The bar compresses Rio Rancho's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 15–May 6 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 21. Wherever the today marker sits, the nearest color change is your next appointment.
