What River Partners does
Mission
River Partners mission is to bring life back to rivers by creating wildlife habitat for the benefit of people and the environment. We envision interconnected, thriving floodplains that sustain abundant wildlife, support productive farmland, preserve freshwater resources.
As stated on its FY2025 Form 990.
Program
Performed river and floodplain-restoration planning, implementation, and management projects with state and federal partners such as the california department of water, california department of fish and wildlife, wildlife conservation board, u.s. Bureau of reclamation, and u.s. Fish and wildlife service. Initiated the acquisition of floodplain lands for future restoration on hundreds of acres in northern california, the central valley, and southern california. River Partners continued the active restoration of thousands of acres statewide along major california waterways such as the sacramento, feather, san joaquin, tuolumne, stanislaus, kern rivers. Dozens of imperiled and endangered wildlife species benefitted from our work, including iconic salmon, migratory and resident birds such as the least bell's vireo, and mammals such as the riparian brush rabbit. Numerous communities in which we worked this year benefitted from increased job opportunities and restoration funds going to local economies, reduced flood risk, recharged groundwater, and increased recreational opportunities. River Partners also served local communities throughout california by participating in multiple public…

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. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $27M to $44M (+61%).
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: 2017 45% · 2018 33% · 2019 65% · 2020 21% · 2021 24% · 2022 30% · 2023 77% · 2024 40% · 2025 54%. Grants only. Government contracts and fees sit inside program revenue.
67% of RIVER PARTNERS’s revenue is contributions — about as donation-reliant as the typical peer (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 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 4 funders to 8 funders, grant income rose $154k → $293k.
7 of 28 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 16% 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 RIVER PARTNERS’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
RIVER PARTNERS has a broad base — no single funder exceeds 31% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
80% 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 RIVER PARTNERS.
Largest funder’s share by year: 2017 58% · 2018 53% · 2019 75% · 2020 49% · 2021 28% · 2022 63% · 2023 34% — diversifying over time.
“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
78% of RIVER PARTNERS's funders are still giving 3 years after their first grant; 50% 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
RIVER PARTNERS draws 81% of its grant income from funders outside California, across 9 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.2M arriving through sponsors registered in 7 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.
