Ground-Water Bulletin Series (by county, 1945-1993)

This series of reports describes results of water resource investigations, primarily by county.

Earliest bulletins were primarily basic ground-water data reports and include:

• pumpage, water levels, and water quality
• text, figures, tables, and plate maps
• water well records having geologic descriptions

Later reports (after 1968) became more interpretive.

• maps of data points, bedrock topography, unconsolidated thickness, principal water- bearing units, ground-water availability, and potentiometric surface
• descriptions and cross sections of bedrock, unconsolidated deposits, and principal water-bearing units
• information on potential yield and development potential, aquifer coefficients, water levels, water quality, recharge, and discharge for principal aquifers

See county list below for individual bulletins.

• Water Levels in Indiana
• Water Level Records of Indiana
• Ground-Water Levels in Indiana: 1955 through 1962

Note: For counties not shaded or listed below, no bulletins were completed.
