Surf City Inland USA. Boise was and still is the gold standard for surf park wave performance. Two state-of-the-art WaveShapers create dozens of different wave combination at all river flows the only truly fully adjustable wave system ever done. The result - surfing 365 days a year and a flourishing surf community 500 miles from any ocean. A nice bonus, the project is a community park that turned a once deadly dam into a reliable irrigation diversion and arguably Boise's most iconic recreational venues.
