Description: A cooperative research project by the Alaska Department Fish and Game, Yukon Flats National Wildlife Refuge (NWR), and Stevens Village Natural Resource Program was conducted at the mouth of the Dall River during 1995. An interview survey was used to estimate the level and type of visitor use of the Dall River between May 26 and September 5, 1995. The survey was also designed to provide a check on the Statewide Harvest Survey (SWHS) which estimates angler effort and northern pike Esox lucius harvest and catch. Total use by all visitors was estimated to be 613 (SE = 87) visitor days by 330 (SE = 33) visitors traveling in 107 (SE = 10) boats. Most use occurred in June and July (81%) and during weekends (83%). Most visits (90%) were by non-local people; Stevens Village residents composed 8% of the total during the survey period. Most of the visitors (265 of 282 interviewed) were sport fishing for northern pike. More than half (154 of 282) camped while in the survey area and 25 of 282 (9%) visitors were hunting. Most (82 %) visitor use occurred within the lower 10 mi of the river. Total fishing effort was estimated at 553 (SE = 79) angler days by 299 (SE = 29) anglers. Estimated total harvest of northern pike was 340 (SE = 43) fish. An additional estimated 985 (SE = 210) northern pike were caught and released. Total catch of northern pike in 1995 was estimated at 1,325 (SE = 243). These estimates are not significantly different from estimates provided by the SWHS for 1995 and are similar to the most recent five year averages from the SWHS (total effort - 619 angler days, total harvest - 320 northern pike, total catch - 1,757 northern pike).
