The Current River, a Lake Superior tributary stream, has approximately 50 km of potential spawning and nursery habitat available to rainbow trout. Passage of rainbow trout up this river system, however, was blocked by a dam situated approximately 600 m upstream from the mouth of the river.
Access to productive spawning habitat in the Current River was restored in the fall of 1992 with the construction of a fish ladder and step pools at the Boulevard Lake dam. Additional resting pools were excavated below the fishway to expedite upstream passage. A fish transfer program was initiated in 1993 to accelerate the colonization of rainbow trout in the upper reaches of the Current River. It is anticipated that spawning adults, collected from adjacent streams and transplanted to the headwaters of the Current River, will produce a self-sustaining rainbow trout population over time. |
