There was limited inflow <br />from snowmeh in March, continuing through April. With slightly below average snowpack and <br />minor spring precipitation, all ponds paniallyfilled during April and May. Most of the ponds retained <br />some water through October, except for the ponds associated with Stations 303 and 321, which were <br />dry by the end of July. The only outflow during the 2003 water year was minor discharge az Stazion <br />305 during May and negligible spillage to several discharge structures due to wave anion in late May. <br />Surface water sites 300, 306, 322, and 327 were dropped from monitoring as of January 1999 and site <br />314 was eliminazed from the monitoring program in October 1999. No daza was collected from any <br />of these sites during the 2003 water year. <br />• <br />~I <br />MWH * 1475 Pve GroreRd, Ste 109, * Staxr~lmt Spivgs, Cdarado 80477 * (970) 879-6260 Reu 11/04 <br />IR.\WPVr.Qd18s)unYdfxyboRyu\xMJ1xP11 XyM~Rgoe <br />3/19NC.6 <br />
