Water resources of northeast Iowa

In 1965 a cooperative investigation with the U.S. Geological Survey produced Water Atlas No. 1 (Twenter and Coble, 1965).  It presented information on the occurrence, availability, use, quality, and future demand of water in 10 counties in the central part of the state.  Subsequent investigations produced Water Atlases No. 4 (Coble and Roberts, 1971) for southeast Iowa, No. 5 (Cagle and Heinitz, 1978) for south-central Iowa, No. 6 (Wahl et al., 1978) for east-central Iowa, and No. 7 (Buchmiller et al., 1985) for north-central Iowa.  The present study, Water Atlas No. 8 (1989), describes the surface-water and groundwater resources of 11 counties in extreme northeast Iowa.  With the publication of this report, water atlases are now available for the eastern two-thirds of the state.
