In spring 1978, the reservoir northeast of Durango was near capacity at 120,000 acre-feet.<\/p>\n<p>The other year of exceptional drought in recent memory and the lowest water year on record \u2013 2002 \u2013 brought water levels in Vallecito Reservoir to just under 15,000 acre-feet. Two years later, the reservoir was almost full again, hitting 120,000 acre-feet.<\/p>\n<p>This year will go down as the second-lowest water year in recorded history. But despite the lack of precipitation, the lowest Vallecito Reservoir got was about 21,700 acre-feet around Oct. 3, Canterbury said.<\/p>\n<p>But already, an uptick in moisture in October has the region\u2019s reservoirs rising. To date, a weather station at the Durango-La Plata County Airport has recorded nearly 2 inches of precipitation this month. (Just 6 inches of rain have been recorded at the weather station for the entire year.)<\/p>\n<p>As a result of the recent moisture, Vallecito is back up to 24,100 acre-feet.<\/p>\n<p><figure class=\"wp-block-image naviga-inline-image\"><img decoding=\"async\" src=\"https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=d225a92f-1539-4d18-84b1-25e8db382d5c&amp;function=cover&amp;type=preview&amp;source=false&amp;width=2000\" srcset=\"https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=d225a92f-1539-4d18-84b1-25e8db382d5c&amp;function=cover&amp;type=preview&amp;source=false&amp;width=800 800w, https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=d225a92f-1539-4d18-84b1-25e8db382d5c&amp;function=cover&amp;type=preview&amp;source=false&amp;width=1200 1200w, https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=d225a92f-1539-4d18-84b1-25e8db382d5c&amp;function=cover&amp;type=preview&amp;source=false&amp;width=1800 1800w\" sizes=\"(max-width: 480px) 100vw, (max-width: 1024px) 100vw, 2000px\" alt=\"Lemon Reservoir, northeast of Durango, hovered around 10 to 15 percent capacity this fall after the second lowest water year on record.

The reservoir, also northeast of Durango, hit a low of about 5,670 acre-feet in the first week of October.<\/p>\n<p>Efforts to reach the Florida Water Conservancy District, as well as the Florida Ditch Co., both of which deal with water out of Lemon Reservoir, were unsuccessful.<\/p>\n<p>McPhee Reservoir gained 2,000 acre-feet in October due to recent rains in the Dolores River Basin, said Mike Preston, general manager for the Dolores Water Conservancy District. The reservoir is currently holding about 169,000 acre-feet, with just 19,000 acre-feet of active storage. The inactive pool is 151,000 acre-feet.<\/p>\n<p>This time last year the carryover into the next water year was 137,000 acre-feet of active storage, thanks to the above average previous winter of 2016-2017. But the historic dry winter of 2017-2018 produced less than 50 percent of average snowpack, and farmers survived off of the previous year\u2019s carryover storage. A full active storage supply for McPhee is 240,000 acre-feet.<\/p>\n<p>Preston said there are two encouraging factors going into this winter. First soil moisture levels for the foothills and mountains are improved compared to last year\u2019s deficit at this time, so when the snowpack releases in Spring, more of it will drain into the reservoir rather than into the soil. Second, the El Ni\u00f1o weather phenomenon is setting up in the Equatorial Pacific, which tends to push storms on a more southerly track with a better chance of hitting Southwest Colorado.<\/p>\n<p>\u201cWe used up all of our carryover this year, so we need an average to above average winter to meet allocations,\u201d he said. \u201cA good foundation of soil moisture has been laid down and that sets the stage for building a good snowpack for the reservoir. We already have snowpack above 10,000 feet.\u201d<\/p>\n<p>PRID\u2019s Canterbury, however, said Vallecito is gaining ground.<\/p>\n<p>\u201cAs long as we get some snow, we have a good drainage and we should recover pretty quickly,\u201d he said.<\/p>\n<p>In a normal water year, water managers will set releases out of Vallecito Reservoir to about 30 cubic feet per second \u2013 the lowest level that can generate hydroelectric power.<\/p>\n<p>But this year, because there was not enough water to go around, Canterbury said releases will be set to about 5 cfs, which will set the dam into a \u201cfree spin\u201d \u2013 meaning it\u2019s not generating power.<\/p>\n<p>\u201cOnce we do that, we ought to start filling even better,\u201d he said. \u201cAnd of course, we\u2019ll keep doing our rain dance.\u201d<\/p>\n<p>Warren Gabbert, water commissioner for with Colorado Division 7 of Water Resources, said ditches supplied by Vallecito Reservoir ran about 70 to 80 percent of what they would normally run in a good water year.<\/p>\n<p><figure class=\"wp-block-image naviga-inline-image\"><img decoding=\"async\" src=\"https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=dda6e274-c6bf-46af-9462-93bd14500cae&amp;function=cover&amp;type=preview&amp;source=false&amp;width=2000\" srcset=\"https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=dda6e274-c6bf-46af-9462-93bd14500cae&amp;function=cover&amp;type=preview&amp;source=false&amp;width=800 800w, https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=dda6e274-c6bf-46af-9462-93bd14500cae&amp;function=cover&amp;type=preview&amp;source=false&amp;width=1200 1200w, https:\/\/imengine.public.prod.dur.navigacloud.com\/?uuid=dda6e274-c6bf-46af-9462-93bd14500cae&amp;function=cover&amp;type=preview&amp;source=false&amp;width=1800 1800w\" sizes=\"(max-width: 480px) 100vw, (max-width: 1024px) 100vw, 2000px\" alt=\"After a wet October, Vallecito Reservoir is already filling up, but it has a long way to go.
