Lap Lanes IllustrationLap Lane Etiquette

If the lanes are full, you may split or circle the lane. Observe each lane to get a sense of which one best matches your pace. Wait for the other swimmer(s) to finish their set, and then let them know you’ll be joining them. Decide together how you’re going to share the lane.

Splitting the Lane (for 2 swimmers): One of you swims on one side of the lane and one of you swims on the other. If you're splitting the lane, you stay in your half no matter what.

Circle Swim (for 2 or more swimmers): Much like traffic on a road, always swim on the right side of the lane. This means swimming on one side of the lane going down and the other side of the lane coming back. Swimmers move in a counterclockwise circle.

POOL POLICIES

Pool Closures

YMCA staff may close the pool at any time for safety reasons, including but not limited to:

  • Chemical imbalance
  • Mechanical issue
  • Water clarity
  • Pool contamination
  • Natural dangers (lightning or thunder within 10 miles will constitute immediate closure for no less than 30 minutes from the last lightning strike or sound of thunder)

The YMCA reserves the right to alter this list or limit activities to protect the members and guests of the YMCA of Northern Colorado. For your safety and the safety of others, please obey all verbal instructions from YMCA staff.

Guest fees will not be refunded due to weather-related closures.

Swim Test Policy and Rules

Anyone under the age of 12 is required to perform a safety swim test in front of one of our certified Lifeguards. This policy is aimed at identifying the swimming capability of our younger patrons to ensure their safety as well as the safety of other members. Each test level is pass/fail and may be retaken one more time per day. After passing the test, the swimmer’s full name and most recent level will be kept in our log book for one year.

Red Band

The swimmer refused to take the test or did not pass the test. This is a non-swimmer and must have a parent in the water within arms’ reach even if they are wearing a Coast Guard approved personal flotation device. No more than two children per adult.

Yellow Band

The swimmer must jump in at the five-feet deep water, tread water for 30 seconds, float on his or her back 30 seconds and then swim forward across half the length of the pool continuously.* Access to shallow end slides at the Arapahoe Y if height requirement is met (see slide rules) and access to shallow end at the Mapleton and Longmont Ys.

Green Band

The swimmer must jump in at the five-foot section, tread water for 30 seconds, float on his or her back 30 seconds and then swim forward the length of the pool without touching the bottom of the pool.* Swimmers with green bands are granted access to the diving boards and slides at the Arapahoe Y and to the full pool at the Longmont and Mapleton Ys.

*The swimmer may use any stroke or method that provides continuous forward movement without touching the bottom of the pool. If they swim underwater they must break the surface regularly to breathe. The swimmer does not have to use any specific breathing pattern or technique.

The determination of swimming capabilities and band color of all swimmers is at the discretion of the Lifeguards or the supervisor on duty. At any time, a Lifeguard or supervisor may retest or revoke the permissions of any swimmer for safety concerns or policy violation.
