Delagua is an extinct town in Las Animas County, Colorado, United States.

[10] By 1916, the saloon and dance hall had been converted into the Delagua Social Club, complete with "three first class pool tables and one billiard table", a soda fountain, bowling alleys, a stage that featured a motion picture show twice weekly and, at least, 250 members, in 1917.

[10] At the Delagua Mine on November 8, 1910, an explosion (loud enough to be heard three miles away in Hastings) killed 76 miners.

Safety inspectors later determined that the blast was an explosion of gas and dust, caused by the open flame of a head lamp.

[14][15][16] A Colorado House of Representatives subcommittee heard testimony that strikebreaking workers were lured to the Delagua mine, under false pretenses, and held there by force.
