Hydrology, geomorphology and habitat studies of the San Juan River began in 1992 as a part of the San Juan River Basin Recovery Implementation Program (SJRIP). The activities changed from research to monitoring beginning in 1999. Geomorphology monitoring changed in 2005 at the direction of the SJRIP Biology Committee. River cross-section measurement changed from pre- and post-runoff to post-runoff every 5 years with the next measurements in 2009. In 2005, two detailed reach studies were initiated. The reaches were selected and first surveyed in 2005. In 2007, Colorado pikeminnow surveys in the two detailed reaches were added. This report summarizes data collected in 2007 as a part of the long-term monitoring program...

The primary objective of this effort was to investigate the feasibility of constructing 2-6 backwater habitats in the San Juan River between the Animas River confluence and the Hogback Diversion Dam for acclimating stocked young-of-year (YOY) and juvenile Colorado pikeminnow and subsequently increasing their survival and retention within the river. The goal was to identify at least 6 locations where suitable backwaters can be constructed with a total wetted surface area of 1,800 m2 or more (average of 300 m2 per backwater). If backwaters of this size could not be created, then smaller backwaters would be considered. The secondary objective was to increase the abundance of backwater habitat available for use by YOY...

The activities changed from research to monitoring beginning in 1999. The work reported here summarizes data collected in 2001 and 2002 as a part of the longterm monitoring program and compares this data to that collected since 1992.
