What Massachusetts Rivers Alliance Inc does
Mission
The mission of our organization is to protect and restore Massachusetts rivers and streams.
As stated on its FY2024 Form 990.
Program
The MassachusettsRivers Alliance was formed to protect rivers and streams in Massachusetts by developing and encouraging practical, effective policy for a sustainable future. In 2024, Mass Rivers taught over 500 people about dam removal to accelerate the pace of river restoration in Massachusetts. The organization helped secure over $14M in increased investment in state agencyprograms that protect and restore rivers. The organization also connected and strengthened over 80 member groups through monthly and bi-monthly peer-to-peer meetings, moved its top priority (known as "the drought bill") closer to passage, and stopped several harmful legislative initiatives. Mass Rivers represented water interests on over 30 committees, commissions, task forces, and advisory groups.

The program described on its FY2024 Form 990. Program spending in total: $363,700.
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 2020 to 2021, from $252k to $755k (+200%).
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 1%. Grants only. Government contracts and fees sit inside program revenue.
99% of Massachusetts Rivers Alliance Inc’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 10 funders, grant income rose $6k → $224k.
10 of 24 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 74% 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 Massachusetts Rivers Alliance Inc’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
Massachusetts Rivers Alliance Inc has a broad base — no single funder exceeds 28% 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
74% 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 Massachusetts Rivers Alliance Inc.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 77% · 2020 28% · 2021 74% · 2022 54% · 2023 45% — 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
36% of Massachusetts Rivers Alliance 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
74% of Massachusetts Rivers Alliance Inc's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $373k that is directly attributable, 62% of it comes from funders outside Massachusetts, across 7 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.1M arriving through sponsors registered in 6 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.
