Rio Grande Basin Roundtable

Next Basin Roundtable Meeting

November 9, 2021

2:00 - 5:00pm

View Details

The Rio Grande Basin encompasses approximately 8,000 square miles, including the San Luis Valley. This high mountain valley extends approximately 90 miles from north to south and 50 miles from east to west. Water in the Rio Grande Basin is currently over appropriated (and has been since the 1890s). All of the waters of the Rio Grande and Conejos River and their tributaries are subject to the terms of the Rio Grande Compact. The Valley’s groundwater resources have been over drafted and the areas face depleted groundwater levels throughout much of the basin. By 2050, a total shortfall of 180,000 acre feet (AF) is expected, of which 160,000 AF is the agricultural groundwater shortage to be addressed by pending SEO rules and regulations and fallowing land via the Groundwater Sub-district.
