Army Corps Proposes to Close Section of North Santiam River (OR) for Two Years
The Army Corps of Engineers has just released a Draft Environmental Assessment to rebuild the
Minto Fish Collection Facility on the North Santiam River. The purpose of the facility and the
associated dam is to collect fish before they continue upstream and hit the artificial barrier
created by Big Cliff Dam. Most boaters know this facility as the place with the hazardous low
head dam between Niagara County Park and Packsaddle County Park on the river.
As part of the project the Army Corps of Engineers proposes to build a formal trail suitable for
kayaks to portage the dam--unfortunately the dam itself would not be rebuilt as part of this
project and would remain as a safety hazard. Of additional concern to paddlers, this section of
the river would be closed for two years during construction of the new fish collection facility.
The Army Corps of Engineers is currently soliciting public feedback on their proposal through
September 4, 2010. Several members have contacted us about this project and American Whitewater
anticipates providing comments. We suggest that those who enjoy this river do so as well.
Paddlers can submit comments on the proposal which can be reviewed on the Army Corps of Engineers
website

Relevant sections of the Environmental Assessment that relate to the interests of whitewater
paddlers include the following:
Barrier Dam, 2.2.5, Page 16
There are no plans to modify the existing dam as part of the project. Members of the paddling
community have expressed an interest in safety improvements to this structure possibly including
a boat chute. The EA states:
"It was decided not to make major modifications to the barrier dam in order to minimize
impacts on current hydraulic conditions immediately downstream of the barrier. The NMFS exclusion
barrier criteria call for either a velocity barrier or a vertical drop structure. The current
barrier dam does not meet either criteria. It currently uses a combination of velocity and
vertical drop (approximately 10 feet from forebay to tailrace for most flows) to prevent fish
from passing. However, the barrier dam performs as an adequate barrier for the facility’s
design range of 895 to 5,370 cfs river flows; when flows exceed 5,370 cfs, the barrier dam does
not completely exclude fish passage along the south shore."
Kayak Landing and Portage, 2.2.8, page 17
The Army Corps of Engineers proposes building a portage trail for kayaks that would begin 400
feet upstream of the dam. The EA states:
"A kayak take-out landing, portage trail, and put-in will be constructed to facilitate safe
kayak portage around the barrier dam. The take-out will be located on the north shore of the
North Santiam River approximately 400 feet upstream of the barrier dam. The take-out will consist
of a cleared area along the bank and the installation of a steel staircase connecting the trail
to the water. The portage Minto Fish Collection Facility Rebuild Environmental Assessment will
traverse the perimeter of the project along the outside of the security fencing from the take out
to the railroad grade and then follow the fencing back down to the river downstream from the
facility with a steel staircase descending the final steep portion of the hillside to the put-in
landing on the river."
Recreation 3.7.2, page 36
"The analysis on recreational use references kayaks but does not consider rafts. The EA
states:
The North Santiam River is popular for recreational fishing and boating. Currently, boating
activity on the river above the barrier dam at Minto is limited to small personal watercraft such
as kayaks. Most frequently, larger boats are launched at Packsaddle Park, which is below the
Minto barrier dam. Smaller boats, particularly kayaks, launch at Niagara County Park or above and
take out at Packsaddle Park, typically portaging around the barrier dam by walking through the
existing fish facility. Some bank fishing occurs above the barrier dam where access is available.
Most of the lands adjacent to the North Santiam River between the Minto facility and Big Cliff
Dam are in private ownership, however some public access is available at Niagara County Park and
where the North Santiam Highway runs adjacent to the river."
Recreation 4.7.2, page 43
The Army Corps of Engineers proposes a two year closure of the river from Niagara County Park to
Packsaddle County Park with construction of a portage trail for kayaks to take place during that
period. The EA States:
"The proposed action would have a temporary, adverse impact to recreational boaters that
currently use the North Santiam River upstream from the Minto site. The North Santiam River will
be closed to navigation from Niagara County Park to Packsaddle during the 2-year construction
window. The proposed closure is being coordinated with the Oregon State Marine Board. However,
rebuilding the Minto facility is expected to have a long-term, positive impact on recreational
vessel safety once new signage is installed and the take-out above the facility and put-in below
the facility are improved. Bank fishing will be unaffected by the construction activities."
