Mandatory Boat Inspections for ANS at Lake Pueblo

To boat on the reservoir, an aquatic nuisance species (ANS) stamp, current boat registration and a pre-launch boat inspection at the boat ramp is required.

Vessels and other floating devices that are both hand-launched and human-powered are exempt from mandatory ANS inspections. Although, the public is strongly encouraged to self-inspect their watercrafts, boots, waders, and fishing equipment by making sure that all equipment is clean, drained, and dry.

Important: Eurasian watermilfoil has been detected in Lake Pueblo. This aquatic noxious weed forms dense mats which restrict swimming, fishing, and boating.

The following hours are effective April 1 through October 15, 2025:

  • North ramp inspections: 5 a.m. to midnight
  • South ramp inspections: 5 a.m. to 10 p.m.
  • Decontamination: 8 a.m. to 7 p.m.

Boats may stay on the lake 24 hours a day with proper lights, but they may only launch or load during ramp/inspection hours. You must be AT THE STATION with your boat before closing time to receive your inspection and seal.

Winter Weather Closure Procedure

In an effort to standardize our response and to ensure everyone’s safety when winter weather conditions are present at the ramp, we follow the following protocols:

Weekdays (Mon-Thurs): If the schools in Pueblo West District 70 are closed due to bad weather, the inspection stations will also be closed. If the schools are on a two hour delay, our inspection stations will open at 9 am.

The information regarding school closings in D70 is widely reported on local television and radio stations. Closing notices are also available at www.district70.org. This applies to the Pueblo West schools in District 70 and not the mountain schools.

Weekends (Fri-Sun): If snow and icy conditions exist, it is likely that we will be on, at least, a delayed opening of 9 am. To confirm this before 9 am, please call the non-emergent CSP dispatch number: (719) 544-2424 for ramp details. After 9 am, please call our Visitor Center at (719) 561-9320 for the information.

As always, inspection stations may be closed early due to adverse weather conditions that arise during the day or other unexpected circumstances.
