Improving River Flows for Paddlefish and Beyond



This is Passport to Texas

The batteries in the radio transmitters used to track 47 paddlefish reintroduced to Caddo Lake more than a year ago are fading.

06—We’re still tracking some paddlefish, but we know this is about the time we’re not going to be able to track ‘em anymore.

Native to Caddo, paddlefish disappeared following construction of a dam upstream at Lake of the Pines in the late 1950s.

Tim Bister, with Inland Fisheries, says early data suggest changes Texas Parks and Wildlife and partners made to simulate natural river flows and spawning habitat, kept the rare fish in the Big Cyprus Bayou and Caddo Lake system.

21—Having the opportunity to restore a native fish into the system, is certainly a good idea. But, to tie it into more of these natural river flows, and the idea that not just paddlefish—but
many other species—need natural river flows and appropriate spawning habitat, it’s going to benefit those things for rivers in Texas.

Bister says while they’ll continue monitoring paddlefish, the ongoing work is more expansive.

12— We will always be trying to do something in the Big Cyprus Bayou / Caddo Lake system to maintain quality river flow and quality habitat, and to monitor the fish populations.

The Wildlife and Sportfish Restoration Program supports our series.
