Pavement repairs continue on northern Arizona highways after storm

Posted on by

PHOENIX – After another snowstorm earlier this week, Arizona Department of Transportation maintenance crews are patrolling northern Arizona highways to locate and address potholes while they conduct more involved pavement repairs on stretches of Interstate 40 west of Flagstaff.

Crews will lay asphalt over existing pavement to smooth rough sections of I-40 at milepost 86 westbound and milepost 98 eastbound between US 93 and Seligman, as well as between mileposts 170 and 177 eastbound, about 10 miles east of Williams.

In addition, maintenance workers are patrolling the following stretches of highway to locate and fill any potholes:

  • I-40 between mileposts 82 and 139, from approximately 10 miles east of US 93 to six miles west of SR 89;
  • US 180 between mileposts 215-248, from Flagstaff to 13 miles past Kendrick Park;
  • and State Route 89A between mileposts 375-386, from Sedona to a couple miles before the switchbacks.

Potholes can pop up quickly when moisture seeps into and below asphalt, which in northern Arizona can be stressed by the combination of freezing overnight temperatures and daytime thawing. The Flagstaff area usually experiences more than 200 daily freeze-thaw cycles each year. Add heavy traffic, and this stressed pavement can break away.

ADOT has two projects coming later this year along I-40 between Flagstaff and Williams that will add a new layer of pavement in both directions.

AZGFD monitoring threadfin shad die-off at Apache Lake

Posted on by

PHOENIX – The Arizona Game and Fish Department recently investigated a fish die-off of thousands of threadfin shad at Apache Lake in the Tonto National Forest.

AZGFD collected water samples on Tuesday, Feb. 28 and determined the die-off was caused by a golden alga bloom largely restricted to the riverine portion of Apache below Roosevelt Lake.

Golden alga is not harmful to humans, and therefore Apache Lake remains safe for water activities, including fishing.

“Golden alga thrives on elevated salinity associated with drought conditions,” said Marc Dahlberg, Water Quality Manager at AZGFD. “Therefore, recent heavy rains will hopefully knock down salinity levels and help control golden alga blooms.”

At this point, AZGFD believes the fish kill has been restricted to threadfin shad and a few gizzard shad, both of which are highly sensitive to the toxin produced by golden alga.

The last such fish die-off in this region occurred in 2007, also in upper Apache Lake. However, there were significant fish kills caused by golden alga in Saguaro, Canyon and Apache during the early-to-mid 2000s that affected all fish species.

Fisheries biologists for the Department will continue monitoring water quality and fish health on all Salt River-chain lakes.

Kaibab National Forest plans pile burn near Jacob Lake

Posted on by

FREDONIA – North Zone fire managers plan to resume pile burning in the vicinity of the Arizona Department of Transportation Maintenance facility near Jacob Lake starting as early as Monday.

Pile burning is one piece of the ongoing hazardous fuels reduction efforts of the Plateau Facilities Fire Protection Project on approximately 5,000 acres surrounding 33 structures across the Kaibab Plateau. Fire managers plan to initially target 25 acres of piles and continue throughout the week as conditions allow.

As a reminder, all prescribed fire activity is dependent on the availability of personnel and equipment, weather and fuel conditions, including winds, temperature, humidity, vegetation moisture and ventilation conditions for dispersal of smoke. All prescribed fires are subject to approval by the Arizona Department of Environmental Quality. For additional information on the Smoke Management Division and to view prescribed burn authorizations for any given day, visit http://www.azdeq.gov/programs/air-quality-programs/smoke-management.

In the interest of safety, visitors are reminded to always use caution when traveling in the vicinity of prescribed fires, as firefighters, fire-related traffic and smoke may all be present. Although no significant smoke impacts are expected, visitors should always be cautious when driving in the vicinity of emergency vehicles operating in the area.

As the prescribed burn season continues through the spring, notifications of upcoming prescribed fires will be provided regularly through the following sources:
