The lake location where the Beaver rescued the canoe will be used in the next episode, Wally, the Lifeguard (1960).
The lake is converted to a lake/beach, and if you look closely, you will see the canoe that Beaver rescued.
The last episode to feature Jeri Weil as Judy Hensler.
The lake where Wally and Beaver find the canoe is really the small pond in the northern section of Franklin Canyon Park in Los Angeles, a site frequently used for filming by all the studios because of its close proximity and natural setting.
When Beaver is inspecting his $5 reward for rescuing a man's canoe, he turns it over, giving the camera a clear look. Due to the mid-century practice of not showing real United States currency on film, the bill is a 1915-issue Banco de Sonora (Mexico) 5-peso note (catalog no. P-S1072).
In the newspaper article about Beaver being a hero, his name is misspelled as "Theodour". When Wally shows Beaver the paper, he says "Gee, they spelled my name wrong".
