Executive summary of accomplishment (paragraph):  On October 10, 2007 biologists from the Oklahoma Ecological Services Field Office conducted fish surveys at two sites on the Spring River in Oklahoma, with the intent of assessing presence/absence of the federally-threatened Neosho madtom.  The first survey site was located approximately four miles east and one mile north of the town of Quapaw, OK, on the Spring River.  The selection of this sample site was based on a Peoria Tribe of Indians of Oklahoma recent collection of one Neosho madtom at the site, in the summer of 2006.  That specimen is still in possession of the Peoria Tribe and we are continuing to work with the Tribe to ensure the specimen is verified by species experts and cataloged appropriately.  To my knowledge, Neosho madtoms had not been collected in the Spring River in Oklahoma prior to the Tribe’s finding.  During our surveys, available habitat at the site was limited due to recent rain within the watershed.  We sampled two areas within the site, one swift run (Area 1) adjacent to the confluence of an unnamed tributary (W94° 43’ 29.11”, N36° 58’ 11.53”) and one riffle/glide/run complex (Area 2) located adjacent to a gravel bar (W94° 43’ 17.85”, N36° 58’ 15.10”) on the north side of the river (Figure 1).  Habitat at the site was comprised mostly of cobble substrate, with only small amounts of gravel.  Substrate was very compact and difficult to move while kick seining.  Depths sampled ranged from zero to approximately three feet.  We conducted a total of 34 kick seines at the site and no Neosho madtoms were found.  A list of other species sampled is provided below.

Our second survey site was located along a large gravel bar (W94° 43’ 14.28”, N36° 57’ 38.06”) on the Spring River at Bicentennial State Park, located approximately four miles east of Quapaw, OK (Figure 1). Substrate at the site was comprised of mostly loose gravel, with only a small amount of cobble.  We sampled a run/glide/riffle complex adjacent to the gravel bar and immediately downstream where the gravel bar was submerged due to recent rains.  Survey depths ranged from zero to 3 feet.  We conducted a total of 22 seine hauls and captured one Neosho madtom just downstream of the gravel bar in very loose gravel substrate.  The madtom was kept alive until returning to the office where Chris O’meilia and Daniel Fenner took numerous pictures of the specimen for documentation purposes (see picture above).  The specimen was then placed in water, labeled appropriately and frozen in the office’s deep freeze.  We plan to contact various universities to determine if this specimen may contribute to ongoing or future conservation genetics research.  Thanks to all those who participated in this unique find!
