State Rids Rogers Lake Of Trash with Chemicals Thei Montana Fish and Game Department Department chemically treated 240-acre Rogers Lake Wednesday to eliminate thfe trash fish, Frank Stefanich, district fisheries supervisor supervisor for the department, announced announced today. Rogers Lake is located ·bout 19 miles west of Kalispell. , The fisheries official said the project marked the first time In Montana that a lake ^ias been rehabilitated to preserve the grayling, grayling, a rare game fish. Rogers Lake is the traditional home of the Montana grayling. In recent years, however, the lake has become ove.rrun with the red- sided shiner, to the detriment o£ grayling populations. This situation, situation, he said, has made rehabilitation rehabilitation of the lake necessary. Usually, a lake is rehabilitated to make better fishing, Stefanich explained, but Rogers Lake will be restored primarily to provide a source of grayling brood stock for planting In .other suitable Flathead Flathead Waters. : He said the adult grayling were removed from the lake in May, as they moved up a tributary stream to spawn. These fish are being held near Ashley Lake and will be returned'to Rogers ag; goon as the water becomes non-toxic. "Montana is the only state to have any-grayling left," the fisheries fisheries officials stated...... "Montana grayling are found In only two areas -- th.ei Red' Rock, Lakes area and .the v Flathead. Every effort is being «iade to pre' pre' vent this fine glme 'fish from ; becoming becoming extinct." ' i The fisheries supervisor also disclosed that 210-acre Dog Lake in Sanders County will be treated with fish toxicant Saturday to destroy destroy predominate trash fish populations, populations, to be followed next week by 180-acre Sophie Lake in Lincoln Lincoln County. Both lakes will probably be replanted in the spring with rainbow trout to provide improved fishing, he said. Fishery. biologists, game ward- efts, fish hatcherymen, and sportsmen sportsmen will assist with the trash eradicating projects. The public is invited to observe the operations. operations. Much preliminary work had to be done this summer to prepare the lakes for rehabilitation. rehabilitation. Stefanich and his assistants had to obtain the p^st history the lakes, complete gill net samplings, samplings, make aerial photograph!, take' depth soundings, and calculate calculate the volume of water' In each lake, so that proper amounts oi toxicant would be used. The toxicant to be used is Nox-Fish." Jt contains rotenone whjch kills fish by suffocation. toxicant, however, is harmless to man or livestock, and any./game fish which are killed by the cal in treating the lakes may safely eaten, it was pointed out. "Rehabilitation of fishing waters is in its Infancy in the Flathead area," Stefanich stated. "There are many more potentially fine trout waters in this part of tana, that, with the people's cooperation, Will be restored to good tr.out fishing In the?near.future." The fisheries official emphasized, emphasized, however, that before a can be restored by chemical treatment, public.access to:the waters must be N assured. · *
