There may come a time when we need to resurvey the Lockport to Selkirk area because of significant change, but thus far our testing indicates it is pretty stable. I am sure there are locations wherein a few inches of sediments have been eroded away and in others where deposition has occurred since we surveyed in 2018, but I daresay that those change are so small in magnitude that if we had done a complete resurvey in 2020....the differences would have largely been imperceptible. One thing that really surprised me when we began surveying the Red is that much of the river bed is actually dominated by harder substrates - sediments scoured away down to clay-pack and cobbles. That helps with stability. Its a pretty cool river, both downstream and upstream of Lockport - much more beautiful down below than it looks from shore.
More than likely the Red River mouth area will be the first area that we need to resurvey....lots of potential for change here because it is a depositional environment. Maybe after the next big flood? Or if they end up dredging as has been talked about again recently? Hard to say when touch-up surveying will be required.
