Rains eased worst of Maryland drought

The weekly Drought Monitor map is in, and it shows dramatic improvement from the previous week, thanks to five days of rain last week. But the drought persists across more than a third of the state.

Last week's rains erased all traces of "extreme" drought from the state's map. It had climbed to 66 percent by the 23rd, which was the day the rains started falling here.

The portion of the state still rated in "severe" drought, according to the U.S. Dept. of Agriculture fell this week from 87 percent to just 35 percent. Most of that is concentrated in Southern Maryland and the southern half of the Eastern Shore. There's also a pocket of severe drought persisting in southern Frederick, western Montgomery and western Howard counties.

Eighty-four percent of the state continues to experience abnormally dry conditions, or worse, however. Only 15 percent enjoys normal moisture, up from 6.8 percent last week.

These ratings are based on a combination of factors, including soil moisture, stream flow, rainfall and satellite assessments of vegetation health.

In the meantime, the USGS reports stream flow across the state has improved, but many continue to be well below normal levels for this time of year. And ground water recovery has been uneven. This Baltimore County well clearly got a bump from last week's rains, but has quickly resumed its downward slippage since.

We still need more rain. The months of November through April are when the reservoirs and groundwater resources need to recharge. Evaporation is down, consumption is down and plant life isn't using as much water, so more flows into our reserves. But it still needs to fall from the sky first to be of any benefit.

The next opportunity for some rain? Sorry. None in the forecast. And Tropical Storm Noel is headed out to sea.

In the meantime, the feds have just launched a new Web site that brings together a wealth of information and data about the ongoing drought here and in other parts of the country. Here's the link.
