The recent weather combined with seasonal run-off provides a good opportunity to remind residents about the dangers of flooding and the importance of being prepared. Water levels and flow rates in creeks and ditches can fluctuate from day to day. Residents are asked to be aware of conditions and to be especially cautious with children and pets near these waterways. High, fast-flowing water can lead to dangerous situations in a matter of moments.
In the interest of public safety, the Town of Lyons has enacted a tubing and single chamber flotation device ban on the Saint Vrain Creeks due to dangerously high runoff and storm flows. The ban will be in effect until further notice.
