Conservation and Maintenance: Over two hundred people participated in ten volunteer workdays in 2024, coordinated by WWGC. Primary activities were picking up litter, cleaning and repairing amenities, painting, weeding and mulching, watering, trimming, and planting trees. Three Eagle Scouts completed projects in 2024, including installing bird houses, adding safety signage, and refurbishing trails. Conservancy members also contributed thousands of hours on repairs, eliminating graffiti and illegal dumping, providing security and organizing workdays, scout projects, and community events.

These include construction of eight miles of ADA all-weather trails, four new parking areas, five safe street crossings, and fifty wayfinding signs. Over 1000 trees and fifty new benches/tables along trails were installed. Capital projects reported as in progress in 2023 were completed in 2024. Slated for completion in 2025-2026 is the environmentally sensitive development of the fifteen-acre Native Prairie Preserve with a boardwalk and educational signage. These infrastructure improvements restore and sustain the ecological health of the environment while providing public access to a much-needed natural setting in an urban/industrial area.

The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 2021 to 2022, from $2.1M to $6.9M (+228%).
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: 2024 62%. Grants only. Government contracts and fees sit inside program revenue.
88% of Willow Waterhole Greenspace Conservancy Inc’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $29k arriving through sponsors registered in 2 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.
