FLORiDA GEOLOGICAL SURVEY


just downstream from the point of diversion would be almost depleted during periods of low flow. This effect will diminish downstream and become almost negligible below Gainer Springs, a group of large artesian springs just downstream from the Washington-Bay County line-. A diversion of 30 mgd is a negligible part of the total flow of 650 mgd into Deer Point Lake and would have no adverse effect on this water supply. A part of the water diverted to the lakes would be merely re-routed through the lakes into the ground and back to the Econfina. Creek through the artesian springs below the dam.
    Deer Point Lake is a fresh-water lake formed November 17, 1961, by a salt-water barrier across North Bay. It covers 4,700 acres and stores about 32,000 acre-feet of water. The lake elevation is 5.0 feet above mean sea level and fluctuates very little.
    Artesian spring water flows from the Floridan aquifer into Econfina Creek directly through the streambed, from the base of rock bluffs and from short runs about a quarter of a mile in length. These springs occur from a point just east of Porter Lake downstream to a point near the Bennett gaging station. Springs contribute about twothirds of the flow of Econfina. Creek.
