To Kate and Dan, Grandpa's pond looks big enough to be a lake-so the fun at the pond is also big and amazing! While following Grandpa's safety rules, Dan, Kate, and their cousins enjoy taking turns paddle boating and kayaking on the pond and riding four-wheelers near the pond. They learn about fly-fishing and homemade flies. They also engage in the wise conservation practice of catching and releasing the fish they are not going to eat. The picnic at the end of the day is full of delicious fish and tasty dishes prepared by their grandparents, parents, aunts, and uncles. With Grandma's help, the children even roast their own s'mores for dessert.

Throughout the day, Kate and Dan are curious about the constantly changing outdoors. They ask their grandfather many questions, and his answers are thoughtful and informative, helping the children learn the value of being good stewards of our natural environment and respecting all life. Our Grandpa Owns a Lake! has educational value and helps readers discover the wonders and customs of various animals, birds, and fish. The book is also entertaining for children, parents, and grandparents, especially when they read it together.

Our Grandpa Owns a Lake! is loosely based on actual experiences that the author and her husband-the grandfather in the book-have had at their Idaho trout pond with their own grandchildren.
