Galena fire: Northern Water installs debris booms to mitigate effects to Horsetooth Reservoir #codrought


From the Loveland Reporter-Herald (Pamela Dickman):

Northern Water, which oversees the Colorado-Big Thompson water stored in Horsetooth, installed debris boons in 10 locations of Lory State Park to catch any debris, mud or ash before it reaches the reservoir. Crews from the water district will monitor the traps and clean them out to make sure they protect the water.

Similar measures were taken after the High Park Fire and have worked successfully, said Amy Johnson, project manager for Northern Water. The district spent about $15,000 and completed the work in two days, Wednesday and Thursday.

“The reason we started work so quickly was the precipitation forecast this weekend,” said Johnson. “We want to get his in place before any significant runoff.”

The soils are still porous, so some water will absorb to feed grasses expected to sprout this season alongside trees parks staff will plant in the Galena and High Park zones.

“When we get rain and sunshine, we will get grass,” said Butterfield. “It’s going to green up pretty quickly for us, and every little bit of moisture helps.”

From the Fort Collins Coloradoan (Robert Allen):

Ten booms — mesh bags full of wood chips — were placed this week in park drainages to filter moisture entering Horsetooth Reservoir. “They’ll hopefully trap sediment and ash,” said Amy Johnson with Northern Water, adding that similar booms were placed in areas of the park affected by last summer’s High Park Fire. The Galena Fire burned at a lower intensity than the earth-scorching High Park Fire, and the charred remains aren’t expected to have near the impact on water quality.
