expected to arrive by noon of that day to further ease pressures on the La Junta <br /> area. <br /> By July 6, Pueblo Reservoir had dropped below the Flood Pool and releases were <br /> below 5,000 cfs. Although Pueblo Dam was out of the official Flood Pool, there was <br /> still approximately 14,000 ac-ft of flood water impounded in the reservoir which <br /> required evacuation. USBR and the CDWR maintained the elevated release rate <br /> from Pueblo Dam for an additional few days before shifted back to normal operations. <br /> By July 11, all flood waters were evacuated from Pueblo Reservoir. <br /> On July 15, the reservoir pool at John Martin Dam peaked at an elevation of 3,850.6 <br /> (325,676 ac-ft), less than 6 inches from the published Flood Pool. Releases from <br /> John Martin were increased from 400 cfs on June 15 to a maximum release of 1,750 <br /> cfs on June 27. John Martin releases remained over 1,000 cfs until mid-August. <br /> Although John Martin never entered flood operations in 2015, it is worth noting that <br /> the reservoir held only 6,157 ac-ft on October 31, 2014, and only 52,767 ac-ft at the <br /> beginning of the 2015 of irrigation season. USACE did not operate for flood control at <br /> Trinidad Reservoir in 2015. <br /> a. Trinidad Lake <br /> The installation of new instrumentation on the Trinidad Dam embankment was <br /> completed during 2015. This instrumentation included eight piezometers and four <br /> inclinometers. Some of these instruments were installed to replace existing <br /> unserviceable units, while other instruments were installed to enhance USACE's <br /> monitoring capabilities along the main dam embankment. The project included the <br /> construction of two permanent access roads along the downstream face of the <br /> embankment. <br /> During 2015, herbicide was applied to woody vegetation as a follow-up treatment to <br /> the vegetation removal and herbicide applications that occurred in 2014. <br /> In FY 2016, gate painting and maintenance will begin on the two service gates and <br /> the two emergency gates in the control tower. The coating treatment reduces <br /> corrosion and increases the service life of the water control structures. <br /> b. John Martin Reservoir <br /> During 2015, several projects were completed on the structure of John Martin Dam. <br /> The installation of four new water stop valves that allow water from the lake to be <br /> used for maintenance issues inside the dam was completed. Two new gate valves <br /> and two new stop check valves were installed on the sump pumps located in the <br /> grouting gallery of the dam. <br /> Lake Hasty, which is situated just downstream of John Martin Dam and to the north <br /> of the Arkansas River channel, is filled by groundwater inflow and reservoir seepage <br /> 3 <br />
