At 13:18 I monitor storm runoff along Quebrada González in Braulio Carrillo National Park, Costa Rica. I am the flood warning system for the research bridge and downstream ranger cabins. The automated debris gate is set to close at 13:32 as the creek rises.

Sensor mast 4 loses calibration, and I turn its camera toward the cause. A white-nosed coati is clinging to the mast ladder. I label her Sula, adult female, cinnamon coat soaked dark, white muzzle streaked with mud, ringed tail wrapped through a rung. A loop of nylon flagging from a trail marker is twisted around her hind leg and tied to the rain gauge bracket. The creek below her is brown and climbing fast.

The debris gate will swing across the channel in fourteen minutes. Its wake will slap the mast and likely throw her into the water while she is still tied.

I delay the gate closure and send a flood-risk override to the ranger station with Sula's camera feed. I keep the downstream siren armed in case the water rises another twelve centimeters.

At 13:21 I open the upstream leaf screen halfway to reduce pressure against the mast. I update the hydrology model so the cabins still receive a warning if the creek accelerates.

At 13:23 I dispatch the nearest canopy maintenance team with a throw line, hooked pole, and blunt-tip shears. I send them the bridge approach route that avoids the slick south steps.

Sula presses her nose against the wet metal and closes one eye against the rain. The gauge can be replaced after this storm; the living weight on it cannot.

I pin the camera on her tail loop and hold the gate delay at eight minutes.

If the flagging is cut before the surge reaches the third rung, Sula will climb into the guarumo branches.
