On a water boundary, a tie line is used so that the figure can be closed.?ÿ Just wondering how others do it.
Usually there's a monument on each line that heads to the water boundary, many times on the top bank of the river or lake.
I normally run a tie line from monument to monument for closure, and also show a rough distance along the water boundary (even though the fee usually goes to the CL of a river).?ÿ
But I've seen others run many tie lines to various fictitious (calc'ed) points along the water boundary, to form a more or less math'ed approximation of the boundary.?ÿ Is this the normal method for most here?

I owned an interest in a river-side property (Lamoille River, Vermont). It flows into Lake Champlain, which borders on two states and Canada, so is considered US waters. Since there are no obstructions to navigation between the lake and my property, that portion of the river is also considered US waters. Lots of considerations to think about.
Often, the area of the uplands is a question. The reason that a shoreline is meandered in a small lot survey is for much the same reason they did so in the PLSS.
I usually set a monument at top bank and then show a distance rounded to the foot from said monument to my calculated centerline. Tie bearing and distance goes from the calculated points at centerline.
I show courses along the meander line at the date of the field survey. It is for area computation and to compute closure. Offsets are set on line with distances shown too the meander line. It is common practice in the states I’ve worked.
Life has become fiction, with current technology it is possible to measure the waterline at both banks.
Typically whatever you choose to do there will be a note stating that the true boundary is the existing waterline whether it be tidally influence or not and the meanders are only an approximation for the purpose of area computations. I've always preferred that there are two witness corners on line referencing the meander corner. One is lost to erosion, there would still be one remaining farther back. I've had some old tideland surveys where of all the monuments set (two on line) only one monument remained out of all of them, but that one was a whole lot better than none.
