Travel time from the Keystone gage to North Platte is estimated to be 2 days. This <br />estimate is based on discussions with CNPPID and is supported by empirical <br />evidence in the stream gage data. Similarly, the travel time from the Roscoe gage on <br />the South Platte to the gage at North Platte is estimated to be 2 days based on stream <br />gage data. Travel time from North Platte (the confluence) to Brady on the Platte River <br />is estimated to be about 1 day. The actual travel time may be shorter than 1 day; <br />however, the 1 day timestep and the proximity of the Jeffrey Return to Brady support <br />this approximation. The next downstream reach terminates at the J-2 Return and the <br />Overton gage. These two locations are also grouped based on their proximity to each <br />other. The travel time for this reach is estimated to be 1 day. The total travel time <br />from Lake McConaughy/Roscoe downstream to Overton is thus approximated to be 4 <br />days. Table 3-5 entitled "Travel Times on the Platte River - Keystone to Overton", <br />summarizes the travel times incorporated in this study. <br />Table 3-5 <br />Travel Times on the Platte River - Keystone to Overton <br />Reach Upstream Downstream Approx.
