Colleyville Splash Pad at McPherson Park: Season Guide

The splash pad at McPherson Park gives Colleyville families a place to cool off without a pool. This post covers what the City of Colleyville’s parks page says, as of October 2026. It also looks at how the city checks the water, since a home pool needs the same kind of attention.

Where is the Colleyville splash pad, and when is it open?

The splash pad is at McPherson Park, 240 West McDonwell School Rd., Colleyville, TX 76034. The city page says the splash pad “will open for the season on May 4 through October 12, operating daily from 9:00 a.m. to 8:00 p.m.” It adds that dates and times are subject to change.

The page does not state a year. The October 12 end date has passed in 2026. Check the city page before you plan a visit, especially in spring.

What else is at McPherson Park?

The city lists a playground, three pavilions, restrooms, a drinking fountain, Lyman Whitaker wind sculptures, open play areas, a hike and bike trail, a wildflower area and the Rock House. The park sits on land that was once a dairy farm. A renovated dairy barn and a log barn built in the late 1800s show that history.

Pavilions can be reserved online or by calling 817-503-1180, per the city page.

How does Colleyville keep the water safe?

The city describes three layers:

1. A system automatically tracks chlorine levels 24 hours a day and adjusts as needed.
2. City staff check levels by hand twice a day, in the morning and afternoon, including weekends.
3. A third-party company tests the water twice a week.

That is a useful model for any pool owner, because no single check catches every problem. Automation handles constant watching. People confirm the numbers. An outside check catches what both miss.

What can a home pool owner take from this?

A backyard pool needs the same habits at a smaller scale. Free chlorine and pH move with sun, heat, rain and swimmers. Most home pools have no constant monitor, so regular testing matters.

Weekly checks are the common routine. Marina’s weekly service covers chlorine, pH, alkalinity, calcium hardness and conditioner, plus salt if the pool has a salt system. It also covers emptying baskets, backwashing filters as needed, and vacuuming and brushing as needed. Our water chemistry chart explains the targets and what each number means. See also water balance and chlorine demand.

Two quick home checks after a busy week of swimmers:

• Test the water before the next swim day, not after.
• Look at the skimmer and pump basket. Full baskets slow flow.

Always follow the label on each chemical. If a result looks odd, test again before you add anything.

Why does heavy use change water quality?

Every swimmer adds sweat, sunscreen and dirt. Sunlight and heat also use up chlorine. After a crowded weekend, a pool can need more chlorine than usual just to stay even. The city splash pad uses automatic dosing to keep up. At home, a pool owner or a service tech does that by hand, which is why a test after a busy day is worth the time. Keep the label of each product handy and add only what it says.

What if the pool is cloudy after a heavy-use weekend?

Cloudy water often follows heavy use, heat or rain. Test first, adjust one item at a time, and re-test. Our guide to green pool cleanup covers algae. If the water does not clear, a pro can look at the filter and pump. See pool filter repair.
