doonez Posted September 7, 2013 Share Posted September 7, 2013 I Have been seeing the mention of backwash in many threads due to high water and was wondering why the high water makes the backwash so bad? Is it the gradient of the bank changing or the depth of the water? Also how many lakes which are built for skiing have adjustable water levels? The lake we belong to has an vertical outlet so that the water level can be controlled to what suits. Is this common? I know that if its set up high the rollers get unbearable so I really feel for the ballers that put up with this! Thanks Link to comment Share on other sites More sharing options...
Baller A_B Posted September 7, 2013 Baller Share Posted September 7, 2013 Yes it is bank grading. Some lakes have good grade at all levels, others have good banks and then go up steeply at a point past what was considered "normal" level. Link to comment Share on other sites More sharing options...
Baller thager Posted September 7, 2013 Baller Share Posted September 7, 2013 My lake in the spring is bad for backwash. The snow melt brings the water level up to the vertical embankment which reflects waves back out into the lake. As the water recedes and we get some shoreline the waves are dissipated on a natural 12:1 sand slope. No reflection. Sweet!!! Link to comment Share on other sites More sharing options...
