"Springs of the Ocklawaha River from Rodman Dam (River Mile 12) to Eureka Dam (River Mile 33): A Slide Show by Paul Nosca"

32 slide-show views that portray most of the artesian springs or spring runs that are present in and along the Ocklawaha River basin between Rodman Dam (at river mile 12 [RM-12]) and Eureka Dam (at river mile 33 [RM-33]). These photographs were taken since 2007 by Captain Erika Ritter or "Ocklawahaman" Paul Nosca with the great majority of them recorded during 3 different draw-down periods of Rodman Reservoir (a.k.a. Rodman Pool or Lake Ocklawaha).

Shown are: Marion Blue Springs, Catfish Springs, Alcorn Sims Springs, Orange Springs, Indian Bluff Springs, Cracker Landing Springs, Hasty Greene Springs, Big Rack Road Springs, Tobacco Patch Landing Springs, Cannon Springs, Moore Creek Springs, plus 5 other unnamed springs and/or spring runs.

These artesian springs apparently issue forth from the Floridan aquifer in close proximity to the Mount Dora Ridge physiographic subdivision that comprises the southern and eastern high ground upland edge of the Ocklawaha River valley.

Rodman Reservoir's earthen dam was constructed across the historic Ocklawaha River channel at river mile 12 (upstream from the St. Johns River). The concrete and metal Rodman Spillway (with its four 40-foot wide floodgates) is part of that earthen dam. At the usual "full-pool" of Rodman the stage of the water behind Rodman Dam is maintained at 18 to 20 feet above sea level (9,200 to 13,000 surface acres). When Rodman Pool is manipulated to "draw-down" (every 3 to 4 years or so) the stage of the water behind the dam will usually be lowered to a minimum of about 11 feet above sea level (4,300 surface acres). The "crest" of Rodman Spillway plus the upstream "sill" of Buckman Lock -- that the released water flows over -- were built with summits of 6 feet above sea level. Historically the "normal" stage of the natural Ocklawaha River at river mile 12 would have been only about 5 to 6 feet above sea level. Therefore even at a draw-down stage of 11 feet above sea level, the Ocklawaha's artesian springs in Rodman Pool that are closest to Rodman Dam (e.g., Marion Blue Springs and Catfish Springs) are still "drowned" under 5 to 6 feet of backwater.
