City of Boulder Water Supply and Climate Change Planning

Lynker staff have supported the City of Boulder’s water supply planning efforts since the 1990’s with the implementation of CRAM to model their raw water supply system. Since 2003, the City of Boulder has incorporated climate change assessment into its water supply planning model, most recently in a NOAA-sponsored study initiated in 2006 and completed in 2008. Lynker staff completed model runs with climate-adjusted model forcings (climate adjusted natural flow and irrigation demands) to analyze system performance under future hydrologic conditions. In 2016, Lynker extended the CRAM modeling period of record to 2016 to include the 2012 drought conditions and updated the climate change analysis to include the Colorado River Water Availability Study Phase II climate adjustments to hydrology for the Boulder Creek watershed.
