’s what we see:
the directly observables:
had warm dry weather during late winter, so hopes for additional precipitation
weren’t realized. The snow water
readings are at 50-75% of normal for this time of year.
holdover storage from last year was quite good, so Henry’s Lake is 100% full
and Island Park Reservoir is 90% full and filling. This means adequate, but low water levels for
the first part of the season.
weather and low water generally mean an early start to the seasonal hatches,
but unpredictable daily weather can change things from day to day. Overall, it looks like hatches could be a bit
early this year.
Day weekend comes early this year – May 23-25 – so earlier hatches should be a
welcome development for Opening Day and the early season.
numbers in the upper Henry’s Fork were at an extraordinary high in 2013 and
declined to close to the historic average during 2014, but the fishing was
outstanding, especially with good numbers of big fish. We hope that the numbers hold steady as there
should be plenty of large fish, but the impact of low flows this past winter
may have reduced the population somewhat.
the South Fork, the big reservoirs are 75-85% full and the snowpack close to
90% of normal, so water supply and conditions look more favorable for the
