Afloat On The Flood by Lawrence J. Leslie

Excerpt:
"What's the latest weather report down at the post office, Max?"
"More rain coming, they say, and everybody is as gloomy as a funeral."
"My stars! the poor old town of Carson is getting a heavy dose this spring, for a fact; nothing but rain, rain, and then some more rain."
"Never was anything to beat it, Bandy-legs, and they say even the oldest inhabitant can't remember when the Evergreen River was at a higher stage than it is right now."
