Rivers in the Wasteland received mostly positive reviews from music critics. Tony Cummings, founder of Cross Rhythms, rated the album a perfect ten squares, calling it a "delicious album" that "demonstrates once again that when you've got quality songwriting and a band on the top of their game, all resistance melts away."[10] At CCM Magazine, Matt Conner rated the album four stars out of five, calling the release a "spirited" affair on which has "Needtobreathe's signature Southern rock stomps circles 'round Bear Rinehart's distinct vocal for another 11-song feast that just might be their best yet."[7] At Milwaukee Journal Sentinel, Piet Levy gave the album a positive review, writing that "the inspiration can be found in the beauty of its lyrics", and that when the band gets around to praising the Lord that "the effect is more powerful than anything on the latest albums from Christian acts like Casting Crowns, MercyMe, Chris Tomlin or TobyMac."[17]
Timothy Monger of AllMusic rated the album three-and-a-half stars out of four, remarking that "If Needtobreathe's intention was to deliver a more down-to-earth and reflective record following The Reckoning's big-budget glitz, they've succeeded."[1] At New Release Tuesday, Kevin Davis rated the album a perfect five stars, writing that "Every song is absolutely amazing" because "[t]he very relatable and transparent words of these songs use poetic descriptions and biblical language throughout eleven stellar tracks".[15] Kate Padilla of The Spencer Daily Reporter liked Bear's vocal tone, claiming that singling out a few standout tracks would be a shear lesson in futility because "The entire thing is great, from beginning to end and back again."[18] At PopMatters, Jeff Koch rated the album five discs out of ten, cautioning how "these rivers run too shallow to irrigate this wasteland."[16]
