Any added cover like a brush pile or row of stumps is an added bonus. Under these circumstance first pitch the jig in the deeper water along the cover. If this does not create a bite try moving up into shallow water. Make sure you make repeated cast along all cover, for cold water bass can sometimes be non-aggressive. More than likely bass will be somewhere along the point, so be patient and work the jig slow.
Coves also offer a great location to intercept spring time bass.
If the bass are not on the points try moving back into the coves and pockets off the main river or lake. While in these places look to make a presentation to every piece of cover. If the bass are not in either portion of the lake there is one secret spot left for those of you who want to make a trip worth while. Bridge rip rap or any other rip rap banks can be dynamite for spring time bass on jigs. Rocks tend to warm faster than other places which in turn warms the water and activates the bait fish.
