Barton Springs stays a drought hotspot as the county map turns green

August 17, 2026Northern Blackland Prairie

Travis County's drought picture looks dramatically better than it did in January, when extreme-to-exceptional conditions blanketed the entire county and severe-or-worse coverage stayed pinned near 100 percent all the way through early June.¹ Since then the numbers have fallen fast: severe drought coverage dropped to about 66 percent by late June, then to roughly 16 percent through July, and now sits just above 10 percent, with no part of the county rated extreme or exceptional.¹ At the county scale, that is a genuine recovery.

But the map's green doesn't match what the water is doing at Barton Springs. Two weeks ago, streamflow on Barton Creek above the springs had dropped to near zero, and dissolved oxygen had fallen to 4.9 milligrams per liter, a level at which fish and aquatic insects start to feel real metabolic stress. Almost the entire county is still classified as abnormally dry, and nearly two-thirds remains in moderate drought, so the underlying dryness hasn't actually left, it has just eased out of the most severe categories.¹

Spring-fed systems like this one often run on a different clock than the surrounding land, since Barton Springs draws on the Edwards Aquifer. Whatever the exact mechanism, the pattern here is clear: the county's drought index is improving, but the creek above the springs is still running low and short on oxygen, a local hotspot that isn't tracking the broader rebound.¹

Waller Creek flow drops to zero in July drought

July 14, 2026

The creek ran dry this week. A month ago, flow measured 165 cubic feet per second — a modest but steady pulse through the summer channel. Now the gauge reads zero, and the aquifer springs that feed these karst streams have stopped flowing.When flow ceases, aquatic life has nowhere to go but the remaining pools. Fish, invertebrates, and plants compress into shrinking refuge pools where July heat climbs toward 100°F and oxygen crashes. These congested refuges become ecological traps — temporary, stressed, unsustainable. The creek's impaired waters listing exists precisely for moments like this, when the system can no longer support the life it normally carries.Karst streams in summer depend entirely on springs. Once the aquifer stops delivering water, collapse comes fast.

Sharp-shinned hawk hunts through summer neighborhoods

June 12, 2026

The morning air carries the soft chip notes of kinglets through the residential canopy near Austin, where live oaks spread their broad crowns over sidewalks and driveways. Ruby-crowned kinglets move through the upper branches in quick, nervous hops, their olive backs catching the early light as they glean insects from the undersides of leaves. These small birds are uncommon here in summer, lingering briefly as they follow migration routes that carry them far beyond Texas heat.A sharp-shinned hawk materializes between the houses, its short wings beating in rapid bursts before it glides low through the yard spaces. This small raptor moves like water through obstacles, threading between fence posts and porch railings with a precision that transforms suburban geometry into hunting ground. Sharp-shinned hawks are built for pursuit in tight spaces. Their long tails act as rudders, their compact bodies slip through gaps that would stop larger raptors. In summer, when most of their kind have moved north to breed, this individual has stayed to exploit the brief abundance of migrating songbirds that pause in Austin neighborhoods.The hawk's presence changes everything. Kinglets that were feeding openly moments before now freeze against bark, their movements reduced to the smallest necessary adjustments. A least flycatcher, another uncommon summer visitor, abandons its perch on a redbud branch where the tree's heart-shaped leaves provide little cover. These small flycatchers normally dart out to catch insects in midair before returning to the same perch, but the hawk's arrival breaks this rhythm. The flycatcher drops into the dense growth of American beautyberry, where purple flower clusters are just beginning to form and the layered branches offer better protection.The relationship between this hawk and its prey operates on split-second timing. Sharp-shinned hawks hunt by surprise, using cover to approach within striking distance before launching into open pursuit. Their short, rounded wings generate quick acceleration but sacrifice the sustained speed of larger raptors. This means the chase must be decisive. Either the hawk catches its target in the first rush, or the songbird reaches cover and escapes. Kinglets and flycatchers have evolved responses to this pressure. They feed with constant awareness, heads turning frequently to scan for movement. When threatened, they drop into dense vegetation where the hawk's advantage disappears.The summer neighborhoods provide an unusual hunting ground for this hawk. Residential plantings create a patchwork of open areas and thick cover, with bird feeders and flowering shrubs concentrating small birds in predictable locations. The wax mallow blooms are drawing insects, which in turn attract the flycatchers and kinglets. These temporary abundances give the sharp-shinned hawk opportunities that would not exist in more uniform habitat. The bird moves between yards like it knows the territory, appearing suddenly at the edge of one property before vanishing behind a garage and emerging in the next block.Somewhere above you now, if you are standing beneath trees, small birds are making calculations about safety and hunger. The morning light filters through leaves that are fully expanded in the summer heat, creating the shifting patterns of sun and shadow that both predator and prey use to their advantage. Listen for the thin contact calls of kinglets, the sharp notes that keep a feeding flock connected as they move through the canopy, always ready to disappear.

Mealycup sage and the threatened bumble bee

May 28, 2026

The purple spikes of mealycup sage rise from the understory near downtown Austin, their tubular flowers opening in sequence from bottom to top. Each bloom holds nectar deep in its throat, accessible only to pollinators with tongues long enough to reach it. The air carries the faint herbal scent of the sage's leaves, crushed underfoot as you move through the native plantings.American bumble bees work these flowers with methodical precision. The threatened species has found reliable forage here as the sage enters its peak bloom period. A worker bee grips the lower lip of each flower, her weight pulling it down to create a landing platform. She inserts her tongue into the narrow tube, probing for nectar while pollen dusts her fuzzy back from the stamens positioned just above. The bee's body is large enough to trigger the flower's mechanism, ensuring both parties benefit from the exchange.This partnership unfolds during a critical time for the bumble bee colony. Queens emerged from winter hibernation weeks ago and have already established underground nests in abandoned rodent burrows or dense grass clumps. They are now deep into egg-laying, building their colonies one cell at a time. The first generation of workers has hatched and taken over foraging duties, allowing the queen to focus entirely on reproduction. These workers must gather enough nectar and pollen to feed developing larvae and sustain the growing colony through summer. The mealycup sage provides consistent, high-quality nectar during this essential phase when the colony's survival depends on steady food sources.The sage benefits equally from this arrangement. American bumble bees are among the most effective pollinators of native Texas plants, their large bodies and dense fur collecting and transferring more pollen than smaller insects. Unlike introduced honey bees, which often rob nectar from the side of flowers without pollinating them, bumble bees consistently work flowers from the front, ensuring cross-pollination between plants. The sage's extended blooming period, lasting several weeks, provides multiple opportunities for successful fertilization and seed set.Other native plants nearby offer additional forage as the season progresses. Upright prairie coneflower shows early buds that will soon open into yellow petals around dark centers, extending the nectar flow. American beautyberry and wax mallow hold their leaves in full expansion, preparing for their own flowering cycles later in the season. This succession of native blooms creates an unbroken chain of food sources that supports the bumble bee colony through its complete life cycle.
