The City of Boulder, Colorado Drought Plan was developed by Hydrosphere, city staff and others to provide a guidance document for recognizing droughts that will affect water supply availability for the city of Boulder and for responding suitably to these droughts.  The plan comprises two volumes:  Volume I is the Drought Response Plan, which includes summary information on Boulder’s water supplies, a categorization of drought levels according to severity, and detailed information on the particular actions that might be taken to respond to each drought alert level. Volume II is the Drought Technical Information and Analysis that provides the supporting documentation for the Drought Response Plan.  The plan reflects extensive input from several public meetings, focus groups, Boulder’s Water Resources Advisory Board and City Council.

The Water Conservation Futures Study was conducted by Hydrosphere and others for the City of Boulder, Colorado to characterize the city's current water use patterns, project future water demands and supplies and provide recommendations for water conservation measures that reduce peak demands to a level that can be handled by current facilities.

The Severe Sustained Drought Study An interdisciplinary investigation of the characteristics and impacts of drought in the arid southwestern portion of the United States, and measures that might be taken to mitigate or respond to those impacts. The study produced thirteen professional papers published in a special edition of the Water Resources Bulletin in October, 1995.
