What CSH2O Charitable Foundation Corporation does
Mission
The Organization creates and offers hands-on programs and experiences for the community and youth that are designed to inspire a passion for Maryland's waterways, and connect them with one of the State's most cherished resources.
As stated on its FY2025 Form 990-EZ.
Programs
The Organization provides Oyster & Environmental Education lessons to schools and communities in several counties in Maryland. These authentic programs and experiences are designed to inspire a passion to preserve and protect Maryland's waterways. We believe that environmental stewardship is a lifelong pursuit that starts with providing education at a young age to help students understand their impact on the environment and instill a lifetime of respect for our waterways. In 2025, we provided programs to 235 classrooms/community events and reached 6,250 students.

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 $15k to $57k (+281%).
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.
91% of CSH2O Charitable Foundation Corporation’s revenue is contributions — about as donation-reliant as the typical peer (95% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 5 reported years ran a deficit.
Who funds it, year by year
2017 → 2022: the base held at 1 funder, grant income held at $5k.
4 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 66% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

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
CSH2O Charitable Foundation Corporation leans on a few funders — its largest provides 34% of grant income and the top three 80%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
89% 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 CSH2O Charitable Foundation Corporation.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 64% · 2021 71% · 2022 100% — broadly stable.
“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
66% of CSH2O Charitable Foundation Corporation'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 $30k that is directly attributable, 66% of it comes from Maryland funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $58k arriving through sponsors registered in 3 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.
