What Rgisc Inc does
Mission
To preserve and protect the rio grande-rio bravo, its watershed and environment, through awareness, advocacy, research, education, stewardship and bi-national collaboration for the benefit of present and future generations. In 2023, the rio grande international study center (rgisc) undertook numerous impactful projects across environmental advocacy, water security, air quality, and community engagement. These initiatives, supported by dedicated staff, volunteers, and partners, furthered rgisc's mission to protect the rio grande and promote environmental justice along the u.s.- mexico border. Below is a detailed summary of rgisc's accomplishments across exempt purpose categories.
As stated on its FY2024 Form 990.
Programs

Youth & community in nature (ycn) summer eco-camps hosted immersive week-long camps at lake casa blanca and local natural spaces, providing hands-on steam learning, kayaking safety instruction, wildlife and ecology lessons, and environmental stewardship activities to develop young conservation leaders. Spring eco-camps piloted spring break nature days offering structured field education, including watershed science, wildlife identification, beginner paddle skills, and place-based storytelling to expand year-round access to outdoor learning for youth and families. Rrr rio research roundup the rio research roundup, established in 2010, is one of rgiscs longest- running environmental education programs and remains the only binational, basin-wide student water-testing initiative along the rio grande/rio bravo. Over the past decade, thousands of students from texas, new mexico, and northern mexico have participated, gaining scientific field experience and building river stewardship across the watershed.

2. Agua river monitoring (texas clean rivers program) rgisc has served as a core partner in the texas clean rivers program since its inception in 1994, making this our longest-running scientific monitoring initiative. For over 30 years, staff have collected monthly water samples along the rio grande to track e. Coli, salinity, metals, and other indicators, providing one of the most consistent and comprehensive datasets for border-region river health. This long-standing partnership supports state water-quality decision-making, informs public health understanding, and strengthens binational coordination to protect the river for current and future generations. Agua general activities facilitated coordination with research institutions, city partners, and engineers on drought mitigation, wastewater reclamation, aquifer storage and recharge, and long-term water supply strategies, advancing local and regional water-security planning.

Pachanga el azteca we held multiple community gatherings with the residents of barrio el azteca to co-design environmental priorities with residents, including native tree planting strategies, invasives removal, neighborhood improvements, and heat-resilience activities in this highly disadvantaged but historic neighborhood. Pachanga la ladrillera we facilitated various listening sessions and mapping activities to identify infrastructure gaps, public-space needs, and stormwater access barriers, grounding climate planning in community experience in this riverfront neighborhood.

$941,897 spent100% of program spending
The 4 programs described on its FY2024 Form 990, listed largest first by expense. Program spending in total: $941,897.
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 2022 to 2023, from $397k to $914k (+130%).
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 10% · 2019 7% · 2020 26% · 2021 36% · 2022 13% · 2023 25% · 2024 10%. Grants only. Government contracts and fees sit inside program revenue.
90% of RGISC INC’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 7 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 18 funders, grant income rose $85k → $1.3M.
12 of 33 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 19% 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 RGISC INC’s funders (the co-funder graph). Top 30 of 33 funders by total. 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
RGISC INC has a broad base — no single funder exceeds 15% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
75% 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 RGISC INC.
Largest funder’s share by year: 2017 88% · 2018 100% · 2019 100% · 2020 40% · 2021 41% · 2022 28% · 2023 38% — 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
45% of RGISC INC's funders are still giving 3 years after their first grant; 61% 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
RGISC INC draws 58% of its grant income from funders outside Texas, across 8 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $665k arriving through sponsors registered in 6 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.
Against its field
