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. <BR> <BR>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. <BR> <BR>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. <BR> <BR>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. <BR> <BR>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. <BR> <BR>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? <BR> <BR>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.
