If you really, really have to fish the Jordan you might try on 5th west, a block south of 4800 south. And between 3900 So. and 4500 So. on 5th west...head west through the industrial area till you find the river. These are where the Cottonwoods enter the Jordan.
Other than that Plotty, you'll be within an hours drive of the famous Provo river, you can get in fairly easily about Deer Creek ( any baits are legal here ).
