Synthesis of Upper Verde River research and monitoring 1993-2008

Abstract

This volume is a state-of-knowledge synthesis of monitoring and research conducted on the Upper Verde River (UVR) of Arizona. It contains information on the history, hydrology, soils, geomorphology, vegetation, and fish fauna of the area that can help land managers and other scientists in successfully conducting ecosystem management and future monitoring and research in this important Southwest river ecosystem. Chapter 1 provides an introduction to the UVR's location, vegetation, climate, soils, and watersheds. A historical and pictorial perspective of the UVR is presented in Chapter 2. The hydrology of the watershed and its current physical condition are covered in Chapters 3 and 4. Geomorphic relationships of the UVR channels are described in Chapter 5. The woody and herbaceous vegetation of the UVR are presented in Chapters 6 and 7. Water quality status and issues of the river are discussed in Chapter 8. The status of the fish fauna and other aquatic organisms are described in Chapter 9. Chapters 10 through 12 present summaries of information resources, research recommendations, a summary of this volume, and conclusions.

Increasing drought favors nonnative fishes in a dryland river: evidence from a multispecies demographic model

“…; Neary et al. ). River discharge representative of our study area has been measured in the mainstem upper Verde River continuously since 1963 (USGS gage 09503700).…”

“…Spring medium‐flood events, corresponded roughly to bankfull flows, had a maximum discharge that exceeded 6.2 m 3 /s, with a 2.5‐yr recurrence interval in the spring (Phillips and Ingersoll , Neary et al. ). Summer (and monsoon season) high‐flow events (1 May–30 September) exceeded a maximum discharge of 5.7 m 3 /s, representing a 4‐yr recurrence interval in the summer.…”

“…, Neary et al. ). Data from 2002 were omitted from the analysis because only two of seven long‐term sites were surveyed.…”

“…By contrast, numerous nonnative fishes are present in the Verde system, including several species of centrarchids, ictalurid catfishes, and minnows (Rinne 2005). The Verde River has been the focus of detailed monitoring efforts starting in the 1990s, where fish community composition in relation to flow and habitat requirements have been examined annually for the period 1994-2008 (Stefferud and Rinne 1995, Rinne and Miller 2006, Neary et al 2012). These surveys included seven sites in the upper Verde River, encompassing a spatial extent of approximately 60 river kilometers and representing all valley types and habitats occurring within the Verde River ( Fig.…”

Riparian trees and aridland streams of the southwestern United States: An assessment of the past, present, and future

“…With their high elevation (>3000 m) and latitudinal position, the Rocky Mountains accumulate considerable snowpack during the winter months, which contributes to high flows in the spring and summer. The Central Highland ranges are lower in elevation and latitude than the Rocky Mountains, so snowmelt, rain, or a combination of the two can produce high flows (Webb et al, 2007;Neary et al, 2012). The Central Highlands intercept extremely large amounts of rainfall from Pacific frontal storms in winter, tropical storms in the fall, and monsoon storms in the summer SerratCapdevila et al, 2013).…”
