UPDATE, 1:11 p.m. Thursday: The Halligan Fire is fully contained, according to the Larimer County Sheriff's Office.
The sheriff's office says it will remain on scene while others demobilize.
ORIGINAL STORY: There was no growth Tuesday night to the Halligan Fire burning northwest of Fort Collins, according to the Larimer County Sheriff's Office.
The fire is at 150 acres with 75% containment, the sheriff's office said around 4:15 p.m. Wednesday. Due to improving conditions, the Type 1 helicopter has been released but ground crews will continue to work the fire.
The fire is located about 2 miles north and west of Halligan Reservoir near where Dale Creek flows into the North Fork of the Poudre River, according to the sheriff's office.
One hundred personnel are working the lightning-caused fire that started late Monday evening in a remote and rugged area near Halligan Reservoir, about 30 miles from Fort Collins.
A Type 1 helicopter is being deployed, according to a tweet from the sheriff's office.

The National Weather Service in Boulder has issued a red flag warning from 11 a.m. to 7 p.m. Wednesday for the northeast corner of the state. The area is at increased fire risk due to high temperatures, low relative humidity, and wind direction and speed.
The warning extends to just east of Fort Collins and does not include the Halligan Fire area. Still, many of the same conditions that prompted the warning will exist at the fire Wednesday.
A Red Flag warning is valid today 29 June 2022 from 11am to 7pm. The highlighted areas indicate areas of increased fire risk due to high temperatures, low relative humidity, and wind direction and speed. Use extra caution when burning and take notice of any burn bans. #cowx pic.twitter.com/ckFzot7lPx

The weather service forecast for Fort Collins on Wednesday is a high of 95 with a northwest wind 7 mph to 12 mph in the morning becoming west-northwest 13 mph to 18 mph in the afternoon and gusts as high as 30 mph, which will hamper firefighting.
There is a 30% chance of showers and thunderstorms in the afternoon.
The sheriff's office said there were five lightning strikes in the area where the fire started Monday.
The city of Fort Collins owns the Halligan Reservoir dam and the land immediately surrounding and underneath the reservoir. The water in the reservoir is owned and managed by North Poudre Irrigation Company and primarily used for irrigation.
The city is monitoring the fire's movements for potential impacts to city-owned infrastructure.
