Programs

Hff also has an archive to provide the public with pertinent historical context and data.

Hff also interacts with our membership and other watershed stakeholders through symposiums, field trips, hff hosted events and henry's fork watershed council meetings.
$2,203,780 spent100% of program spendingA healthy fishery starts with water. The amount of water and the quality of water in the river have a direct impact on fish and insect health, and our fishing experience.Collaborative Water ManagementTrout do not have water rights, so HFF must find ways to work within a system that affords us neither management authority nor decision-making power. What we do have, is data.HFFs science program collects, analyzes, and distributes data on the scale of a small university lab. It is our reputation as a source for reliable data that gets us a seat at the table where those crucial water management decisions are made. It is through partnerships, the Drought Management Planning Committee, and the Henrys Fork Watershed Council that HFF shares daily water reports and custom, predictive modeling to influence management for the benefit of wild trout.Water QualityHFF has also developed one of the most extensive water-quality monitoring networks run by a nonprofit in Idaho. With 12 sondes (underwater data collectors), a real-time data website, and an extensive water sampling protocol, HFF measures water temperature, dissolved oxygen, and water clarity parameters on a daily and weekly basis.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $2.7M to $3.3M (+22%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2024 16% · 2025 9%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 7 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 18 funders to 36 funders, grant income rose $151k → $444k.
17 of 75 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 34% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of HENRYS FORK FOUNDATION INC’s funders (the co-funder graph). Top 30 of 75 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
HENRYS FORK FOUNDATION INC has a broad base — no single funder exceeds 16% of grant income, and it takes 6 funders to reach half.
the vertical line marks half of all grant income — 6 funders to its left
40% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund HENRYS FORK FOUNDATION INC.
Largest funder’s share by year: 2017 17% · 2018 17% · 2019 23% · 2020 30% · 2021 19% · 2022 19% · 2023 47% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
54% of HENRYS FORK FOUNDATION INC's funders are still giving 3 years after their first grant; 71% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
HENRYS FORK FOUNDATION INC draws 95% of its grant income from funders outside Idaho, across 22 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.1M arriving through sponsors registered in 14 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
