Fort Morgan residents will be able to cultivate and enjoy green lawns and gardens this summer if they want to do so.
That is thanks to the increase in the Colorado-Big Thompson water quota announced Thursday and the resulting likelihood of no city lawn-watering or residential-water-use restrictions in coming months, according to Fort Morgan Water Resources/Utilities Director Brent Nation.
The Northern Colorado Water Conservancy District Board of Directors on Thursday approved increasing the Colorado-Big Thompson Project water pipeline quota to 70 percent, according to a news release. The Northern Water Board had set it at 50 percent last November.
Fort Morgan receives its water from that pipeline, with water availability subject to the quota set periodically by the Northern Water Board. This quota change does not affect city water rates, which are set by the Fort Morgan City Council. It only affects the amount of water available to the city for use.
But this new quota is one that still means good news for Fort Morgan water customers, according to Nation.
“I am pleased that the C-BT quota has been set at 70 percent for this water year,” he said Thursday afternoon. “70 percent allows our businesses and residents to enjoy high quality water with no restrictions.”
Here’s the release from the Mountain Studies Institute:
The fact that people in the community noticed when the Animas River was distinctly yellow-brown in color on February 15, 2016 reflects a heightened awareness of changes in water quality since the Gold King Mine release. Warm temperatures in mid-February initiated the first increase in runoff since last fall’s storms, picking up sediment in the process.
Mountain Studies Institute (MSI), a nonpartisan independent research station, has been monitoring water quality of the Animas River since before, during, and after the Gold King Mine release. MSI received lab results back from water quality samples collected from the Animas River at Rotary Park on February 15, and March 1, 2016.
“These samples are the first in a series of sampling that will occur as part of a monitoring program that aims to understand changes in water quality during 2016 storm events and spring runoff” said Scott Roberts, MSI’s aquatic ecologist. The monitoring program is part of a partnership between MSI and the City of Durango to convey Animas River water quality information to the public.
“Because we know that people are curious to see the data, MSI has posted water quality monitoring results and an explanation of those results on our website, http://www.MountainStudies.org” said Marcie Bidwell, MSI’s director. “By posting updated information on our website, we hope to keep the public informed as the season progresses. Links will also be available on the City’s website, http://www.durangogov.org.”
Results from the spring samples indicate some encouraging news. Metals of concern for human health (Arsenic, Lead, and Mercury) and those thought to be most harmful to aquatic life (Copper, Zinc, and Selenium) were found to be at levels considered safe by Colorado Department of Health and the Environment (CDPHE) water quality standards. All metals analyzed from these two spring samples were at levels considered safe for agriculture and domestic water supply use (based on CDPHE water quality standards). Additionally, all metals were below Environmental Protection Agency’s recreational screening levels, which represents the level at which no adverse health effects are expected to occur in humans consuming 2 liters of filtered water per day, from the Animas, orally, for 64 days each year for a total of 30 years.
However, the yellow-brown color of the Animas River at Rotary Park in Durango on February 15th did contain high levels of certain metals. Concentrations of Aluminum and Iron surpassed chronic water quality standards set by CDPHE to protect aquatic life from persistent, long-term exposure to metals. The brief exceedances of chronic water quality standards from one sample on one day do not necessarily indicate potential harm to aquatic life unless these levels persist continuously over a 30-day period.
The visible yellow or orange color of the river is mostly Iron and Aluminum. Iron particles of various sizes are suspended in the water column. Other metals, such as Zinc, readily bond to the Iron particles.
“MSI’s data supports the conclusions of local, state and federal partners that, from a public health standpoint, this year’s spring runoff is unlikely to be different from previous years. Monitoring and notification procedures are also in place to notify the public if conditions change.” said Liane Jollon, executive director of San Juan Basin Health (SJBH). “SJBH advises the public that it is always good practice to wash with soap and water after exposure to any untreated body of water, including the Animas River. Further information and more health tips for river users are available on our website at http://sjbhd.org/public-health-news/animas-river-health-updates/.”
In a partnership with the City of Durango, MSI plans to continue to monitor the water quality of the Animas River throughout 2016, focusing on understanding chronic exposure to aquatic life before runoff, during runoff, and into the summer season.
Please keep in mind that these observations are from only one location (Rotary Park in Durango) on the Animas River and may not be indicative of the entire Animas River watershed.
Runoff from autumn storms kicked up the levels of some contaminants in a southwestern Colorado river after a massive spill of toxic mine waste, but concentrations of other pollutants declined or didn’t change, researchers said Friday.
A report released by the Environmental Protection Agency could offer clues about what will happen to the Animas River this spring and summer when melting snow from the San Juan Mountains makes the waterway run higher, potentially stirring up pollutants that had settled to the bottom after the spill.
But the researchers said they couldn’t be sure that the pollutants they measured came from the Gold King Mine — source of the 3-million-gallon spill last August — or if they were from other mines that riddle the area. They also said they didn’t have enough historical data to know whether storms that hit after the Gold King spill stirred up more pollutants than ones before it…
Most of the metals settled to the bottom of the Animas before reaching the San Juan River in New Mexico, the EPA said. Experts have differed on whether and how much those metals will be stirred up when river flows increase after storms and from the spring snowmelt.
The nonprofit Mountain Studies Institute in Silverton monitored the river for the EPA in Durango, Colorado, about 60 miles downstream from the mine, and compiled a report.
Seven storms increased the flow of the Animas in Durango between Aug. 9 and Oct. 26. Concentrations of six contaminants increased after some of those storms, including aluminum and copper, the institute’s report said.
Levels of mercury and five other contaminants decreased after some storms, while the levels of seven others didn’t change.
State water officials don’t expect floods or above-normal flows in the Animas this spring and summer. The San Juan Mountain snowpack that melts into the river was only 66 percent of the long-term average on Friday.
Even if a weekend storm drops up to 2 feet of snow on the San Juans as predicted, it probably won’t be enough to cause the Animas to flood, said Kevin Houck, chief of watershed and flood protection for the Colorado Water Conservation Board.
