I heard during the Age of Aquarius and under the watchful eye of Posiden the the river became a raging torrent of 97,000,000,000,000 CMS (cubic meters per second, because everyone knows the ancient gods used the metric system). Holy Zeus' beard! that is a lot of water. If it was translated on to the current Pineview gage It would read 680,000m or 2,244,000ft. back then though they were real men, they had flat foreheads and boated in bloated wooly mammoth bladders.
That is the highest known and recorded flow for the poudre river. Pray that the mighty Posiden raises his trident one more time for shits and giggles.
