Water releases have been cut back at one dam in Canada and could be curtailed soon from other dams in Canada and the US.
The changes come while hydrologists are predicting early season crests soon at several places along the Mouse River in North Dakota.
Three river gages along the Mouse are now registering levels in the 'moderate' flooding range, and a fourth is predicted to reach that stage in a couple of days.
Moderate flooding is reported west of Sherwood, before the river hits Lake Darling.
Downstream of Lake Darling, moderate flooding is reported east of Foxholm, and at Towner, and is predicted for Bantry by Saturday.
The river is projected to stay at or near the 'minor' flooding stage at Boy Scout Bridge, Logan, Sawyer, and Velva.
At all locations through Towner, the predictions see a rise of only another foot or so over the next several days.
Meanwhile, Canadian water managers cut releases in half at Alameda Dam - reducing the flow from that dam to about 350 cubic feet per second.
The total reported release rate from Alameda, Rafferty, and Boundary Dams is now a bit under two thousand CFS - lower than it's been in more than a week.
Water managers in the US and Canada will be meeting again Friday to decide on any further changes in releases.
The target level for Lake Darling is 15-93, and the lake is now at about 1593.3. That's several feet below its level of two years ago - although two years ago,
Lake Darling's level was rising quickly because releases had been shut off to allow for the runoff on the Des Lacs River to run through the system and reduce flooding in Burlington.
This year, there has been very little melting of the snow pack in either the Des Lacs or Mouse River watershed so the reservoirs are still low, to be ready to handle the runoff.
