River Conditions Comparison Tool

This tool can be used by community members and designers to compare river conditions related to people, water, and the environment side by side in river ruler format.

Drag a title from the left side of the screen onto the grid to the right to add a ruler. Drag rulers on the right to reorder them. And drag rulers from the right side of the screen to the left to remove them.

As you mouse over the rulers, a line with the current river mile will follow your cursor. Double click to make one of the lines stay. Single click to remove one.
