Another huge milestone was met on site this month when the main dam hit elevation 5699.5 feet, which is the halfway mark to the eventual 350-foot-tall main dam. The asphalt core dam reached 175 feet on March 23. 

To date, approximately 6 million cubic yards of rockfill and 25,000 cubic yards of hydraulic asphalt have been placed on the dam, all of which came out of the on-site quarry.

As the dam rises, the asphalt core placement becomes longer and the rockfill placement becomes narrower. As of mid-March, it takes about six hours to complete one 9-inch lift of asphalt running about 2,300 feet from end to end. The asphalt core paver moves at about 7 linear feet per minute (0.08 miles per hour) placing both zone 1 (hydraulic asphalt) and zone 2 (2-inch and smaller crushed stone) simultaneously. 

Crews are resuming summer hours of two 12-hour shifts, six days a week. This change comes a little early due to favorable weather. The main dam is expected to be complete in late summer 2025.
