Dry Stretch Water Carry Capacity Planner
Do the carry arithmetic without pretending there is one correct hydration rate. Enter your own observed consumption, expected moving time, planned reserve and container capacity, then compare what you intend to carry with the number you entered.
Not hydration or route advice. This tool does not tell you how much you should drink and does not verify water sources. Heat, exertion, illness, altitude and individual needs can change water requirements substantially. Source reports can be stale; verify current route conditions from reliable local sources.
Example mode. Your saved plans are untouched.

Why this tool asks for your own observed rate
A planning calculator can multiply distance, speed and a number you provide. It cannot know your body, weather, illness risk, heat exposure or route conditions well enough to prescribe a universal water intake. Keeping the rate user-entered makes the calculation explicit instead of hiding a medical assumption inside the tool.
