tidal bore growing closer to its pre-1968 levels: "We were actually anticipating a fairly modest increase in height. It seems to be already exceeding what we might have expected." He noted that an estimated 40,000 gaspereau had returned to the river, and called for more studies to determine the impact of the causeway's opening. Recreation Residents around the Petitcodiac have used the river for various recreational purposes. Trips were made annually via the river from Moncton to Beaumont for Feast of Saint-Anne celebrations with the locals. The Blakeson, a towboat owned by Blakeny and Sons, offered "moonlight cruises" in the early 1930s for 50 cents (approximately $6.50 in 2010 values). The service was popular until the towboat capsized in front of embarking passengers, causing them to lose interest. During their Environmental Impact Assessment in September 2005, AMEC cited recreational fishing and birdwatching as major pre-causeway activities. A fishery for Atlantic salmon existed downstream from the causeway for several years post-1968. The Moncton Naturalists' Club also publishes their Birding in the Moncton Area, a birdwatching guide covering sites from Sackville to Mary's Point. Other activities downstream from the causeway include boating, canoeing, kayaking, seal and harbour-porpoise viewing, and tour boating. On 24 July 2013, the North American record for surfing a single river wave was set by Wessels and Whitbread of California, who rode the Petitcodiac River's tidal bore . Before the opening of the causeway gates on 14 April 2010, the Petitcodiac River's headpond (west of the causeway), colloquially known as Lake Petitcodiac, was promoted by LAPPA as a recreational haven for residents in the area. According to the association, over 10,000 estimated hours of boating took place on the lake, in addition to canoeing, kayaking, motor boating, water skiing, jet skiing, sailing, and swimming. Fishing tournaments, dragon boat regattas, dog sledding, and snowmobiling were popular at the time as well. However, a study by the PWMG showed that fecal coliform levels in the headpond from June, July, and September 2009 exceeded 2,419 parts per 100 millilitres; more than 12 times the 200/100 ml recommended by the Canadian Water Quality Guidelines for recreational purposes. Bore Park, located in the area formerly known as La Chapelle, became a popular tourist location by 1907 for watching the Petitcodiac's tidal bore move up the river twice a day. The area features information about the wave, as well as a clock indicating the time
