Minute 319 Pulse Flow Map, 5/1/14

After stalling out for a couple of weeks, the Colorado River Delta Minute 319 pulse flow is back on the move.

According to the latest map and missive from the science team, an earthen dam below the downstream-most habitat restoration site was removed, and the pulse has received an added stimulus from the Kilometer 27 Spillway (see nice NASA map/satellite image for the location). The KM27 release is an aspect of the critical “plumbing” aspect of this environmental restoration experiment. The main river channel, because of dry stretches with low groundwater, is not necessarily the most efficient way to get water to environmental restoration sites in the lower reaches of the delta, so some of the pulse flow water is making part of its journey through CONAGUA irrigation canals.
