INTRODUCTION
The Interagency Standardized Monitoring Program (ISMP) began in 1986 during the
coordination process that ultimately resulted in the Recovery Program for the Endangered
Fishes of the Upper Colorado River Basil ISMP targeted species and reaches where
considerable information was already available. As originally designed, ISMP targeted
young-of--year (YOY) Colorado squawfish Prychocheilus lucius, subadult and adult Colorado
squawfish, and adult humpback chub Gila cypha. However, information on other rare or
introduced species was collected when they were encountered.
ISMP used existing data (e.g., Wick et al. 1981, 1985a, 1985b, 1986; Tyus et al. 1982,
1987; Valdez et al. 1982; Archer et al. 1985) to identify river reaches that were important to
different life stages of the endangered fishes. The program then developed specific sampling
strategies that could be repeated every year to provide an index of relative abundance for
these life stages. Over the life of ISMP, trends in relative abundance among years and rivers .
will be used in conjunction with data collected with other studies to evaluate the success of
the Upper Basin Recovery Program.
Data collected during ISMP have been presented in a variety of reports, usually
delineated by regional or state boundaries or by species and life history category. An annual
summary was produced during early ISMP (USFWS et.al 1987-1991). McAda and Kaeding
(1989), Osmundson and Kaeding (1991), Valdez and Cowdell (1992, 1993, 1994, 1996), and
Valdez et al. (1995) summarized various portions of the YOY Colorado squawfish data
relative to variation in reproductive success or over-winter survival. In Utah, Bates et al.
(1993) presented YOY and subadult-adult Colorado squawfish monitoring data for the lower
Green and Colorado rivers through 1990, and Cranney (1990) did the same for the lower
White and upper Green rivers. Nesler (1992) summarized the same data for the upper
Colorado, upper White, and Yampa rivers in Colorado. More recently, Day (1995)
presented the 1990-1994 ISMP data from the upper Green and lower White rivers and Day
and Crosby (1996) summarized 1995 ISMP data from the upper Green and lower White
rivers. McAda (1993) summarized the 1989-1991 YOY Colorado squawfish data in relation
to backwater number and surface area as measured by aerial video. McAda et al. (1994a)
summarized all data collected during ISMP from 1986 through 1992. Annual reports were
prepared for data collected during 1993, 1994, and 1995 (McAda et al. 1994b, 1995, 1996).
