	DNR - Berrien Springs Fish Ladder
		It is the first dam that fish need to negotiate a ladder to continue their upstream migration.
		Competed in 1975 at a cost of $692,500, it was the 2nd major fish ladder completed in the state after the completion of the 6th Street Dam fish ladder on the Grand River in Grand Rapids, Michigan.
		This is the only ladder on the St. Joseph River that is a pool-weir since it allows for a sea lamprey barrier in its design.

	Salmon Navigating Fish Ladder - Video - MSN Encarta (Site not responding. Last check: )
		Fish ladders provide salmon and other migratory fish species with a way to navigate around large dams.
		Even with the aid of fish ladders, however, many fish are unable to circumnavigate large dams.
		Fish that cannot bypass the dams typically die before they are able to reproduce.

	AFRP - Daguerre Point Dam fish ladder modification, diversion improvements- Feasibility study and preliminary ...
		Passage improvement options that will be evaluated include structural modification to the fish ladders and the dam spillway to maintain appropriate adult and juvenile salmonid passage conditions; complete reconstruction of one or both fish ladders to allow adult passage under a greater range of flows; and dam removal.
		Additional fish screen evaluations and modification options, subsequent to initial engineering consideration for the fish ladders must be coordinated through the AFSP and the respective irrigation districts and the Yuba County Water Agency (YCWA).
		Modification to the existing fish ladders, construction of new ones, or dam removal would clearly improve the ability of migrating salmonids to pass this barrier over a greater range of flows, allowing access to what is generally considered the most productive habitat in the lower Yuba River.

		The ladder is a major step toward reviving and sustaining one of the last native steelhead trout runs in the South Bay.
		The fish ladder is "essential to the steelhead run," said Patricia Anderson, an area fisheries biologist with the California Department of Fish and Game.
		The fish ladder project consists of a 25-foot "Alaska Steep Pass Fishway" to help adult fish swimming upstream bypass the dam to spawn, as well as a fish screen to prevent adult and juvenile fish from being carried into the Felt Lake diversion on their way downstream.

	The Amoskeag Fishways - About Us
		Anadromous fish are born and grow in the fresh water of rivers and streams, but live as adults in the salt water of oceans.
		Anadromous fish populations began to decline during that time since the fish were unable to pass the dams to reach their traditional spawning grounds.
		This ladder was built as part of an effort to restore anadromous fish populations to the Merrimack River.

	CA DFG News: Nimbus Hatchery Fish Ladder to Open
		Fish and Game personnel take the fish and propagate them artificially, as they have since 1955 when Nimbus and Folsom Dams were constructed and blocked access to historical spawning habitat.
		In addition to watching fish jump up the ladder, visitors are encouraged to take a walk along the River Discovery Trail that extends from the fish ladder downstream for several hundred yards or the hatchery visitor’s center with 20 exhibits on salmon and steelhead trout biology, ecology, management, and conservation.
		Fish will not be spawned on the day the ladder opens as hatchery personnel use the time to make water flow adjustments in the building itself.

	Utility Loses Fish-Ladder Ruling
		If NOAA Fisheries finds fish ladders are more beneficial, FERC has to accept that as a condition of the license.
		Habitat above the dams is good enough, and fish living below the dams are genetically suitable to repopulate the new areas, despite warm water in the summer, diseases in the water, and predators in the reservoirs, the judge found.
		The proposed fish passages would return chinook and endangered coho salmon as well as steelhead and Pacific lamprey to 350 miles of river cut off for more than half a century by the towering hydropower dams.
