The bar compresses Elkhart's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 26–May 17 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 5. Wherever the today marker sits, the nearest color change is your next appointment.
