Intake Diversion Dam
This drawing shows a cross section of the proposed concrete weir that would be constructed upstream from the existing rock ramp.
Creating a twisting, 3-mile-long channel around Intake Diversion Dam on the lower Yellowstone River to allow endangered pallid sturgeon and other native fish to swim around the dam would cost an estimated $58.9 million and the moving of more than a million cubic yards of dirt and gravel whil…

A 126-page document that contains or references most of what is known about the endangered pallid sturgeon in the Missouri and Mississippi rivers has been completed and released to the public.

Delays in the design and budget approval for rebuilding the Intake Diversion Dam have set back the project, which was projected to start in 2011.
A new headgate and fish screens were built to replace this one on the Lower Yellowstone Project, 16 miles downstream of Glendive.
By Thursday, steady rains over four days had boosted the Yellowstone River at Glendive by 10,000 cubic feet per second. That flush of water was a powerful enticement for paddlefish that move up the river every spring from Lake Sakakawea in North Dakota to spawn.
In the past 20 years, scientists have gained a wealth of knowledge about the pallid sturgeon’s life cycle and feeding habits and the best ways to raise young pallids in hatcheries.
Federal and state officials will gather Monday to dedicate the new irrigation headworks for the Lower Yellowstone Project north of Glendive, at least five years in the making.
Still to be worked out is how the Army Corps of Engineers will figure out how to allow native fish, like endangered pallid sturgeon, to swim around the Intake Diversion Dam. The dam creates a popular spring paddlefish fishery, which opens in May.
The U.S. Army Corps of Engineers' schedule to reconstruct Intake Diversion Dam on the Yellowstone River has been delayed as the agency refines its design.
As the project to remove Intake Diversion Dam on the Yellowstone River and rebuild it moves forward, there are a couple of unsettling possibilities lurking.
This undated photo shows the Main Canal's headworks being constructed in the early 1900s as part of the construction of the Intake Diversion Dam.
The $36.5 million project to remove and rebuild the Intake Diversion Dam on the Yellowstone River is expected to also aid in the passage of other native fish, such as sauger and paddlefish. The loss of an estimated 577,000 fish into the canal each year could be reduced.
