Only trout fishing within reach will be at the Sipsey TAILWATER below the dam that impounds Smith Lake....that is probably about 45 minutes from Addison.
Info can be found:
To check water releases:
There is a Fly Shop on the Riverside that posts (Tenative) generation Schedules. Advise no wading during release.
By the way....they just stocked the Tailwater with 3k on 4/22
