| Short Description |
The U.S. Environmental Protection Agency requires states to set priorities for cleaning up 303(d) listed waters and to establish a Total Maximum Daily Load (TMDL) for each. A TMDL entails an analysis of how much of a pollutant load a waterbody can assimilate without violating water quality standards. This Quality Assurance Project Plan describes the technical study that will evaluate temperature, pH, dissolved oxygen, and other ancillary parameters in the Wenatchee River mainstem and Icicle Creek. The TMDL will form the basis for a proposal to set instream water quality targets to meet water quality standards and allocate contaminant loads to sources. For the addendum to this QA Project Plan, see the link below to Related Publications. (Also see abstract below) | |||

| Abstract | Long Description |
The U.S. Environmental Protection Agency (EPA) requires states to set priorities for cleaning up 303(d) listed waters and to establish a Total Maximum Daily Load (TMDL) for each. A TMDL entails an analysis of how much of a pollutant load a waterbody can assimilate without violating water quality standards. This Quality Assurance (QA) Project Plan describes the technical study that will evaluate temperature, pH, dissolved oxygen, and other ancillary parameters in the Wenatchee River mainstem and Icicle Creek. The TMDL will form the basis for a proposal to set instream water quality targets to meet water quality standards and allocate contaminant loads to sources. The study will be conducted by the Ecology Environmental Assessment Program. The Wenatchee River Subbasin (Water Resource Inventory Area, WRIA 45) is located in Chelan County. Watersheds of WRIA 45 are shown in Figure 1. The technical study to address water quality concerns in WRIA 45 will be split into two years. The first study year will focus on the mainstem Wenatchee River from the outlet of Lake Wenatchee to the river's confluence with the Columbia River at the city of Wenatchee, and include Icicle Creek. The second study year will focus on the other major tributaries to the Wenatchee River. This QA Project Plan applies only to year one, an additional QA Project Plan will be developed for year two. |
