Drought conditions in Maine, 1999-2002: A historical perspective
Pamela J. Lombard
2004, Water-Resources Investigations Report 2003-4310
Hydrologic drought can be defined as reduced streamflow, declining ground-water levels, and (or) reductions in lake or reservoir levels. Monthly precipitation totals, annual 7-day low-flow surface-water recurrence intervals, and month-end ground-water levels from drought years 1999-2002 show that 1999-2002 was the driest period of hydrologic drought in more than 50...
