Provisional Data for October 2001 INDEX OBSERVATION WELLS The observation-well network generally reflects conditions in water-table sand and gravel aquifers and does not necessarily reflect conditions in confined and bedrock aquifers. Water levels in N1259, N1616, Q1249, Sa-1100, S1806, and S1810 have been affected by changes in ground-water withdrawals or sewering.
