What The Pomperaug River Watershed Coalition Inc does
Mission
Prwc's mission is to protect, sustain, and restore the water resources of the pomperaug watershed through community engagement, education, advocacy, and science-based action.
As stated on its FY2025 Form 990.
Programs
Community outreach & education - the major objective for all of prwc's programs and activities is to underscore our collective roles as stewards of our environment and to promote good habits to keep our watershed and river healthy. Prwc achieves its education objectives through its classroom and field-based educational programs including workshops, presentations, seminars, and guided walks as well as traveling exhibits and collaborative outreach efforts such as earth day, river smart, and community event participation. Electronic and printed newsletters are distributed throughout the year and an informative website and social media presence are maintained.
$43,421 spent$5,504 earned by the program38% of program spendingScientific research, data collection, and protection and restoration projects - prwc collects, records, and studies environmental data including river flows, precipitation and weather conditions, water diversions and discharges, surface and groundwater quality, land use and land cover, stream and stormwater conveyance infrastructure, instream habitat conditions, aquatic flora and fauna, and stream temperature. The coalition compiles reports on and shares its findings to support water quality standard development, evaluation of local compliance with such standards, and to identify and implement pollution mitigation and habitat restoration measures. Prwcs work includes ongoing efforts to protect/restore water resources through river clean-ups, riparian buffer restoration projects, installation of rain gardens, and invasive plant removal.
$45,747 spent40% of program spendingResource management, planning, and coalition building - prwc accomplishes its mission by referencing the latest science to advance best management of the watershed and developing practical water management tools for the use of municipal, environmental and corporate partners, and private landowners. Resource management and planning includes developing strategies to mitigate stormwater runoff and non-point source pollution, preparing for impacts of flooding and drought, and lending data to inform water resource sections of local plans of conservation and development. Essential to the organizations success is building and sustaining the partnerships with local governments, businesses, private individuals, scientists, and environmental organizations who work collaboratively with regional, state, and federal agencies to protect the pomperaug watershed.

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 2023 to 2024, from $181k to $368k (+104%).
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: 2017 34% · 2018 34% · 2019 40% · 2020 34% · 2021 28% · 2022 33% · 2023 33% · 2024 22% · 2025 23%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 5 funders, grant income rose $35k → $40k.
4 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 96% 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 THE POMPERAUG RIVER WATERSHED COALITION INC’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
THE POMPERAUG RIVER WATERSHED COALITION INC leans on a few funders — its largest provides 91% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
96% 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 THE POMPERAUG RIVER WATERSHED COALITION INC.
Largest funder’s share by year: 2017 100% · 2018 99% · 2019 100% · 2020 95% · 2021 98% · 2022 98% · 2023 74% — diversifying over time.
“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.
How long its funders stay
60% of THE POMPERAUG RIVER WATERSHED COALITION INC's funders are still giving 3 years after their first grant; 44% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
96% of THE POMPERAUG RIVER WATERSHED COALITION INC'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 $14k that is directly attributable, 75% of it comes from funders outside Connecticut, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $310k arriving through sponsors registered in 4 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.
