Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
Runoff from agricultural lands into Upper Klamath Basin rivers and lakes can
cause water quality problems affecting fish and wildlife. Excessive eutrophication
in Upper Klamath Lake is linked to high nutrient input (particularly phosphorus)
stemming from both lake sediments and watershed tributaries.
On a unit area load basis the Wood...
Water quality problems related to excessive algal
growth, high nutrient loading, and low flows have been
occurring along Oregon's Tualatin River. The Tualatin River
is 86 miles long and has a drainage basin of 711 square
miles. The drainage basin incorporates forest,
agricultural, and urban areas. Located in the Portland...
The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...
