Agency
Fish and Wildlife Service, Interior.
Action
Proposed rule; notice of reopening of the comment period.
-----------------------------------------------------------------------
Summary
The Fish and Wildlife Service (Service) provides notice that the comment period is reopened on the proposal to designate critical habitat for woundfin (Plagopterus argentissimus) and Virgin River chub (Gila seminuda = G. robusta seminuda), two species of fish federally listed as endangered pursuant to the Endangered Species Act (Act), and for Virgin spinedace (Lepidomeda mollispinis mollispinis), a species proposed for listing as threatened under the Act. All three species of fish are endemic to the Virgin River Basin of southwestern Utah, northwestern Arizona, and southeastern Nevada. Comments received during the entire comment period, April 5 to June 20, 1995, will be considered before finalizing the designation of critical habitat.
Dates
The comment period, which originally closed on June 5, 1995, will now close on June 20, 1995. The comment period has been extended due to several requests from the public.
Addresses
Written comments and materials concerning this proposal should be sent to the Field Supervisor, U.S. Fish and Wildlife Service, Salt Lake City Field Office, 145 East 1300 South, Suite 404, Lincoln Plaza, Salt Lake City, Utah 84115.

Supplementary Information
Background
The woundfin, Virgin River chub and Virgin spinedace are endemic to the Virgin River Basin. The Virgin River originates in south-central Utah, running in a southwest direction from Utah, to northwestern Arizona, and southeastern Nevada for approximately 320 kilometers (km) (200 miles (mi)) before emptying into Lake Mead. The Virgin River populations of these fishes have declined due to the cumulative effects of environmental impacts that resulted in habitat loss including: Dewatering from numerous diversions, proliferation of nonactive fishes, alterations to natural flow, temperature, and sediment regimes. There is considerable overlap in critical habitat proposed for the three species, and the proposed designation includes 330.8 km (206.8 mi) of the Virgin River in portions of Utah, Arizona, and Nevada. The Service proposes 151.7 km (94.8 mi) of critical habitat for the woundfin (approximately 13.5 percent of its historical range); 151.7 km (94.8 mi) for the Virgin River chub (70.8 percent of its historical range, excluding the range historically occupied by the Muddy River form); and 201.9 km (126.2 mi) for the Virgin spinedace (87.3 percent of its historical range). The proposed rule to designate critical habitat for the three fishes was published on April 5, 1995 (60 FR 17296). A public hearing was held on
May 8, 1995, in St. George, Utah. No further public hearings will be held.
