They attempted to study the effect of ballast on weight height on a Moomba LVX. However there were so many other boats in the area they couldn't conclude any meaningful results.
The claim that fish habitat is effected by boat wakes can only be possible in bodies of water that are too shallow for serious wakeboarding. If the fish spawn below 5 feet the prop wash should have little effect. If the fish spawn in water shallower than 5 feet there could be issues. However, I rarely boat in waters so shallow.
I assume that the property owners are attributing erosion to only one force, wakeboard boats. Natural hydraulic effects of an active river dwarf the effect of a boat wake. Not knowing how wind effects the water way, if the river is in a valley or not, I can’t conclude what the effects of wind driven waves on the shoreline might be.
If the property owner with the wash out is on the out side of a natural bend in the river then erosion by the river is a very natural and powerful effect and fact of life.
How has urban development progresses in the Willamett River area? Has there been a lot of development? How much of the surrounding land has been sealed. By sealed I mean how much area is covered by roof tops, driveways, roads, parking lots, and large industrial buildings? Sealing off the ground can drastically increase flow rates and increase flooding.
Wakeboarding is very visual and something you go notice on a nice day. No one is watching what’s going on a lousy raining day. What are rain flal and flooding records like in the area?
My lake is several miles long and is 300 to 600 feet wide. The narrowness of this body of water and the fact that it’s in a valley make it one of the best lakes I’ve been on. It’s also a great body of water for sculling. The rowers want to claim the lake for themselves and have big Ohio State Athletics funds behind them.
