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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 6 reported years ran a deficit.
Who funds it, year by year
2017 → 2021: the base narrowed from 2 funders to 1 funder, grant income rose $60k → $156k.
2 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 44% 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 CALIFORNIA TROUT FOUNDATION’s funders (the co-funder graph). 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
CALIFORNIA TROUT FOUNDATION leans on a few funders — its largest provides 53% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
44% 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 CALIFORNIA TROUT FOUNDATION.
Largest funder’s share by year: 2017 83% · 2018 56% · 2019 100% · 2020 88% · 2021 100% — 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.
Where its funders are
99% of CALIFORNIA TROUT FOUNDATION's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $352k arriving through sponsors registered in 1 stateis 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.
