Magnetotelluric Data, San Luis Valley, Colorado
Brian D. Rodriguez, Jackie M. Williams
2008, Open-File Report 2007-1405
The San Luis Valley region population is growing. Water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region?s ground-water resources. An important issue in managing the ground-water resources is a better understanding of the hydrogeology of the...
Assessing the feasibility of native fish reintroductions: a framework and example applied to bull trout in the Clackamas River, Oregon
Jason B. Dunham, Kirsten Gallo
2008, Open-File Report 2008-1007
In a species conservation context, translocations can be an important tool, but they frequently fail to successfully establish new populations. We consider the case of reintroductions for bull trout (Salvelinus confluentus), a federally-listed threatened species with a widespread but declining distribution in western North America. Our specific objectives in this...
Techniques for Monitoring Razorback Sucker in the Lower Colorado River, Hoover to Parker Dams, 2006-2007, Final Report
Gordon A. Mueller, Richard Wydoski, Eric Best, Steve Hiebert, Jeff Lantow, Mark Santee, Bill Goettlicher, Joe Millosovich
2008, Open-File Report 2008-1245
Trammel netting is generally the accepted method of monitoring razorback sucker in reservoirs, but this method is ineffective for monitoring this fish in rivers. Trammel nets set in the current become fouled with debris, and nets set in backwaters capture high numbers of nontarget species. Nontargeted fish composed 97 percent...
