[1.] These indicators were updated to 2016-May-15.  All other values are as of 2016-Apr-30.
[2.] While the 30 day average streamflows had not yet recovered at the time of this evaluation, the higher daily flows since the start of the month and the response to more recent rainfall make it clear that at least three of the stream gages in this region, and probably all four, will be within the normal range when evaluated at the end of the month. Since the rainfall and reservoir indicators are also expected to be be normal at the end of the month, the drought status is also expected to be normal when evaluated at the end of the month. While the US Drought Monitor for 2016-May-17 still indicates a moderate drought within part of the area, we do not believe that a drought watch is warranted at this time.

[1.]Because of the rainfall that had already occurred at the time this evaluation was completed, and the predicted rainfall at that time, it was decided to defer any drought declaration until a mid-month assessment could be made.

Normal[1.] - Although two indicators are in drought Watch, recent precipitation and stream flow responce indicate that a drought Watch declaration would not be appropriate at this time.

[1.] Although there are two indicators in the Watch status for the Western Region, the overall status is considered Normal because:

  1. According to the US Drought Monitor. conditions have improved between 3/3/2015 and 3/10/2015.
  2. There was only one stream gage with reliable data available, making our evaluation limited.
  3. Any declaration of drought Watch during a sseason when there is no outdoor water use would have no real impact.

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.
