Connor Stockert, 16, keeps his balance as a wave generated at the Wachter Aquatic Complex crashes against his back when Friday's temperature reached 102 degrees. The National Weather Service in Bismarck predicts a high of 88 degrees today. Temperatures were slowly creep upward to the week's end with a high of 94 degrees on Friday.

Bismarck’s outdoor pools will begin to close for the season, with two slated to pull the plug this weekend.

Wachter Aquatic Complex, 205 Reno Ave., will close at the end of the swim session at 7 p.m. Friday.

On Saturday, the pool will host a dogs-only swim event from noon to 2 p.m. Small dogs weighing less than 30 pounds are welcome to swim the first hour, followed by the “Big Dog Party” for pooches weighing more than 30 pounds from 1 to 2 p.m.

All pool chemicals will be turned off 24 hours prior to the “Pool Pooch Party,” according to Bismarck Parks and Rec, to ensure the dogs’ safety. The waves will not be turned on for this event.

Dog handlers will be asked to sign a waiver upon entrance and will be allowed to wade in the pool in ankle- or calf-deep water.

The event is free, but donations will be accepted to support improvements at the Century Bark Park.

The Elks Aquatic Center, 321 W. Broadway Ave., will close for the season at 7 p.m. Sunday.

The Hillside Aquatic Complex, 1719 E. Boulevard Ave., will remain open one week longer than the Elks pool, closing at the end of the swim session at 7 p.m. Aug. 19.

For the remainder of the season, pool hours are noon to 4 p.m. and 4:30 to 8 p.m. Monday through Thursday, and noon to 7 p.m. Friday, Saturday and Sunday.

The swim fee is $3.50 per session. Use of the water slides at the Hillside Aquatic Complex is an additional $1.50.
