What Waddell Creek Association does
Mission
The Waddell Creek Association in cooperation with california state parks provides public access to the coastal section of big basin redwoods state park. We showcase the environmental, cultural and historical gems of the seashore, marsh and lower forested area including many flora and fauna unique to these areas. We also support interpretive programs, outdoor classroom events and the new wilderness patrol project. Incorporating information on fire ecology, climate change and the interaction between humans and nature as well as highlighting the historical tending and foraging of indigenous cultures has been added to our overall education efforts. Our aim is to include everyone in this education as we are all citizens of this planet and every action (or non-action) affects us all. The interpretation of nature is vital if we are to make positive impacts for future generations.
As stated on its FY2025 Form 990-EZ.

In addition, there were developments in our website and online presence to enhance the exposure of our activities to the community at large and maintenance of security to provide the best possible protection in the web world and a qr code for ease of purchase. Events included salamander saturday (a scaled-down version of self-directed activities), wildflower weekend and event/program support in the form of supplies (nature journals, pencils, watercolor sets, chair rental and t- shirts). Diane west-bourke, a long-time volunteer with hulda hoover, gave history training to volunteers from rdo and ano and a major effort was made to start sorting/ preserving the archive materials stored there. We also had hulda hoover day to celebrate the life and activities of this amazing woman who founded the Waddell Creek Association. There were speakers, guided walks and workshops provided. Wca purchased a water bottle filling station for the…

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.
Balance sheet
Total assets at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $56k to $77k (+37%).
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.
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
2019 → 2023: the base narrowed from 2 funders to 1 funder, grant income fell $18k → $23.
3 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 37% 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 WADDELL CREEK ASSOCIATION’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
WADDELL CREEK ASSOCIATION leans on a few funders — its largest provides 63% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
37% 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 WADDELL CREEK ASSOCIATION.
Largest funder’s share by year: 2019 67% · 2020 88% · 2022 100% · 2023 100% — 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.
Where its funders are
WADDELL CREEK ASSOCIATION draws 100% of its grant income from funders outside California, across 2 states in all.
Funder states come from each funder’s own filing. $23k 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.
