Willie takes a field trip; coloring book

This coloring book is an educational tool designed to instruct children on some of the field activities commonly associated with the collection of water resource data. Through the use of line drawings and brief descriptive text, young readers will follow little Willie and his Uncle Bill as they spend a pleasant day in the field measuring streamflow, collecting sediment samples, making groundwater measurements at observation wells, and measuring flow in a pipe. Although this 37-page coloring book is geared to children 5 to 10 years old, people of all ages may find it enjoyable.
