shorefront/shoreline beach area question

[Ricky g]

hi folks,

I'm new to the area. I've lurked on the forum a bit to learn what I can about the the towns and lake life. we recently bought a lake house in Meredith. It has an overgrown little beach area, which we were told was grandfathered in to the property. and, if not maintained (meaning cleared/restored) would be lost. At the waterline and into the water for 10-15 ft is all pebbles. the "beach" area is approx. 15'x15'. I pulled the long weeds and raked up the moss. underneath seems to be a layer of more pebbles and it looks like landscape fabric under that.

We are interested in a sand beach if possible. I'm looking for advice/suggestions on how to clean it up; either manually, rent needed equipment or hire it out. I'm not quite sure of the process. what do others do to maintain their beach? would I put sand into the water? about how long till it gets washed away? do I clear all the pebbles first, or go right over with the sand.

maybe not asking in the clearest way, but you get the idea. thanks for and advice or suggestions.
