Shoreline dock monitor

Know when the water has moved.

See how far the water's edge is estimated to have moved from your dock baseline, and how far to move the dock to follow it.

USACE full-pool reference 1071 ft MSL Reference on the lake-level graph; not used to calculate shoreline movement.

Your shoreline

Set your dock baseline

SETUP

Save the lake's elevation when your dock is positioned correctly at the water's edge. Baseline and current readings must use the same vertical datum. The initial editable 6:1 factor comes from your example; it is not a surveyed shoreline grade. Set alert distances to your safe travel margin: how far the dock can move before its walkway end or float is at risk.

Baseline water level ft elevation Level when the dock was correctly positioned at the water's edge. Edge / lake-level ratio in edge / in lake 6 means 1 in of lake-level change shifts the edge about 6 in. Adjust to your shoreline. Warning dock travel ft movement Alert at this travel distance; the same limit applies in or out. Urgent dock travel ft movement Higher-priority alert; the same limit applies in or out.

My entered baseline uses NAVD88 (required for USGS readings)
