electrofishing

Idaho Fish and Game will be electrofishing on two stretches of the Henry's Fork over the next two weeks. They will be electrofishing the Vernon-to-Chester stretch on May 6, 7, and 14, and Box Canyon on May 11, 12, and 18.  All dates are pretty firm barring any unforeseen equipment issues or weather conditions (e.g. lightning).

Monitoring Juvenile Trout Numbers in Fish Creek (Harriman East)

Personnel from the Henry’s Fork Foundation (HFF), U.S. Forest Service (USFS), and Brigham Young University-Idaho (BYUI) conducted an estimate of juvenile trout abundance in Fish Creek on April 15-16, as part of a long-term restoration and monitoring effort. How did our 2015 numbers compare with those in 2011, prior to major restoration of the creek?

Spring of 2015 shaping up to be driest in last 35 years

April 1 is an important date in water management in the western U.S. because it is the typical date of maximum water content in the snowpack at most mountain locations. Based on yesterday's data, I predict that April-June streamflow in the Henry's Fork at Island Park this spring will be the lowest in the last 35 years and possibly the lowest since the extended drought of the 1930s. And that's no April fooling.

Business Partners of the Henry's Fork Foundation - Volume 1 of Many: Loop USA

Here at the Henry’s Fork Foundation we are fortunate to have many generous donors. We are also fortunate to have business partners that donate in conventional and unconventional ways to help us expand our fundraising efforts and accomplish more projects to benefit the river. While I am may not keep the clockwork schedule Rob Van Kirk does with his Friday blogs, I am going to attempt to write recognition pieces a couple of times per month.

HFF adds high-tech invertebrate sampling to water-quality network

Last week, aquatic invertebrate experts David Richards and Brett Marshall met us on the river to kick off an exciting new project that will allow HFF to monitor numbers and types of aquatic insects and other invertebrates using DNA “bar-coding”. Former HFF Board Chair Robert Dotson joined us for part of the day.

The 2014 Annual Report is now available online

The Henry's Fork Foundation's 2014 Annual Report has just been posted online. It contains reports and photos of our major projects plus a list of the hours and money we spent on projects in 2014. A special pull-out section chronicles the first 30 years of the Foundation to commemmorate our 30th anniversary. We listed our donors for the year, including the new Legacy Society of those who have remembered the Foundation in their estate planning. And you can read what some folks said when we asked them what kind of impact the Foundation made in its first 30 years.

Implications of irrigation seepage for fisheries management

I’ve been traveling much of the past two weeks and haven’t had time to post a blog lately.  This week’s post is the presentation I gave at the Idaho Chapter American Fisheries Society meeting in Boise on March 4.

Here is a link to the slides, in pdf format. An explanation of each slide is given below.

Teasers from our 2014 Angler Attitude Survey

As most of you know, HFF conducted a survey of anglers in Harriman State Park (“the Ranch”) in 2014. The survey was identical to one conducted back in 2008, for direct comparison of angler attitudes and experiences between the two years. In 2008, the (new, improved) Buffalo River fish ladder and the Island Park Drought Management Planning process were each only two years old and so had not had time to fully affect the population of rainbow trout available to anglers. By 2014, two full fish generations had passed since implementation of these two major fishery improvement projects, and we went back to see whether anglers had noticed any difference in the fishing.
