There was limited inflow from snowmelt in Mazch, <br />continuing through April. With slightly below average snowpack and minor spring precipitation, all <br />ponds paztially filled during April and May. Most of the ponds retained some water through October, <br />' except for the ponds associated with Stations 303 and 321, which were dry by the end of July. The <br />only outflow during the 2003 water year was minor discharge at Station 305 during May and negligible <br />spillage to several discharge structures due to wave action 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 eliminated from the monitoring program in October 1999. No data was collected from any <br />of these sites during the 2003 water year. <br />MWH * 1475 Pine Grove Rd., Ste. 109, * Steamboat Springy Colorado 80477 * (970) 879-G260 <br />u-aum~r;,., e..nas>,n...ania 0.r^nmas~nros+ri~n av^ <br />snn/w m <br />
