— Despite a strong downpour this weekend, Raleigh's main source of water barely budged.

The lake level was at just 249 feet Monday, only a few inches above Friday's level and still about 2 feet below normal.

Experts say Saturday's rain was not concentrated in the right places to feed the lake.

    Need to plug that big hole that leads to Raleigh...then the lake level will rise.

    "Gee whiz, as the lake rises the amount of surface area it covers increases. So that means it takes more and more gallons of water for each inch that it rises to make it up another inch."

    While that's true, if you look at the streamflow tables of the Eno, Little, and Flat rivers (the main tributaries of Falls Lake), you'll see that the streamflow from the latest rainfall only produced about 1/20th the peak flow from the previous 2 rainfalls.
