FORT PECK GAME RANGE, FORT PECK, MONTANA. — May, June, July, August — I GENERAL A« Weather Conditionso Weather conditions through this report period were, on the average, cooler and wetter than normal. Attached to this report are the official weather reports as issued by the War Department for the past three months. Maximum temperature -- July 95,0° Mnimum temperature — May 33,0° B, Water Conditions. Fort Peck Lake continued to raise until July 23, when a continuous release of about 8,000 second feet was started. This caused the elevation of the lake to recede at about one-half inch per day and will continue until fall rains increase the flow of water to this rate in tributaries of the Missouri below Fort Peck Dam. On the upper part of the Missouri River the water was higher this spring than for the past twenty years, and, as a result, raised Fort Peck Lake much above the normal expectations. At its highest the lake was at an elevation of 2183.82 on July 23. The water in the lake was three- quarters of its depth of spill elevation (2240) and the lake was approxi mately one-third full. C. Fires. Through this period, one fire existed on the refuge in the town of Fort Peck, and was caused by sparks from the city dump. No tangible damage was done as the fire was on land that is in no way utilized. II WILDLIFE A, Migratory Birds, A trip of 129 miles up the Missouri River in late July provided an opportunity to make a census of waterfowl on Fort Peck Lake, Mallards were the only species observed, and 1500 of these were observed at the water1s edge on flooded farm land. The birds were in the flapper stage XikB lEPARTivIEKT U. S. Engineer Office Fort Peck, Montana Position of station - 48o00t25.53" N; MONTHLY METEOROLOGICAL BULLETIN Elevation 2280 ft.
