What Columbia Slough Watershed Council Inc does
Mission
The columbia slough watershed council brings community members together to enhance the health of the columbia slough and expand opportunities for people to enjoy this urban gem. We work to improve water quality, build and restore fish and wildlife habitat, increase public awareness and accessibility, empower youth, and advocate for a healthy watershed. Everything we do is possible thanks to the commitment of community members and engagement of local agencies, businesses, and partner organizations.
As stated on its FY2025 Form 990.

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 2022 to 2023, from $275k to $485k (+76%).
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 10% · 2018 78% · 2020 67% · 2021 74% · 2022 63% · 2023 60% · 2024 43% · 2025 63%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 9 funders, grant income rose $23k → $128k.

From the IRS filings of COLUMBIA SLOUGH WATERSHED COUNCIL 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
COLUMBIA SLOUGH WATERSHED COUNCIL INC has a broad base — no single funder exceeds 26% 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
51% 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 COLUMBIA SLOUGH WATERSHED COUNCIL INC.
Largest funder’s share by year: 2017 100% · 2018 59% · 2019 34% · 2020 53% · 2021 48% · 2022 34% · 2023 23% — 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.

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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $257k arriving through sponsors registered in 4 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.
