Pool service in Lost Creek

Sullivan’s services pools in Lost Creek, the wooded neighborhood west of Loop 360 and north of the Barton Creek greenbelt. Lost Creek pools are mostly of an age now where the original equipment has already been replaced once, and the question is usually which component is next rather than whether anything is due. Dense cedar makes the December-to-February stretch the demanding part of the year.

Where Lost Creek is, and what the ground does

Lost Creek runs about two and a quarter miles across. Its residential streets run from 656 ft to 976 ft above sea level — a fall of 320 ft along the streets themselves, and 400 ft boundary to boundary. The difference is the ground the houses are not on — greenbelt, gorge or park. The contour lines on the map are the same survey those numbers come from, and they cover the full frame.

Lost Creek’s streets run from 656 ft to 976 ft — a 320 ft fall

That drop happens in two miles, and it all runs one way: down to Barton Creek, the one named watercourse inside the boundary. Pools here sit at the bottom of their own small catchments, which is why the filter is the thing that decides whether the water stays clear. Everything that washes off a limestone slope in an Austin downpour — grit, cedar litter, decomposed granite off the drives — ends up in the pool at the bottom of it, and a cartridge that would run three months flat somewhere else runs six weeks here.

The creek draining this ground is Barton Creek. Creek-side pools in Austin get two things the rest do not: more organic debris blowing off the corridor, and a faster, dirtier rise after a storm. Both are chlorine demand, and both are why a pool a street from the creek and one four streets away are not the same weekly job.

What Lost Creek is like to work in

When it was built
Mainly 1970s and 1980s, with pools of a similar vintage now on their second or third set of equipment.
The lots
Hilly and wooded, backing onto greenbelt in places.
What falls in
Dense cedar. This is one of the heavier winter debris neighborhoods we work.
Getting to the pool
Winding streets and sloped driveways; straightforward once known.

What we watch for here

  • Equipment here is typically on its second generation — the useful information is which part is oldest, not whether the pool is “fine”.
  • Cedar drop is heavy enough between December and February that basket capacity, not chemistry, is the limiting factor.
  • Greenbelt backing lots collect more organic debris, which drives chlorine demand up in ways the pool size does not predict.

The ground under Lost Creek

Edwards limestone, west of the Balcones Escarpment. Thin soil over rock, steep lots, and a canopy of live oak and Ashe juniper. Decks stay put, but the leaf and pollen load is heavy from December through April and skimmer baskets fill fast.

Lost Creek — questions people ask

Do you service pools in Lost Creek?

Yes — Lost Creek is on our West Lake Hills route and we are there weekly. Pool and spa service, equipment repair, and recovery work when a pool has gotten away from someone.

Why does my Lost Creek pool need more chlorine in winter?

Organic load. Cedar and oak drop heavily here from December, and every leaf that sits in the water consumes chlorine as it breaks down. It is not unusual for a shaded, greenbelt-backing pool to have higher demand in February than a sunny open pool has in July.
