05/31/2018 -Fallen cotton wood trees are blocking a portion of the river near the confluence. This location has historically been notorious for obstructions and boaters and recreationists are urged to avoid the area. Signs have been posted at nearby ramps. Due to water flows and the remote location of the obstructions, the Marion County Marine Patrol is unable to mitigate. As water levels drop, they will attempt to remove what they can.
05/17/2018 - Log jam reported between Buell Miller Ramp and Green's Bridge at the upstream end of Wiseman Island. The log jam at the head of the middle Wiseman
Island channel has increased, and the gravel bar upstream of the log jam has
encroached closer to the log jam. The only channel past the log jam is
now less than 20 ‘ wide. Two small logs from the jam extend more than
half way across the channel just under the surface when the river flows are 4.5
at the Mehama river gauge. When the river level drops to summer flows the
location may be impassable to boats; boaters are advised to put in down stream of the obstruction.
The Bureau of Land Management reported two downed trees adjacent to Fisherman's Bend Park on 5/3/18. One tree fell along the north river bank (river right) starting 1.5 miles west of the North 1st Avenue Bridge at Mill City. THIS OBSTRUCTION WAS CLEARED on 5/11/18. The second tree is river right in the main channel at mile 2.3 below the north 1st avenue Bridge at Mill City. The BLM is working on the best plan for mitigating the second obstruction and is coordinating with Marion County. Boaters are advised to put in down stream of the obstruction.
North Santiam (44.685803, -123.004924)- Benton County Marine Patrol cut away a series of trees the best they could for safe passage of jet boats and drift boaters at the confluence of the North and South Santiam Rivers, upstream from Jefferson, OR. This area is notorious for obstructions. Most of the obstruction is river right going upstream, approximately 150 yards upstream from the confluence (pictured below). One of the logs is just below the surface, so jet boaters and prop boats are encouraged to avoid the area due to the strainer and to protect their boats. Sergeant Bottorff says, "Two ways to go
through that stretch of river is to go over the log that is covered by about
6”-1’ of water towards the end of the log, or go to the left and zig zag
past it when heading upstream. Going downstream, the best path is to go over
the log. To go over the log, requires skills to read the
water and jet boat experience." Inexperienced boaters (motor, rafts and drift) should avoid the area and put in downstream of the confluence.
The water has dropped leaving the
log mostly exposed out of the water. There is a passible spot to the left
as described before. This is a dangerous strainer and boaters are advised to use caution.
