Available in PDF, EPUB and Kindle. Book excerpt: This is a print-on-demand edition of a hard-to-find report.Production of high-quality water is a vitally important ecosystem service in the interior Columbia River basin (ICRB), and there is concern about the maintenance of this water supply for domestic, agricultural, industrial, recreational, and ecosystem uses. Water quantity and quality are an important component of habitat for depleted salmonid populations in the ICRB where a multi-agency effort is underway to restore salmon, trout, and char listed as threatened or endangered. An active program of salmonid restoration is ongoing in the Entiat River sub-basin, During spring 2007, the authors began testing a pilot water quality monitoring strategy using multi-parameter data-logging instruments.

Book excerpt: Production of high-quality water is a vitally important ecosystem service in the largely semiarid interior Columbia River basin (ICRB). Communities, tribal governments, and various agencies are concerned about maintenance of this water supply for domestic, agricultural, industrial, recreational, and ecosystem uses. Water quantity and quality are widely recognized as important components of habitat for depleted salmonid populations in the ICRB where a large, multiagency effort is underway to restore salmon, trout, and char listed as threatened or endangered under the federal Endangered Species Act. A particularly active program of salmonid restoration is ongoing in the Entiat River subbasin, part of the ICRB that drains a portion of the eastern slope of the Cascade Mountains in central Washington state. In the Entiat River, monitoring of compliance with the 1977 federal Clean Water Act has identified water temperature and especially pH as water quality parameters of concern. For these reasons, agencies and others concerned with production of high-quality water and restoration of listed salmonids require meaningful and efficient approaches to water quality monitoring.

Book excerpt: The Integrated Status and Effectiveness Monitoring Project (ISEMP) program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductance and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the late spring 2007, PNW deployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. Data collection was seasonally interrupted by river ice in early December. Daily average pH did not exceed the water quality standard of 8.5 at any of the measurements sites. However, instantaneous values did exceed this standard near the mouth of the Entiat River during late summer-fall period. This suggested that in the lowest portion of the river peaks in pH may be occurring because of photosynthesis caused by high rates of periphyton productivity in response to increased sunlight, temperature, and possible nutrient enrichment. Conversely, dissolved oxygen reached annual low levels during this same late summer-fall period, in part because of increased water temperatures and increased biochemical oxygen demand.

Book excerpt: Excerpt from Water Quality Trends in the Entiat River Watershed: 2007-2010 The focus on salmonid restoration and concern over Clean Water Act listings make water quality a matter of particular interest to the Entiat Watershed Planning Unit (ewpu), tribes, agencies, and other interested parties (cccd 2004; ncaa Fisheries 2012; wdoe 2008, The. Study reported herein is largely a response to discussions among ewpu members in 2005 and 2006 regarding the need for additional information on river ph in the watershed. Primary objectives include defining the spatial and temporal extent of high ph conditions and identifying sections of river that may contribute high ph water. The scope is broad scale and exploratory in nature, although findings may lead to more focused and detailed investigations. Results for the years 2007 through 2008 were reported in Bookter et al. The present report includes results for the years 2007 through 2010. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: A large, multiagency effort is underway in the interior Columbia River basin (ICRB) to restore salmon, trout, and char listed as threatened or endangered under the 1973 federal Endangered Species Act. Water quantity and quality are widely recognized as important components of habitat for these depleted salmonid populations. There is also broad concern about maintaining a high-quality water supply for other societal and ecosystem uses. A particularly active salmonid habitat restoration program is being conducted in the Entiat River, which drains a portion of the eastern slope of the Cascade Mountains in central Washington state. There, routine monitoring by the Washington Department of Ecology identifies pH and water temperature as water quality parameters of concern. In response, the U.S. Forest Service, Pacific Northwest Research Station is testing a more intensive approach to water quality monitoring that uses multiparameter data-logging instruments at four locations to measure fundamental water quality parameters (pH, water temperature, dissolved oxygen, and specific conductivity). This report presents results from the first 4 years of the study and discusses variation in water quality parameters with season, river discharge, and location. We demonstrate that unattended data-logging instruments effectively provide high-resolution data, which facilitate identification of forcing mechanisms such as direct solar radiation, air temperature, and river discharge. Results complement ongoing, broad-scale salmon recovery monitoring by quantifying concurrent changes in water quality. Although exploratory in nature, this study can inform future, more intensive monitoring programs.
