The snowpack over the San Juan Mountains&nbsp;in southern Colorado is&nbsp;less than 25% of normal for this time of year. The high country to the north is fairing much better, but&nbsp;basins are still only at 85% of normal. Thankfully, reservoirs are at or above normal across the state, which will help lessen the impacts of the low snow depth. While it&rsquo;s a bit early to tell what the fire season holds, rainfall this spring is imperative to help alleviate the developing drought over the southern portion of the state.<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2018\/05\/NRCS_snowpack.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-6745\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2018\/05\/NRCS_snowpack.png\" alt=\"\" width=\"775\" height=\"556\"\/><\/a><\/p>\n<p>There was no flooding reported Monday.
