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.
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
The Henry’s Fork Foundation (HFF) has become aware of, and is actively investigating, the recent drawdown of Silver Lake in Harriman State Park. The sudden lowering of the lake released a large amount of fine sediment downstream into Thurmon Creek and the Third Channel of the Henry’s Fork through the Ranch. HFF was not informed before Silver Lake was drawn down. Fortunately, our science team was already in Harriman State Park and responded immediately, documenting

Guest Article by Mike Lawson, Henry’s Fork Anglers In early September, the Eagle Rock Wranglers, consisting of my youngest son, Chris, Mark Rockefeller (the owner of our business), Mike Engels, and Jonathan Lancaster won the 2025 Jackson One Fly event. It is a challenging accomplishment to finish at the top of the 40 team field. It was great to have some skin in the game again. I felt part of the winning team because I
