Fly fishing, Electrofishing, and More Fishing

Written in Late June

Now that all of the interns have arrived in Ashton, Idaho, the blogging can begin! I, Natalie, the Colgate intern, have been here for 5 weeks so far. Abi, the Ashton intern, has been working since April. Maya, the Washington and Lee intern, just finished her fourth week. Finally, Christina, the Stanford intern, has been here a week and a half.

 

Flows increasing to accommodate turbine testing: Be careful out there

The Henry’s Fork Foundation was notified in mid-June about plans to release water from the Island Park Reservoir to provide extra flows for a turbine test at Chester Dam June 21-26. Through negotiations with Fall River Rural Electric and other entities, it was decided to delay the release and the testing until later in July to provide more notice for travelling anglers and to maintain the great June angling opportunities on the Henry’s Fork.

Aquatic plant growth affects stream gaging

It's that time of year when growth of aquatic vegetation (called "macrophytes") begins to fill the stream channel and raise the water depth, even without changes in river flow. Remember that streamflow is the volume of water that flows past a given point on the river per time unit. We usually measure streamflow in cubic feet (volume) per second (time). The depth of the river (measured in feet) is a function of both streamflow and the shape of the stream channel. As macrophytes fill in the channel with plant biomass, there is less room for the water in the channel.

A day in the life of the Henry’s Fork - river flows and collaboration June 2015

Occasionally, I am asked what I do at the Henry’s Fork Foundation or what does the Foundation accomplish? The following synopsis of a day (OK, maybe two days plus) on the Henry’s Fork should give our members and the local community a little more insight to the daily work of HFF.

Plans beginning to take shape for future work on Harriman Canal and angler trails along the Henry's Fork

Plastic dams holding the Harriman Canal together November 2014

With the opening of the Ranch this week, it was time to get out a little bit of information about future projects that will enhance the experience of visitors to this hallowed water and protect the Henry's Fork and its wild trout.

Harriman Canal Project Overview

Help!

We need volunteers to help us clean our Adopt-A-Highway section of U.S. 20 in Island Park. We plan to meet Friday, May 22, at 10 a.m. at Elk Creek Station.We will have the necessary vests, trash bags, and safety signs. Please be sure to dress warm and bring gloves and a hat. We will also have bottled water on hand for our volunteers, and we'll spring for pizza afterward.

Thanks to our donors!

You did it! 102 of you donated $35,658.44 to the Henry's Fork Foundation during Idaho Gives on Thursday, putting us at No. 1 in total collections among all the charities! We are pleased to announce Eric Pauly won the Hyde Drift Boat so generously donated by LaMoyne Hyde and crew at Hyde Drift Boats in Idaho Falls. We can't thank you all enough for your generous support during this Idaho day of giving.

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?
