Each number along the river represents the flow rate at one of the hydromet guages.
500 cfs or below
500 – 1,000 cfs
1,000 – 2,000 cfs
2,000 – 5,000 cfs
5,000 + cfs
First and foremost, what are the recent trends on the river where you are going to be paddling? Is it going up, down, or staying pretty consistent. What’s going on up stream? Are the upstream gauges higher or lower than where you are going to be? How are they trending? What ever is happening up stream will eventually happen down stream.
Tip: Spikes in cfs at the Austin gauge (just below Longhorn Dam) usually take 12 to 24 hours to reach Bastrop. The distance between the two gauges is 62 miles.
Finally, what is going on with the weather? Compare radar patterns to a map of the Colorado River watershed. If its raining in the water shed, ALL of that water is trying to find its way into the river system.
