Glen Haven 's location in a narrow valley puts the area at risk for flooding . The Big Thompson Flood of 1976 moved the town hall several feet off its foundation . In September 2013 , approximately 80 percent of Glen Haven 's downtown was destroyed in the 2013 Colorado floods . Access to the town was cut off by the destruction of Larimer County Road 43 on both sides of town ; the section connecting to the town of Drake and US 34 was reopened on December 6 , 2013
