Virgin Spinedace--The Service is proposing sixteen reaches within the Virgin River Basin as
critical habitat for the Virgin spinedace (Table 1). These reaches total 201.9 km (126.2 mi)
as measured along the center line of each reach. This represents approximately 87.7 percent
of the historical 230.2 km (143.9 mi) (Valdez et al. 1991) of habitat for this species.
Critical habitat is being proposed in the mainstem Virgin River, the East and North Forks of
the Virgin River, Beaver Dam Wash, Shunes Creek, Moody Wash, Mogatsu Creek, the
Santa Clara River, Ash Creek, La Verkin Creek, aad North Creek. These reaches flow
through both public and private land (Table 2).
Legal descriptions were obtained from the 1987 BLM St. George (Utah -Arizona) and
Littlefield (Arizona), and 1983 BLM Kanab (Utah -Arizona) Surface Management Status 30
x60 Minute Quadrangles. Critical habitat areas proposed for the Virgin spinedace in each
state are as follows:
VSl: Arizona, Mohave County. Beaver Dam Wash from the confluence with the Virgin
River in T.40N., R.15W., Sec.4 (Salt Lake Base and Meridian) upstream 1.3 km (0.8 mi} in
T.40N., R15W., Sec.S (Salt Lake Base and Meridian).
VS2: Utah, Kane County. The East Fork of the Virgin River from the falls in Parunuweap
Canyon in T.425. , R.9W . , Sec.S (Salt Lake Base and Meridian) to its confluence with the
North Fork of the Virgin River in T.42S., R.lOW., Sec.S (Salt Lake Base and Meridian).
VS3: Utah, Kane County. Shunes Creek from the Second Creek confluence in T.425.,
R.lOW., Sec.ll (Salt Lake Base and Meridian) to its confluence with the East Fork of the
Virgin River in T.42S., R.lOW., Sec.4 (Salt Lake Base and Meridian).
