Camp water decision result card
What the result means
The water result estimates drinking, cooking, and basic cleanup needs. Heat, pets, hiking, dishwashing, and dry campsites can raise the number.
What to do next
Use the result to choose jugs, bottles, filters, or refill stops before packing food and cooler supplies.
When to round
Round gallons up for hot weather, kids, pets, remote sites, and any trip without reliable refill water.
Real-world examples
Weekend car camp
Inputs: 4 people for 2 days at 1.25 gallons each per day. Result: 10 gallons. Interpretation: two 5-gallon jugs cover basics; next step is food and ice planning.
Hot primitive site
Inputs: 2 adults for 3 days at 2 gallons each per day. Result: 12 gallons. Interpretation: heat and no spigot change the pack list; next step is checking storage space.
Formula or method
Water = people x days x gallons per person per day + reserve.
Pack extra for heat, pets, illness, and cleanup.
