  <dc:description>&lt;p&gt;This report describes and documents a one-dimensional computer model that predicts dissolved-oxygen and temperature profiles in a lake or reservoir. Downstream release dissolved-oxygen concentrations and temperatures also are computed based on a user-specified outflow withdrawal elevation. The model can, therefore, be used to compare top-draw versus bottom-draw outlet configuration effects on downstream dissolved-oxygen and temperature conditions.&lt;/p&gt;&lt;p&gt;The dissolved-oxygen and temperature profiles are computed for a conceptual vertical water column located at the deepest point in the lake or reservoir.. The water column is divided into a series of uniform thickness horizontal layers for computation purposes. The model operates on a daily simulation interval, with summary output given for each day and detailed depth profiles printed on user-specified days. Model options allow the simulation of 5-day biochemical oxygen demand, sediment oxygen demand, and the density current effects of inflowing suspended sediment.&lt;/p&gt;&lt;p&gt;The model is a modification of the U.S. Army Corps of Engineer's "WESTEX" model number 722-F5-E1011. The user-specified withdrawal elevation, dissolved oxygen, biochemical oxygen demand, sediment oxygen demand, and suspended sediment simulation capabilities were not present in the earlier "WESTEX" model. The model is capable of simulating a stratified reservoir pool environment.&lt;/p&gt;&lt;p&gt;This reservoir-lake model is most applicable to preliminary or reconnaissance studies of a proposed impoundment. Other more complex and accurate models exist to model existing lakes or reservoirs where onsite data can be collected.&lt;/p&gt;</dc:description>
