In an attempt to settle unknown territory, the Mexican government offered a large gift of land, la merced, for anyone brave enough to attempt to settle the San Luis Valley. Mexican land grants made it possible for even a poor man to establish a homestead. The pobladores, or land grant settlers, lived a communal, self-sufficient lifestyle, on narrow strips of land called varas.
"Our land grant pueblitos, or little villages, always began with the establishment of our church, or iglesia, and plaza as the spiritual and cultural center of everyday life. Under the sharp eye and wisdom of the mayordomo, or ditch rider, we shared a system of 'acequias', or irrigation ditches, that watered our crops."
"Our vega, or common grazing land, supported our livestock and the foothills provided plenty of leρa, or firewood, and hunting. The acequias that our ancestors dug by hand over 100 years ago, still water our fields today."
The People of the San Luis Valley
Today, residents of the valley still claim to stumble upon the rock markers and wooden corner posts that were used to define the boundaries of the Mexican land grants.

The San Luis People's Ditch, or Acequia de la Gente, was established in 1852, making it the most senior water decree in Colorado. It has been in use since that time.
A 1911 drawing of varas illustrates how every parciante, holder of the water right, was given access to river or ditch water.
The partido, or sharing system, was a traditional way to manage livestock. The patrσn, or owner of the flocks, placed sheep in the care of a partidario, who took care of the sheep and was paid with a percentage of the lambs' wool he could produce.
