Great weather and stream conditions have arrived in time for the last weekend in April in southeastern Minnesota. Daytime air temperatures in the low 50’s and water temperatures from 47°-55°F in the Root River valley promise active trout and a crisp and sunny streamside experience through Sunday. Join us at the National Trout Center for the latest fishing updates, maps and a guide to the recently reconstructed 9-hole fishing course in Preston.
Hydrographic conditions are monitored in Minnesota through the DNR/MPCA Cooperative Stream Gaging program. Automated stream gauging stations throughout the state are available to the public at the DNR website: http://www.dnr.state.mn.us/waters/csg/index.html.
The current stream flow conditions presented here are based on the telemetry gauge at Carimona, MN, on the South Branch of the Root River 6 miles upstream of Preston, Minnesota. At this location, the gauge provides flow (discharge) data that result from recent precipitation, groundwater emergence, and surface runoff from the South Branch Root River watershed. Changes in Root River flows are often indicative of the flows in SE Minnesota streams and NE Iowa streams, and may also represent flows typical of the southern half of the midwest Driftless Area.
The graph below shows the past two weeks of water flows and stream temperatures this year (2018) in the South Branch Root River.
Stream flow rates (blue line in graph) of 150-200 cubic feet per second (CFS) are ideal for canoeing and kayaking between Forestville State Park and Lanesboro, while still offering safe streamside access for wading fishers. Stream temperatures (purple line) varying over a day-night range of 10°F ensure active feeding in daylight hours, and active insect hatching, particularly at dawn and dusk.
See our recent Trout Tyme blog article on stream flows and transparency for further information on judging water clarity. See also the MN DNR stream conditions report for this week at http://www.dnr.state.mn.us/areas/fisheries/lanesboro/stream_conditions.html.
