<br />003462 <br /> <br />Results <br /> <br />o The number of seedable storms identified each winter from <br />interpolated soundings did not vary much in the wet, normal or <br />moderately dry winters studied. Neither did the percentage increase <br />in the water content of seasonal snowfall expected in various <br />drainage basins in four mountainous sub-regions of the state if all <br />eligible storms were seeded. This percentage increase ranged from <br />2.5 to 10.5 percent. These estimated increases are probably <br />conservative because some seedable storms may not have been <br />detected. Results of scientific field experiments indicate that <br />water content increases of 10 to 15 percent are possible. <br /> <br />Conclusion <br /> <br />o Seeding appears to offer comparable percentage increases in mountain <br />snowpack in moderately dry, normal and wet winter-s. While the <br />amount of additional snow expected from seeding may be lower in dry <br />winters than in wet ones, its value to the state's water-users in <br />dry winters may be substantial. <br /> <br />3 <br />
