Alta Weir Wave


Description: The Alta Weir is one of several weirs between Pine Flat Dam and highway 180. The portage on river right is very easy.

This picture, from Spring of 1995 shows high water of about 13,000 cfs, when the river is legally closed to boating.

The smooth mound of water on the right or upstream side of the picture is the main part of the weir. There are concrete dividers spaced every 8 feet across the river. They are about 2 feet high. Each divider has a vertical slot on each side. Boards are slid down into these slots to dam the openings and raise the water level for a diversion on river left.

The boards are only useful for backing up very low flows, but in recent years they tend to get left in all year instead of just in late fall.
