BEAVER CREEK IMPOUNDMENT SURVEY 



While Montana is rich in aquatic resources, these water areas are 

 not evenh' distributed over the state. It is the Commisison's desire to 

 furnish fishing water in those areas where it is either not available or 

 where it is not available in sufficient quantity or in suitable quality. 

 In the course of a survey of the waters of Hill County, the District 

 Fisheries Biologist located a desirable dam site on Beaver Creek south 

 of Havre within the boundaries of the Beaver Creek Park. 



Since the Commission does not have on its staff men experienced 

 in dam construction and planning, they asked the State Water Conser- 

 vation Board to determine the feasibility of a project on Beaver Creek 

 and to plan the dam if it were found feasible. The State Water Con- 

 servation Board did this during 1954, and the Commission reimbursed 

 them for costs of the survey and planning. 



Plans have been developed for an earth and rock fill dam with 

 appurtenant concrete outlet and spillway structures. The dam would 

 be a compacted embankment 55 feet high and 20 feet wide on top. 

 The reservoir at normal water surface, eight feet below the top of the 

 dam, would average about 380 feet wide and 4,000 feet long, have a 

 surface area of 37 acres and a capacity of 540 acre feet. 



TONGUE RIVER REHABILITATION 



During the course of a routine fisheries survey it was noted that 

 the Tongue River below Tongue River Dam in Big Horn and Rosebud 

 Counties was heavily infested with rough and stunted pan fish. Plants 

 of brown trout had been made in the area, and while a few did 

 survive, nevertheless, no fishable population developed. In years past 

 this area of the river had provided desirable sauger fishing. 



Electrical shockers are a part of the fisheries biologists research tools. These 



are used to temporarily stun fish in study areas to allow brief but careful 



examination, ageing, and marking.
