Every spring, the Cache la Poudre River rises as mountain snows melt. Some years there is abundant snow and the river’s flow is high enough to clean and refresh the river. Other years we have a dry winter and, because there are lots of diversions, there may be hardly any water left in the river in Fort Collins and the river suffers. Regardless, every year at some point the river hits its “peak” snowmelt-driven flow, when the water is at its highest, usually in June — thus “June Rise” — but ranging from about May 15th through June. After that, water levels drop.
What will the river do in 2009? You be the judge in Save The Poudre’s First Annual June Rise Contest. Guess when the Poudre River runoff will peak at the USGS Canyon Mouth Gage, as well as how much the actual peak flow will be in cubic feet per second (cfs).
