Book excerpt: Excerpt from Federal-State Cooperative Snow Surveys and Water Supply Forecasts for Montana and Northern Wyoming (Upper Missouri and Upper Columbia River Basins) March first snow surveys over the Jefferson River Basin show an above average water content, except the extreme upper or southern portion of the Rock Creek area. This area is 12 per cent below average in the vicinity of Rock Creek Lakes, Lima Reservoir, and west of Dell. The Horse Prairie area west of Armstead and into the Big Hole and Wise River Basins, are above average by 30 to MO per cent. The Big Hole River should produce approximately acre feet between April first through September, or 3h per cent more than the average flow.
