" , - ~...,... (jJJj.)lJ 5.0 The Edit Menu Replacement Flow Replacement Flow is water introduced to the river in order to allow an out-of-priority diversion upstream (usually by exchange but also through an augmentation plan or substitute supply plan). If daily records are being kept of the return flow amounts for a transferred water right, that amount should also be recorded in this column. Replacement water can either become Natural Flow, Delivery Flow, or both when it is introduced to the river. Thus, in all situations, an entry in the Replacement column requires corresponding entries in the Natural and/or Delivery column. For example, Union Reservoir water is delivered down the Saint Vrain to the confluence with the South Platte in order to replace depletions associated with the Ground Water Appropriators of the South Platte (GASP) wells. At the confluence a ponion of the replacement water is considered part of the natural stream since it may be divened by the next downstream user with an in-priority water right. The remaining ponion of Union replacement is consid- ered a delivery to points funher downstream. It is imponant to realize that Replacement Flow may only compromise a ponion of the total Natural and Delivery water in the river. In the example above, the Union water is only a ponion of the flow in the Saint Vrain river at its confluence with the South Platte. ~ .. .1, Drvin!! the River The column between the Flow and Diversion columns is the Drying the River indicator. Any structures divening the entire flow of the river should be identified in this column. To identify a structure that dries the river, use the check box in the Priority Diversions dialog (described below). -~ -..;' Diversions The ten columns to the right of the Flow columns reflect diversions from the river for either direct use or storage. The types of diver- sions include In-Priority, Exchange, Transmountain, or Storage Deliveries. Once divened, water may be used directly or stored. Thus, each type of diversion (for example, Priority Diversions) may have entries for both Direct Use and Storage. Diversions of the same type (Priority, for instance) by different water users at the same structure should be identified in the comment column. All values in the Diversion columns, including Storage Diversions, correspond to flow in cfs. Columns under the headings Transmountain and Storage Release accept numeric keyboard input. Use the mouse or arrow keys to change position in the grid, and the number keys to enter information. 21 7/31/94
