The interactive map displays the selected lake with two overlaid images representing lake depth at different water levels. The left image always shows the lake at full pool (no drawdown), while the right image changes with the selected drawdown level.

Use the drawdown slider to change the water level and compare changes in shoreline, surface area, and depth zones. The map’s zoom and position remain constant for accurate side-by-side comparison.

Drag the vertical comparison slider on the image to reveal differences between full pool and the selected drawdown. The statistics table and chart to the right updates automatically to show habitat and volume metrics for the current depth.
