 Ice Harbor Lock and Dam - Lake Sacajawea Overview

Ice Harbor Lock and Dam is 2,822 feet long and 100 feet high. It is of the concrete gravity type, with an earth-fill embankment section at the north abutment. It has a ten-bay spillway that is 590 feet long, and ten, 50-foot tainter gates. There are two fish ladders for passing migratory fish.

When full, Lake Sacajawea extends northeast 32 miles upstream to Lower Monumental Dam, and has a surface area of 9,200 acres. 

 Ice Harbor Campgrounds

A variety of recreation opportunities such as fishing, swimming, picnicking, boating, hunting, hiking and camping are available around Ice Harbor Dam and Lake Sacajawea. Each of these parks has a day-use picnic area.

All campers must check in with the campground attendant upon arrival. The placement of camping equipment or other items on a site for the purpose of reserving the campsite for future occupancy is strictly prohibited.

 Public Lands

There are 3,576 acres of public lands surrounding Lake Sacajawea. These lands include fee lands that are federally-owned and managed by the Corps, as well as easement lands to which the Corps has specific rights or easements (i.e., flowage or access). There are 3,517.3 acres of Corps-managed lands that are utilized for public recreation purposes, wildlife habitat, wildlife mitigation, and water-connected industrial development. Public boat launching facilities are available at six locations along the shoreline, and there is a marina at Charbonneau Park.

 Navigation Lock

The lock is a single-lift type with clear plan. It has clear dimensions of 86 feet by 675 feet, and a 15-foot minimum depth.

CAUTION: Ice Harbor Dam's forebay restricted area has been relocated which has set further limitations to boater access near the upstream end of the dam. For more Navigation information see our page at

 Hard Rock Mooring Dolphins
The Hard Rock Dolphin Mooring Facility consists of six mooring dolphins located one mile upstream from the dam. Because navigation is sometimes limited at the lock, the mooring dolphins are used during inclement weather to tow barges to safety, as well as temporarily moor barges from broken tows. The dolphins were installed in 1973, and three of the original dolphins have been replaced. In 1986, minor repair work was performed on all six dolphins.
