[2]Because we are in the growing season and the lack of improvement in the ground water indicator, and because these regions had been in Watch when last evaluated in April, the Administration has decided to continue the drought watch in these two regions.
[3]Pending more information, given the previous status of the region and considering the resistance to drought possessed by water supplies in the Southern region, this region's overall status is being held at Normal.

In order to monitor drought conditions across the State, Maryland Department of the Environment performs and monthly evaluations of hydrologic indicators. These indicators are precipitation, stream flow, ground water levels and reservoir storage. These indicators are used in conjunction with the condition of water supplies, status of utilities, temperature, season of year and other relevant factors. This method was endorsed by the Water Conservation/Drought Task Force Committee to measure the impact of a drought on a regional basis throughout the State.

Drought conditions are evaluated on a regional basis. Precipitation, however, is also reviewed statewide and by county. The task force plan allows for staged response to drought, with conditions being in the "Normal," "Watch," "Warning," or "Emergency." In order for a region to be placed in the "Watch," "Warning," or "Emergency" stage, two or more indicators must be in that category or a higher level.
