During the past few decades, satellite-derived information has become an integral part of our daily life. Despite many efforts, however, procedures using satellite imagery to measure surface water quality have not been adopted on a routine basis. This article reports on the authors' attempts to develop workable procedures for routine use of satellite imagery and related technology to assess surface water-quality conditions by Minnesota's water management agencies, and provides some perspectives on the likely future role of satellite- and aircraft-based remote sensing techniques in water resource monitoring and management in Minnesota.
