Most of my code this summer starts with a river. Or snow. Or both.
Hi! I’m Eiman Jawwad, a rising junior at Stanford University, majoring in Computer Science with a minor in Environmental Engineering originally from Lahore, Pakistan. This summer, I’ve had the incredible opportunity to intern at the Henry’s Fork Foundation (HFF) in Ashton, Idaho — a place where cold, clear rivers meet powerful conservation work.
I’m working with the Henry’s Fork Foundation (HFF) as a Science & Technology Intern under the mentorship of Dr. Rob Van Kirk, HFF’s Senior Scientist. Working on a range of data-driven projects building and refining data systems that help monitor and model water flow, snowpack, and climate conditions across the Henry’s Fork and Upper Snake River Basin.
But it’s not just about the code (although there’s a lot of that). It’s about understanding the landscape, the science, and the people behind it.
In my first few weeks, I’ve been focused on improving the way the organization manages real-time and historical hydrologic and climate data. So far, I’ve expanded our daily data pipeline to include stream gages and reservoirs not just from the Henry’s Fork, but also from the South Fork of the Snake River and the Snake River headwaters. This expansion helps provide a more comprehensive view of regional water movement.
Lately, I’ve been working on integrating long-term climate datasets—some dating back to the 1980s—to support model calibration, hydrologic trend analysis, and long-term water availability assessments. It’s been rewarding to write code that doesn’t just run correctly, but that directly supports better decision-making in a complex and changing watershed.
While my work is grounded in code, some of the most unforgettable moments this summer have happened far from a screen. From casting a line into the Teton River on my very first fly-fishing trip to floating the crystal-clear waters of Big Springs, I’ve gotten to experience the ecosystems I’m working to understand through data. A field day at Harriman State Park gave me the chance to explore the zones I usually only see on a map.
These field moments have helped me understand the stakes of my work. It’s one thing to clean a time series on snowmelt—it’s another to stand where that snow used to be.
Living in the HFF intern suite with other interns has also added a sense of community to the summer — from late-night gaming & movie nights to trips into Yellowstone, it’s been a mix of learning, laughing, and exploring that I’ll never forget.
This isn’t the kind of summer where you’re sitting in an office all day writing tests. It’s a place where the work you do with code shows up in conversations about climate, conservation, and community. I came in wanting to understand how software could support environmental work—and I’m sure I will be leaving with a much deeper appreciation for what that actually looks like on the ground (and in the water).
It’s been a first-of-its-kind summer for me, and I know it won’t be the last time I try to bring systems and sustainability together. Grateful to be learning from the team at HFF—and from the rivers themselves.
As it is the afternoon of December 31, I am closing the year with my annual fish-of-the-month blog, this one at the end of my 11th year of catching a fish in my home waters in each month of the year. To spare you the math, that’s 132 consecutive months of catching a wild trout or whitefish (and in some years I’ve fair-caught suckers and shiners, too) within a three-hour drive of my home in
In this blog post, we 1) present our turbidity and suspended sediment data, 2) explain our suspended load calculations, and 3) provide some additional information justifying why we think that a substantial amount of bed load was transported into the Henry’s Fork in addition to the suspended load. Since first observing high turbidity in Thurmon Creek and the Henry’s Fork downstream associated with the Silver Lake drawdown in November 2025, HFF’s Science and Technology team
Written by Doris Squeri Tom and I met on our first day of grad school back in 1982. We were both broke and stressed, and we both loved the outdoors, so I decided that an affordable way to relieve some of that stress might be to learn how to fly-fish. We had learned to fish with our dads when we were very small, but it was bait fishing, and we wanted to try something new.
The Henry’s Fork Drought Management Planning Committee (DMPC) met on Monday, November 24 to set this winter’s outflow and reservoir-fill strategy for Island Park Reservoir—an annual decision with implications for winter trout habitat in Box Canyon and the Ranch. Winter Outflow: What’s Coming on December 1 Beginning December 1, outflow from Island Park Dam will increase, bringing winter streamflow through Box Canyon to ~380 cfs from December through February*. That equates to 76% of Box
