Harris County Flood Control District Continuing to Monitor Bayou and Creek Conditions

The Harris County Flood Control District is continuing to actively monitor impacts to bayous and streams from what is now Tropical Storm Nicholas. Rainfall amounts overnight have averaged less than 2.0 inches over northwest Harris County to us much as 5.0-6.0 inches over Clear Creek in the southern portions of the county.

Minor flooding is ongoing along Clear Creek from Bay Area Blvd to Clear Lake due to upstream rainfall run-off and high tides levels in Clear Lake due to storm surge flooding earlier this morning. The creek has crested and water levels are falling.
