There is a shallow spinnerbait bite at times,bu if you have need of other than the floating frog,horney toad fluke or senko and in 2 ft of water or less,.then its going to hunt for a bite with the other stuff.
While grass isnt prominent and could play a role,tradionally teh first four 95 percent of the time,would beat any deep cr ig ,jig bite going,that time of year.Agian grass is playing a role and mother nature may as well.
Id still bet you 100 bucks I could fish those and shallow at 179 and beat the stuffins out of your bag from deep water,I have been wrong occasionally will be again in another 20 years or so.
Best bet figgure out what patterns or how to catch those shallow fish in or around alternate veggies,they are there.
May be going down that way prior if so will relate what info i have at the time.Water is warmer than normal and needs to start that downslide in temp to trigger.
Most of the grass or alternate is past the rr bridge,in back pockets or bays.Bass bay being one of them.Some resemble cuts more than pockets and are small in size.Yet hold several keepers.
And if you have to resort to crigging toss a crigged dbbb.If you want one badly Steve has one hidden somewhere.
The only patterns up here i can think of without grass is those shallow points for schoolers and of course ledges. 3a,3b,4,7 ledges 9 thu 16 mouth of big sandy,inside main lake bouy line toss toward main lake,bunch just on other side of rr bridge main lake,which puts you next to bass bay,almost halfway to 179.
Ive put so much in will refrain in the future as time will tell.
