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.
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: 2018 56% · 2019 74% · 2021 82% · 2022 77% · 2023 78% · 2024 65% · 2025 55%. Grants only. Government contracts and fees sit inside program revenue.
78% of PENNSYLVANIA LAKE MANAGEMENT SOCIETY’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).

Who funds it, year by year
2020 → 2023: the base held at 1 funder, grant income fell $19 → $18.
1 of 1 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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 PENNSYLVANIA LAKE MANAGEMENT SOCIETY’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.
Where its funders are
100% of PENNSYLVANIA LAKE MANAGEMENT SOCIETY'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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $88 arriving through sponsors registered in 1 state 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.
