April 18, 2018 –  The snow and ice accumulation over the last several days raises the possibility of flooding in parts of the Rideau system as warmer conditions arrive on Friday. Rain and some melting has caused streamflows to increase throughout the watershed. Daytime temperatures above 10 degrees through the coming weekend and into next week can be expected to melt the remaining snow and ice. There is the potential for this meltwater to cause access issues in the low-lying communities on the Long Reach of the Rideau between Kars and Kemptville. Tributary streams such as Stevens and Cranberry Creeks…

April 11, 2018 – A weather system out of the mid-west U.S. has the potential to bring several forms of precipitation in significant amounts in to eastern Canada over the next week. Snow, rain and freezing rain may fall beginning tonight with showers or flurries. Tomorrow, rain is forecast to fall through the afternoon. Rain is expected to begin again late on Friday morning and continue into Saturday, changing to snow in the early morning finishing with as much as 20 centimetres. Rain is presently expected to resume on Sunday and continue into Monday. If the full amount of forecast…

Around the Rideau

The March/April 2018 Issue is now available. Find it in the Publications section of the website.
This spring RVCA’s Stewardship Program will be hand planting more than 10,000 trees and shrubs along our waterways with the goal of improving water quality, reducing erosion and enhancing wildlife habitat. What to Expect Join us for a day! A small team of planters will be travelling throughout the watershed to remote locations to plant bareroot seedling and potted plants. We work on all types of property and terrain including cottage shorelines, farm fields, valley lands, forest understory, tall grass and steep slopes. Remote locations mean there is very limited access to amenities (bathrooms, food etc.). A typical work day…
April 3, 2018 – Rain in the order of 20 millimetres is forecast for today and into the night that will cause water levels throughout the Rideau valley to increase beyond levels reached after rain on Saturday. How much levels increase will be limited by dropping temperatures and the changeover from rain to freezing rain or snow overnight and tomorrow. Peak flows from this weather are still expected to be less than average for the spring freshet. These may not be the actual freshet maximum flows. The Long Reach of the Rideau River, between Manotick and Kemptville, could have levels…

March 29, 2018 –  Barring a rain event not presently in weather forecasts, it is appearing that the spring freshet of 2018 in the Rideau valley may have already occurred on March 2 as a result of the above normal temperatures in the latter half of February that removed all of the snow. The snow that fell after the early March thaw, has gradually declined over the month with several sunny days and above freezing daily temperatures. With little snow and minor rainfall forecast, there is not expected to be enough runoff to cause significant increases in water levels in…

March 27, 2017, EASTERN ONTARIO — The Rideau Valley Conservation Authority (RVCA) Board of Directors celebrated World Water Day with release of their 2017 Annual Report. The report highlights the many achievements and on-the-ground projects that happened throughout the over 4,000 square kilometres of the Rideau watershed — activities that focus attention on the importance of water and supports World Water Day values. “RVCA is committed to supporting watershed health and the principles promoted through World Water Day,” said Sommer Casgrain-Robertson, RVCA General Manager. “It is fitting that we release our 2017 Annual Report on this special day and share…
EASTERN ONTARIO, March 12, 2018 — The Rideau Valley Conservation Authority (RVCA) has completed hazard mapping studies for Flowing Creek and Hobbs Drains — tributaries of the Jock River. Members of the public are invited to an upcoming open house to review regulations and hazard maps. These studies provide new mapping that show areas that are prone to natural hazards such as flooding and erosion and have natural environmental features such as wetlands. The mapping will be used by the City of Ottawa when updating their Official Plan and Zoning Schedules and in the review of development applications under the Planning…

Spring Outlook

March 9, 2018 –The winter of 2017-18 has been one of wide variations and periods of record cold. First snow on the ground to start this winter was relatively early at the beginning of November but little more fell until after December 28 followed by the onset of the record cold temperatures including -30 degrees on January 1. After ten days of frigid temperatures, a few days of warm temperatures reduced the snow cover significantly. That warm spell ended with a flash freeze. Precipitation in all its forms and widely varying temperatures continued through January into mid-February. Since February 19,…
