The RGISC mission is to preserve, protect and foster respect for the Rio Grande~Rio Bravo, its watershed, environment and cultures through research, education and binational stewardship and alliances with individuals, agencies and organizations. Voice of the Rio Grande~Rio Bravo!

Chartered by the state of Texas in 1994, RGISC’s overarching goal is to act as a change agent and steward for the preservation and restoration of the environment of the Rio Grande Basin.
It pursues these goals through independent research, community education, and partnerships with governmental, educational, nonprofit and business entities on both sides of the Rio Grande.
RGISC was founded in response to growing concerns about the quality of the water supplied to the communities of the lower Rio Grande basin, and to study and provide science-based solutions to preserve the Rio Grande and its environmental heritage.
RGISC, meanwhile, has moved more strongly into public advocacy for endangered local ecosystems and habitats.

This binational celebration began in 1994 under the direction of the now-defunct Rio Grande/Rio Bravo Coalition, based in El Paso, TX.
The event is still celebrated by communities throughout the watershed, and celebrates the Rio Grande~Rio Bravo as it courses from the Rocky Mountains in southern Colorado to the Gulf of Mexico.
The river basin drains water from Colorado, New Mexico, Texas and the five Mexican states of Durango, Chihuahua, Coahuila, Nuevo Leon and Tamaulipas. Millions of people in the basin depend on the river for their existence.
The celebration, held the third Saturday of each month, has been kept alive by RGISC, and its sister organization in Nuevo Laredo known as CIER (Centro Internacional de los Estudios del Rio Bravo). RGISC and CIER members have performed clean-up and restoration efforts to aid this mighty yet threatened river, which has been listed among the 10 Most Endangered Rivers in the world, by the World Wildlife Fund.
Watershed education is vital for our area. RGISC now organizes a month-long calendar of exciting events for Dia del Rio during the month of October.
RGISC believes that investing and supporting these binational Día del Rio events and activities will translate into achieving many positive outcomes for millions of people in both countries that share the Rio Grande/Rio Bravo watershed.
