Picha Creek Channel Restoration Services
Inter-Fluve was introduced to Picha Creek while walking 125 miles of the Sand Creek and Credit River in Minnesota during a watershed-level assessment. At that time, we identified more than 200 restoration projects by ranking them on a 1-11 scale. Picha Creek ranked at the top for restoration potential. Increased rainfall, tilling, and development pressures in the upper watershed were leading to channelization, resulting in river channel incisions up to 10 feet. Significant sediment loads were also being released into the system, with no sign of equilibrium.Most popular related searches

Inter-Fluve was later hired by Scott County to perform a channel restoration project on Picha and nearby Porter creeks. For Picha, we had two options: raising the channel bed or lowering the adjacent floodplain. Ultimately, we opted for a combination approach. To encourage infiltration and increase baseflow, we created a cobble-and-gravel riffle pool channel, and used adjacent sand and sandy loam soils as channel fill. In total, we helped to restore 3,000 feet of stream channel.
