Some continued decline in livestock consumption is anticipated over the next 20 years.

Any future change in water uses for these sectors could have a large impact on total water use in the county.
Wells supply water for many communities, farms, and industries in east-central Iowa.
The water from these wells comes from deposits of unconsolidated materials and layered rocks whose characteristics are consistent enough to allow fairly reliable predictions as to their location and water-yielding potential. Rocks that store and transmit water are called aquifers. Within east-central Iowa, there are 3 separate surficial aquifers and 5 bedrock aquifers available for use as water supplies. The unconsolidated deposits near the land surface comprise the surficial aquifers. Underlying are layers of sedimentary rock collectively called bedrock.
