here are two places to check
www.wmi.org go to the fishing reports and asked the same question (s)
www.bassboatcentral.com
i know douglas is in that area, but the fishing there and on lenoir (about 1 hour SW) has always been tough for me....deeper and clearer water than i normally fish...there are some guys on both of those sites that can help you out...there is also trout fishing in and around pigeon forge..but i know absolutely nothing about trout fishing, and with you mentioning dale hollow i figured you'd be targeting bass...
don't dare miss the chance to go thru Cades cove,,,for the wildlife
