Framework for Regional, Coordinated Monitoring in the Middle and Upper Deschutes River Basins, Oregon

Ground water redox zonation near La Pine, Oregon: Relation to river position within the aquifer–riparian zone continuum

“…The La Pine study area, as defined in previous investigations by Morgan and others (2007) and others (2005 and2007), encompasses 247 mi 2 of the upper Deschutes Basin in central Oregon ( fig. 1).…”

“…Parts of the Deschutes River do not meet State of Oregon water-quality standards for O 2 and are included in the state 303(d) list of water-quality-impaired streams. Data currently are insufficient to determine the status of O 2 conditions in the Little Deschutes River (Anderson, 2000).…”

Evaluation of Approaches for Managing Nitrate Loading from On-Site Wastewater Systems near La Pine, Oregon

“…Another potential concern is the quality of local streams. The Deschutes and Little Deschutes Rivers, which flow through developed areas near La Pine, have been listed as "water-quality impaired" for temperature and turbidity; nutrient loading from ground water has been identified as a potential contributor to excessive algal growth in some reaches (Anderson, 2000;Jones, 2003) that may exacerbate water-quality concerns.…”

Questions and Answers About the Effects of Septic Systems on Water Quality in the La Pine Area, Oregon

“…Another concern is the quality of local streams (Hinkle, Morgan, and others, 2007). The Deschutes and Little Deschutes Rivers, which flow through the developed areas near La Pine, already have excessive algae in some reaches, possibly due to nutrient (nitrogen and phosphorus) contributions from ground water (Anderson, 2000;Jones, 2003). This map of the area shows the boundary of a USGS study to examine the processes that affect the movement and chemistry of nitrogen in the ground-water system.…”
