Depends a lot on water temp. This has been a cold spring. Water temp in the Willie is only 48 or so right now. Some years it is in the low 50s by now. This coming week has a nice warming trend.
Small ponds of course heat up faster and fish well much earlier than bigger waters. I have not gone bass fishing yet this year (all my trips this winter have been chasing kokanee at Lake Merwin). I don't have any first hand experience yet this year but I will probably give the bass a try this coming weekend.
Good luck out there!
