. B. Hydrology - refer to maps on pages VI-? through VI-9. 1. Rice Creek - a maturing stream typified by a broad floodplain, meandering channel approximately 25-40 feet wide and 2 feet deep, stagnant oxbows and laterally eroding banks. Rice Creek is the principal stream in a 201 square mile watershed that originates at Clear Lake south of Forest Lake, and flows for a distance of 28 miles southwestward through an extensive chain of lakes in Anoka County passing across the northwestern corner of Ramsey County, reentering Anoka County and emptying into the Mississippi River at Fridley. Sections of the creek channel have been mechanically straightened in each of the segments. The creek has a fall of 1-foot per mile north of the Twin Cities Army Ammunition Plant (TCMP), and an average of 8 feet per mile southwestward of the TCMP. During seasons of high precipitation, the creek provides a suitable watercourse for canoeing. The Rice Creek Watershed District constructed a 5-acre desiiting basin and in-channel pond between Poppyseed Drive and the Minnesota Commercial Railway tracks at the south end of the trail corridor (New Brighton-Mounds View segment). The District removes and disposes of accumulated sediment . every 3-5 years. 2.
