What Clackamas County Historical Society does
Mission

Programs
In exhibits, We opened Jennings Lodge Camp: A Gathering Place for Faith, Community, and Revival, telling the story of the camps century-long role as a gathering place along the Willamette River. Nestled beneath a Cathedral of Trees, the camp welcomed families in faith and fellowship, as part of the national Camp Meeting Movement that began in the late 1700's. A special section also explores Oregon youth campssuch as Camp Meriwether, Camp Onahlee, and Camp Arrowheadcomparing their experiences to Jennings Lodge Camp. We launched a Museum Advisory Group and a Teacher Advisory Group to guide future exhibits and programs and began an oral history program by interviewing fourteen participants for the Jennings Lodge Camp Exhibit. Our exhibit team completed the first draft content of the upcoming Willamette River: Land, Culture, and History Exhibit, scheduled to open in Fall 2025.

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 2024 to 2025, from $1.1M to $969k (−15%).
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: 2019 9% · 2022 41% · 2023 31%. Grants only. Government contracts and fees sit inside program revenue.

1 of 10 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

the vertical line marks half of all grant income — 3 funders to its left
25% 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 Clackamas County Historical Society.
Largest funder’s share by year: 2017 94% · 2018 100% · 2019 95% · 2020 99% · 2021 65% · 2022 94% · 2023 98% — growing more concentrated.
“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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $47 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.
