Legal descriptions were obtained from the 1987 Bureau of Land Management (BLM) St.
George (Utah -Arizona) and Littlefield (Arizona), and 1989 BLM Overton (Nevada -
Arizona) Surface Management Status 30 x 60 Minute Quadrangles. Critical habitat azeas
proposed for the woundfm in each state are as follows:
Wl: Utah, Washington County. The Virgin River from its confluence with Ash-LaVerkin
Creeks in T.41S., R.13W., Sec.23 (Salt Lake Base and Meridian) to the Washington Fields
Diversion in T.42S., R.14W., Sec.21 (Salt Lake Base and Meridian).
W2: Utah, Washington County. The Virgin River from the Washington Fields Diversion in
T.42S., R.14W., Sec.21 (Salt Lake Base and Meridian) to the Johnson Diversion in T.42S.,
R.15W., Sec.27 (Salt Lake Base and Meridian).
W3: Utah, Washington County. The Virgin River from the Johnson Diversion in T.42S.,
R.15W., Sec.27 (Salt Lake Base and Meridian) to the Arizona -Utah border in T.43S.,
R.17W., Sec.36 (Salt Lake Base and Meridian).
W4: Arizona, Mohave County. The Virgin River from the Arizona -Utah border in
T.42N., R.13W., Sec.33 (Salt Lake Base and Meridian) to the Arizona -Nevada border in
T.39N., R.16W., Sec.2 (Salt Lake Base and Meridian).
W5: Nevada, Clazk County. The Virgin River from the Arizona -Nevada border in T.13S.,
R.71E., Sec.15 (Salt Lake Base and Meridian) to the highwater level of Lake Mead in
T.16S., R.68E., Sec.l (Salt Lake Base and Meridian).
Virgin River Chub--The proposed designation for Virgin River chub is on the mainstem
Virgin River and extends from the confluence of Ash-LaVerkin Creeks to just above Lake
Mead. Because of the way the river functions hydrologically the river was divided into five
distinct reaches (Table 1). These reaches total 151.7 km (94.8 mi) as measured along the
center line of each reach. This represents approximately 70.8 percent of the historical
habitat within the Virgin River Basin, excluding the range historically occupied by the
Muddy River population. These reaches flow through both public and private land (Table 2).
