The United States Geological Survey maintains the course of the river two levels. The first measuring point is located at Masardis ( ⊙ 46.5225-68.373055555556 ). The catchment area of the river at this point comprises 2309 km ². The highest recorded there runoff was 600 m³ / s, the lowest 1.1 m³ / s The second level measures data at Washburn ( ⊙ 46.776666666667-68.158055555556 ). The catchment area at this point covers 4282 km ². The highest recorded at Washburn river discharge is 1230 m³ / s, the lowest value is 2.1 m³ / s The maximum values occur during the spring thaw, the lowest water level is observed in the fall. The highest water levels caused at two measuring points by ice barriers caused floods. This happens quite often in this flow, such as in March and April 1999, in April and May 2003 and in April 2004.
