Water Year 2014 was a “Critically Dry” water year type as classified by the California Department of Water Resources (DWR). Typical for a Critically Dry Year, 369,000 acre feet of Trinity River water were allocated for restoration releases. The peak flow bench reached a magnitude of 1,500 cfs. Continuous turbidity records were collected at three of the four sites (none at TRAL due to the very low turbidity which occurs in the short distance downstream of the dam). Additionally, continuous streamflow was calculated for the TRGV site. This is the one site where a USGS gage is not co-located with the sediment monitoring sites. Maximum observed turbidity (upstream to downstream) occurred as follows: • TRGV 10.6 FNU • TRLG 12.9 FNU • TRDC 21.9 FNU At each site, as in other years, turbidity peaked with the rise to the peak in discharge, then quickly dropped as the flow release progressed.
