However, the photography <br />was not done during coordinated reservoir operations. Photography during coordinated reservoir <br />operations and during the peak, if coordinated reservoir operations did not occur on the peak, would be <br />helpful. Ideally, we would like to obtain photography for a variety of flows so that we can determine the <br />affect various peaks have on the habitat and identify any problems associated with the peak flows. <br />Aerial monitoring of the entire Colorado River and tributaries downstream of each participating reservoir <br />during a peak at approximately bank-full conditions would also be very helpful in determining where our <br />"pinch points" are and the potential for flood damages. This photography could be oblique in nature and <br />would not have to be continuous. Hopefully, it could be obtained at minimal added cost at the same time <br />the 15-Mile Reach is flown in the future. Peak flows of the magnitude that occurred in 1997 were very <br />close to, if not greater than, bank-full conditions for many reaches of the river and we hope that some <br />funding can be made available in the future for aerial photography when similar conditions exist. <br />1 <br /> <br />20
