Handy Web Sites to Monitor Flooding

After Harvey, the SJRA, Harris County, National Weather Service and USGS added and upgraded stream gages throughout the region. Think of these gages as a distant early warning system. Looking at upstream conditions tells you what will soon happen in your area.

Here’s a list of handy web sites that display river, bayou and stream levels around Lake Houston and the state. Explore them before an emergency.  Bookmark those that offer the best information for your area. 

Reference Guide
