There鈥檚 an eerie stillness inside a wildfire burn scar. The ground, once lush with life, is a gray mat of ashy soil. There are no leaves or needles to rustle in the breeze. The trees are little more than blackened toothpicks, reduced to their skeletons.
But in the Cameron Peak burn scar, the faint hum of a whirring helicopter echoes for miles off the canyon walls.
It鈥檚 been almost exactly a year since the Cameron Peak Fire tore through the foothills outside of Fort Collins, Colorado, on its way to becoming the largest fire in state history. Now, restoration efforts are underway. About 1 million people rely on water moving through this canyon, and one of the most effective ways to protect the area鈥檚 watershed uses these helicopters. Instead of scooping up water to drop on flames, pilots dip low and pick up bulging nets full of wood mulch to dump on the charred hillside.
Randy Gustafson, water resource administrator for the City of Greeley, looks on as a helicopter hovers near the ground, rumbling loudly over a pile of mulch bigger than a house. Then, it鈥檚 off as quickly as it came, zipping back and forth into the burn scar with heaving payloads in tow.
鈥淚鈥檓 kind of used to it, and still,鈥� he said, 鈥渢he kid in you comes out watching this.鈥�
Even though Greeley is a two-hour drive away from this 鈥渁erial mulching鈥� operation in Poudre Canyon, this is where the city鈥檚 water comes from. Snowmelt and rain make their way down from the foothills into the Cache la Poudre River before that water is piped over to the city. But Gustafson said a charred slope is slick like a frying pan. Water will run off of it, carrying dirt, ash and other debris into that water supply. So his team has to stabilize the hillside with mulch.
鈥淚 look at the Poudre as a living organism,鈥� Gustafson said. 鈥淗ow do you keep it functional and operational and make it produce good, clean water for everybody down below?鈥�
Gustafson's team is just one part of the city鈥檚 strategy to keep the water clean. Another effort is underway above Chambers Lake, less than a mile from where the fire began. Here, fire debris threatens to cause harmful algae blooms in the reservoir. So big bundles of spongy wood shavings, held together by biodegradable nets, are laid out on the hillside.
鈥淭hey form a baffle,鈥� Gustafson said. 鈥淭hey stop the debris, soil, ash, and keep it from coming down into the reservoir.鈥�
On a visit to the site, Gustafson shows how the baffles are successfully holding back sludgy piles of gray dirt in one of the most severely burned parts of forest.
鈥淭his makes it worth it,鈥� he said. 鈥淭his makes what we鈥檙e doing worth it. This is a microscopic portion of what we have. It stopped the bleeding. This gets me amped up.鈥�
In the grand scheme of things, though, these efforts could be little more than a Band-Aid. The expensive and time-consuming mulching work can only cover a fraction of the burn鈥檚 sprawling footprint. And more are likely on the way.
鈥淭hese megafires are unfortunately not going to be going anywhere anytime soon,鈥� said Hally Strevey, director of the Coalition for the Poudre River watershed. 鈥�We鈥檙e trying not to lose hope. There are plenty of things we can still do, working together collaboratively.鈥�
That includes her organization鈥檚 precautionary forest management in areas prone to burning. The fact it鈥檚 carried out by a watershed group just further emphasizes how deeply water and fire are connected. Even after a fire is put out, it takes a lot of work to keep the water clean.
But restoration projects like the one in Poudre Canyon are not cheap. Keeping just one helicopter in the air costs $87 per minute. Greeley鈥檚 deputy water director, Adam Jokerst, says the high costs are worth it for two reasons.
鈥淥ne is to protect the public,鈥� he said. 鈥淢ulching and other erosion control structures reduce flooding and protect life and property. And the second reason is water quality. How much is clean, pure mountain water worth?鈥�
Jokerst said Greeley gets the best 鈥渂ang for its buck鈥� from aerial mulching, but they might not have enough money to cover as many acres as they鈥檇 like to.
鈥淲hat鈥檚 most critical now is lack of funding. We鈥檙e spending roughly $300,000 a day. We go through money very quickly,鈥� he said.
The money spent on recovery work is also a precautionary measure against purification costs that could be incurred if ash finds its way into the water supply.
鈥淚f we don鈥檛 do this mitigation work,鈥� said Jen Petrzelka, Greeley鈥檚 water right鈥檚 manager, 鈥渨e will see increased water quality issues that create increased costs because we need more chemicals. That could be reflected on your bill. But by doing this work, we are doing our best to keep our ratepayers鈥� bills steady and not see any increases.鈥�
With a long list of tasks to protect more of the watershed, Jokerst said they could use more help from state and federal infrastructure spending 鈥� which would then be matched by city funding. He would also like to see more permanent funds set aside for this type of work. Randy Gustafson would too, especially since wildfires are getting stronger and more frequent.
鈥淚n the last 10 years, I鈥檝e had two major fires and both of them are the most severe fires we鈥檝e had,鈥� Gustafson said. 鈥淎nd I see this as continuing until we have nothing left to burn.鈥�
Greeley鈥檚 water team says restoration work will carry into the next few years, but because of the size and severity of the burn, it may never truly be the same as it was before the fire.
